- How Design for Manufacturing and Assembly (DFMA) affects the final product
Building a medical device carrying case requires coordinated expertise across engineering, materials science, and manufacturing. This article explains how each element is developed and why the decisions made at the design stage determine the quality of the final product.
Medical devices have become world-class, highly specialised equipment. Matching carrying solutions require an equally broad range of competencies, spanning mechanical and materials engineering, ergonomics, medical disciplines, manufacturing, economics, and marketing, to serve emergency medical professionals, hospital teams, clinical professionals, and patients effectively.
Balancing Design, Engineering, and Manufacturing
Effective medical case design means creating an integrated solution, not just a container, where usability, cleanability, and manufacturing feasibility are considered from the start.
In order to properly produce a custom-designed carrying case for a medical device, every aspect of its usage must be taken into account. Effective design, engineering, and manufacturing means creating an integrated value-added solution that is much more than a mere plastic storage or shipping box. Usability is a primary focus, and everything from ease of access and visibility of screens to the ability to clean and sterilize the case needs to be considered. And, with more medical products being developed that incorporate telecommunications and data transmission capabilities, case design elements that work with or even integrate chargers, docking stations, and stands are increasingly in demand.
Accessories that accompany main devices such as a user manuals, cables and connectors, battery packs, and disposables are also important to take into account when considering the development of a case or bag. When these components are worked into the overall design, the resulting carrying product, along with the accessories and the device, combine to become a cohesive, integrated system.
The main medical carrying solutions design, engineering and manufacturing considerations include:
Internal and External Organization of Carrying Cases:
Good internal organization means every component, device, cables, and accessory have a fixed, accessible position that speeds up setup and reduces errors.
Design must provide an organized arrangement of contained elements so that access, functionality and utility are optimal, beyond just being a simple holder.
Carrying Case Cleanability & Maintenance:
For medical applications, cleanability means surviving repeated disinfection with industrial-grade chemicals without seam degradation, material breakdown, or contamination risk.
Maintaining a clean and hygienic product and carrying product are especially paramount for medical applications, where disease and infection are risks, there’s also regulatory considerations and biocompatibility, increasing complexity of accomplishing this goal.
Carrying Case Durability and Protection:
Whether in a trauma bay or a routine clinic, medical equipment cases must absorb impact, resist moisture, and endure daily wear without compromising the device inside.
Regardless of usage environment, whether in the hectic pre-hospital rescue setting or calm, routine clinical environments, expensive and sensitive medical equipment needs protection. Good designs must offer impact resistance, guard against regular ongoing wear, and protect against potentially damaging elements such as rain or dust.
Carrying Solution Brand, Presentation & Appeal:
High-performance medical products deserve a case that matches. Branding, finish, and form factor all contribute to how a product is perceived by clinicians and patients alike.
Whether for professional or patient self-use, physical attractiveness and aesthetics are, more and more, taken into consideration for carrying products, as for the contained devices themselves. High-performance products need a look and feel to match. Working with an innovative custom case design company ensures you accomplish your functional and aesthetic goals.
Integration of Design & Development with Manufacturing:
Design for Manufacturing and Assembly (DFMA) ensures that a case which looks great on paper can actually be produced at scale, on time, and within cost.
When delivering a perfect carrying solution, great design is a must-have, but it is not enough. Often, if design for manufacturing and assembly (DFMA) is not taken into consideration in a project’s early stages, the result is a product that is either too difficult or too costly to practically manufacture. Considerations such as: Production line setup, mold making and tooling, automation vs. hand assembly, factory streamlining, scheduling, material availability and more must be taken into account- even at the design stages- in order to achieve the goal of a “perfect” carrying solution.
Focusing on Function: Case Manufacturing at its Core
Beyond dimensions and shape, a case must be built to survive the conditions its users actually work in, and that starts with understanding exactly how and where the device will be used.
Beyond a design that works with the specific product’s dimension, shape, weight, and accessories, it must also be constructed to meet the sometimes rigorous demands of its users. How and where a device will be used plays a big part in a case’s design geometrics and construction. For example, a portable heart defibrillator that is carried by an EMT will require a case that is durable, portable, and also provides high levels of impact protection because, in regular field usage, defibrillators tend to be roughed around or even accidentally dropped.
Openings, zippers, and handles require careful selection to ensure ergonomic ease of use. As well, seams and overlapping areas must be minimized where there might be a risk of contamination from bodily fluids or requirements include resistance to weather elements.
Of course, branding and presentation are other important elements. Cases typically need to be consistent in shape, look, and style with the product and other cases within a product line. And, if patients themselves will use the products, the design’s visual appeal may have an even more substantial importance.
Selecting Materials in Case Manufacturing
Material selection covers both external shell and internal padding, and the two must work together to deliver a solution that is functional, manufacturable, and compliant.
Both external and internal materials must work together to create a wide range of solutions that are functional, manufacturable, and marketable. Soft materials such as woven polyester, polyamide and neoprene are commonly used for custom soft sewn bags and pouches. (Read our Materials Guide below to learn more about the unique features of every type of material). Thermoformed EVA foam shells and reinforced fabrics are often preferred for semi-rigid cases. Some products such as ultrasound transducers require very durable materials such as polycarbonate or rigid polyamide to provide additional protection. There are also complex material solutions such as composites, laminates, and fabrics coated with robust and antibacterial TPU (thermoplastic polyurethane) that are the best options for certain applications, such as EMS products. Advanced manufacturing requires a high level knowledge of how to work with and blend all of these materials via technologies such as blow molding, injection molding and other advanced materials work.
Biocompatibility is paramount when determining the material selection of a medical carrying solution. Durability, weather resistance, impact protection, robustness, cleaning and maintenance, and IP Code ratings are some of the important selection variables that must be taken into consideration. There is a strong interrelation between specific designs and the materials that can be used for those designs. A deep understanding of both how the product will be manufactured and used is required.

