Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the circuit path design focuses only on probe structural configuration adjustments, then the design process is simple, but the circuit path efficiency is insufficient and component damage risk increases
Solution Approach 1:
The guide board is divided into multiple guide board modules, each with independent connection circuits. This segmentation allows each module to handle specific circuit paths independently, improving overall circuit efficiency while maintaining manageable design complexity through modular architecture
Solution Approach 2:
Guide board modules are introduced as intermediary components between probes and the DUT. These modules provide protective functions and optimize circuit paths, reducing direct stress on probes while improving signal transmission efficiency through dedicated connection circuits
2Reliability
If guide board modules are designed with parallel connection configuration, then circuit path efficiency improves, but device complexity increases
Solution Approach 1:
Multiple guide board modules use identical or substantially the same structural configurations and connection circuit patterns. This copying approach allows parallel connections to be implemented with standardized designs, improving circuit path efficiency while controlling complexity through reuse of proven module designs
Solution Approach 2:
Each guide board module is designed as a universal unit that can perform multiple functions: signal transmission, component protection, and mechanical guidance. The standardized multi-functional design allows parallel configuration without proportionally increasing overall system complexity
3Device complexity
If probes are directly connected to DUT without guide board modules, then device structure is simple, but component damage risk increases
Solution Approach 1:
Guide board modules serve as intermediary components positioned between the probes and the DUT. These modules absorb mechanical stress and electrical surges, protecting both the probes and DUT from damage while maintaining relatively simple overall device structure through modular addition rather than fundamental redesign

AI summary
A guide board mechanism includes two guide board modules spaced apart from each other. Each of the two guide board modules includes two guide boards, a spacing sheet sandwiched between the two guide boards, and at least two connection circuits that are formed on one of the two guide boards. In each of the two guide board modules, any one of the two guide boards has a plurality of thru-holes defined as at least two thru-hole groups, and the at least two connection circuits are arranged along the at least two thru-hole groups. Moreover, patterns of the at least two connection circuits in one of the two guide board modules are respectively identical to patterns of the at least two connection circuits in another one of the two guide board modules.
