Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional wire-based probe sets are used for large current transmission, then electrical measurement function is achieved, but abrasive wear and friction occur causing structural damage and reliability degradation
Solution Approach 1:
The patent extracts and removes the conventional wire-based transmission system from the measurement device. By eliminating the wires that cause friction and abrasive wear, the harmful factors are directly removed while the electrical connection function is maintained through the conductive cylinder and probe assembly structure.
Solution Approach 2:
The patent replaces the mechanical wire-based transmission system with a conductive cylinder and probe assembly structure. This substitution eliminates the friction and abrasive wear associated with wire movement while maintaining electrical connectivity through the conductive dome and needle cylinder mechanism.
2Reliability
If coarse wires are used inside the measurement device for large current transmission, then electrical connectivity is achieved, but heat accumulation occurs due to crowded wiring and poor heat dissipation
Solution Approach 1:
The patent extracts and removes the coarse wires from the measurement device interior. By eliminating these wires, the crowded wiring situation is resolved and heat generation from wire resistance is reduced, while the conductive cylinder and probe assembly provide alternative current transmission paths with better thermal management.
3Ease of operation
If probe sets with wires are fixed on the plate, then measurement function is achieved, but internal space is occupied by wires reducing heat dissipation capability
Solution Approach 1:
The patent extracts the wires from the measurement device interior, removing the space occupation caused by bundled wiring. The conductive cylinder and probe assembly structure occupies minimal space while maintaining electrical connectivity, thereby freeing up internal volume for improved heat dissipation.
4Ease of operation
If wires are shifted during probe contact and displacement, then measurement operation is enabled, but friction between wires occurs leading to structural damage and broken wires
Solution Approach 1:
The patent replaces the wire-based mechanical transmission system with a conductive cylinder and probe assembly structure. During probe contact and displacement, the new structure eliminates wire shifting and friction through its rigid conductive cylinder design, while the flexible needle cylinder accommodates movement without friction-induced damage.
