Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional protective case uses a fixed wiring structure for electrical connection, then the structure is simple and easy to manufacture, but the electrical contact becomes unreliable due to wire movement and poor positioning
Solution Approach 1:
The patent applies the dynamics principle by making the support plate movable instead of fixed. The support plate can slide along the guide slot in the sidewall, allowing the electrical connector to dynamically adjust its position. This dynamic structure eliminates wire movement issues while maintaining reliable electrical contact, resolving the contradiction between reliability and complexity.
Solution Approach 2:
The patent introduces a guide slot as an intermediary element between the fixed case structure and the movable support plate. The guide slot constrains the movement of the support plate to a specific path, ensuring reliable electrical contact while allowing necessary adjustment. This intermediary structure resolves the contradiction by providing controlled mobility without excessive complexity.
2Adaptability or versatility
If a protective case is designed for a predetermined device size, then the manufacturing precision is high for that specific size, but the adaptability to different device sizes is poor
Solution Approach 1:
The support plate's ability to move along the guide slot provides dynamic adaptability to different device sizes. When a device of varying size is inserted, the support plate automatically adjusts its position along the guide slot to maintain proper electrical contact alignment. This dynamic adjustment preserves manufacturing precision across different device sizes while enhancing adaptability.
Solution Approach 2:
The guide slot structure serves multiple functions: it guides the support plate movement, constrains lateral displacement, and accommodates different connector positions. This universal structure allows the same protective case design to work with multiple device sizes without sacrificing positioning precision, resolving the contradiction between adaptability and precision.
3Reliability
If wires are used for electrical connection in the protective case, then the ease of manufacture is high, but the stability of electrical contact deteriorates due to wire movement
Solution Approach 1:
The patent extracts the wires from the electrical connection system and replaces them with a rigid connector mounted on the movable support plate. This extraction eliminates wire movement issues that cause unstable electrical contact. The connector is directly attached to the support plate, which moves as a unified structure, ensuring stable electrical contact while maintaining ease of manufacture through standardized connector assembly.
