Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple components are connected to a housing using conventional connection structures (screws, snap-fit fasteners), then the device can be assembled with multiple functional components, but the connection structures are easily damaged by force during replacement and maintenance, causing failure
Solution Approach 1:
The housing is divided into a first housing component and a second housing component that can be separated, allowing the combined modular structure to be inserted or removed as a complete unit. This segmentation enables component replacement while protecting internal connection structures from direct external force
Solution Approach 2:
Multiple components (board card, interface panel, functional modules) are combined into a single integrated combined modular structure that is inserted into the housing as one unit. This merging reduces the number of separate connection points and protects internal connections from damage during maintenance
2Ease of manufacture
If a split-type plastic housing is used to connect multiple components, then the housing can be assembled from multiple parts, but the housing appears unaesthetic with visible mating lines and requires beautifying lines to improve appearance
Solution Approach 1:
The housing is segmented into first and second housing components with a specific mating structure that allows assembly while minimizing visible seams. The segmentation enables manufacturing flexibility while the precise mating design reduces aesthetic impact
Solution Approach 2:
The mating surface between housing components is designed with specific local geometric features that create a flush, aesthetically pleasing joint. The local quality of the mating surface is optimized to minimize visible lines while maintaining ease of assembly
3Object-affected harmful factors
If plastic materials with better chemical resistance are used to prevent cracking from cleaning agents, then the housing resistance to cleaning agents is improved, but the production cost increases
Solution Approach 1:
The patent uses conventional plastic materials that are cost-effective and can be easily manufactured, accepting that the housing may require replacement after exposure to harsh cleaning agents rather than using expensive chemically-resistant materials. This approach reduces production costs while maintaining functionality during the device's primary service life
4Adaptability or versatility
If the medical device is structurally designed with maximized configuration to include all functional modules, then the device can perform all medical functions, but the device volume becomes relatively large, making it inconvenient to transfer in hospital or on battlefield
Solution Approach 1:
The device is segmented into a permanent housing structure and removable combined modular structures containing functional modules. This allows the device to be configured with only the necessary modules for each specific medical scenario, reducing volume when full functionality is not required
Solution Approach 2:
The device configuration is made dynamic through the ability to easily add or remove combined modular structures based on the specific medical task. The device can be compact for transport and then expanded by inserting required functional modules at the point of use
