Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the memory module is configured with small parts to connect to the driving mechanism, then the memory module can be integrated with the actuator, but the manufacturing complexity increases and the manufacturing efficiency decreases
Solution Approach 1:
The patent combines multiple separate components (memory gear, contact member, circuit board, support member, sealing element, and washer) into a single integrated memory module assembly. This merging approach allows the module to connect to the driving mechanism as one unit, reducing assembly steps and improving manufacturing efficiency while maintaining the necessary integration capability with the actuator.
Solution Approach 2:
The memory module is designed as a multi-functional component that simultaneously provides memory storage, mechanical engagement (through the memory gear with the auxiliary gear), electrical contact (through the contact member and circuit board), structural support (through the support member), and sealing (through the sealing element). This universal design enables a single module to perform multiple functions, reducing the need for separate components and simplifying the overall system.
2Adaptability or versatility
If the memory module is configured with small parts to connect to the driving mechanism, then the memory module can be integrated with the actuator, but the manufacturing time increases
Solution Approach 1:
The memory module components are pre-assembled into a complete functional unit before integration with the actuator. The memory gear, contact member, circuit board, support member, sealing element, and washer are all prepared and configured in advance as a unified assembly, which then connects to the driving mechanism in a single step. This preliminary preparation eliminates the need for on-site assembly of multiple small parts, significantly reducing manufacturing time and improving productivity.
3Volume of moving object
If the memory module size is reduced, then the miniaturization goal is achieved, but the manufacturing complexity increases
Solution Approach 1:
The patent employs a nested arrangement where smaller components are housed within or around larger ones to achieve miniaturization. The contact member is positioned within the receiving region of the memory gear, the circuit board is mounted on the support member, and the sealing element encloses these components. This nesting strategy reduces the overall volume of the memory module while maintaining all necessary functional elements, and the modular nested structure actually simplifies manufacturing compared to distributed small parts.
