Design for manufacturability is the practice of designing a product to be easy to manufacture. It reduces cost and improves quality by simplifying the design. A65 Consulting helps medical device companies apply these principles to turn concepts into viable products.
1. Reduce Part Count
Combine components to lower assembly time and inventory costs. Fewer parts mean fewer fasteners, less assembly labor, and reduced inventory management. This approach simplifies the bill of materials and minimizes the risk of assembly errors. It also makes the device easier to service and repair in the field.
2. Standardize Components
Use off-the-shelf parts to avoid custom tooling and long lead times. Standard components are often cheaper and available from multiple suppliers. This reduces the need for custom molds or specialized manufacturing processes. It also simplifies supply chain management and reduces the risk of supply disruptions.
3. Optimize Tolerances
Apply GD&T to specify only the tolerances needed for function. Geometric Dimensioning and Tolerancing is a system for defining the allowable variation in a part. Over-tightening tolerances increases manufacturing cost without improving performance. A65 Consulting uses tolerance analysis to ensure parts fit and function correctly while keeping costs low.
4. Design for Assembly
Minimize the number of assembly steps and directions. Design for assembly is a method for reducing the complexity of putting a product together. It involves designing parts that can be assembled quickly and with minimal tools. This reduces labor costs and the chance of assembly errors.
5. Simplify Geometry
6. Choose Appropriate Materials
Select materials that are easy to process and cost-effective. Material selection impacts manufacturing cost, performance, and regulatory compliance. Choosing a material that is easy to process can reduce manufacturing time and cost. It also simplifies the supply chain and reduces the risk of material shortages.
7. Validate Early
Test prototypes to identify manufacturing issues before tooling. Early validation helps identify and resolve manufacturing issues before they become expensive problems. It ensures that the design is manufacturable and meets performance requirements. A65 Consulting builds and tests prototypes to validate the design and reduce risk.
Choosing the Right Approach
Start by reducing part count and standardizing components. Then optimize tolerances and simplify geometry. Finally, choose appropriate materials and validate early. This systematic approach ensures that your device is easy and cheap to manufacture.