Balancing Cost, Quality, and Regulatory Compliance
Using top-quality, compliant materials increases per-unit cost, but it protects market access, reduces liability, and directly contributes to the product’s long-term commercial success.
Medical equipment manufacturers are spending more than ever on the development, manufacturing, and marketing of their devices. Carrying solutions for these products are increasingly becoming a crucial component in the overall product offering. With the increasing complexities of medical products and of market demands, vendors realize that offering well-designed cases made from high quality materials can present a competitive edge. So, while it is true that using only top quality materials and high-quality manufacturing for the carrying solution may impact direct per-unit product costs, this quality control ultimately contributes to the overall market success of the product and the vendor’s profitability.
For example, a detail such as the location of a case zipper or the visibility of a screen through a transparent window in the carrying pouch can make the difference between a product that sells well and one that is rejected by consumers. To ensure that no detail is overlooked, a 360° approach to design, engineering and production is required.
The reality is that very few medical equipment manufacturers have the in-house capabilities necessary to deliver customized medical equipment carrying solutions that perfectly match their products’ needs. Just as the increased innovation of medical devices is increasingly becoming specialty specific and complex, so is the ability to design, develop and produce a perfectly matched carrying case for those products.
Providing a simple off-the-shelf storage case is no longer sufficient when it comes to medical devices. Adding value by including a product-specific carrying solution that becomes part of the product’s working system adds value and maximizes the product’s usability and market success.

Key Takeaways
- Medical carrying case design requires expertise across design, engineering, materials, and manufacturing, not just case-making
- Cleanability, biocompatibility, and regulatory compliance must be specified at the design stage, not retrofitted
- Material selection depends on use environment: EVA for semi-rigid cases, polycarbonate for high-impact, TPU laminates for EMS
- DFMA integration from day one prevents costly late-stage redesigns
- Off-the-shelf cases no longer meet the expectations of medical device buyers or their end users
Medical device manufacturers are investing more than ever in the devices themselves. The carrying solution should reflect that investment, not undermine it. A case that is designed, engineered, and manufactured with the same rigour as the device it protects becomes part of the product, not an accessory to it.

FAQs
What materials are used in custom medical device carrying cases?
Common materials include thermoformed EVA foam shells, woven polyester and neoprene for soft bags, polycarbonate for high-impact rigid cases, and TPU-coated fabrics for EMS applications. Material choice depends on the device’s weight, use environment, cleanability requirements, and applicable regulations.
What does biocompatibility mean for a medical carrying case?
Biocompatibility means the materials used in the case will not cause harm if they come into contact with patients or clinical staff. For medical cases, this influences foam selection, coatings, adhesives, and hardware — all of which must be tested and documented.
What is Design for Manufacturing and Assembly (DFMA) and why does it matter?
DFMA means engineering the case with production in mind from day one. Without it, a well-designed case may be too expensive or complex to manufacture at scale. Considering tooling, automation, and material availability early prevents costly redesigns later.
