Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If modules are connected to the main board without short detection, then device complexity is reduced, but reliability deteriorates due to unintended operable connections from misalignment
Solution Approach 1:
The short detector performs voltage application and comparison before the module is fully operational, identifying potential short circuits in advance. This preliminary detection prevents unintended operable connections from causing damage, thereby improving reliability without requiring complex real-time monitoring systems throughout operation.
Solution Approach 2:
The short detector acts as an intermediary component between the module and main board, mediating the connection by detecting voltage differences that indicate shorts. This intermediary device simplifies the overall system by providing a single point of detection rather than requiring complex interconnections with multiple safety mechanisms.
2Object-affected harmful factors
If short detection is implemented, then harmful factors are reduced, but device complexity increases due to additional detection components
Solution Approach 1:
The harmful factor of short circuit detection is extracted as a separate, dedicated function performed by the short detector. This isolation allows the detection mechanism to be simplified and focused on a single task, reducing the complexity that would arise from integrating multiple detection functions into a single complex system.
Solution Approach 2:
The short detector uses simple voltage application and comparison mechanisms that are inexpensive and straightforward to implement. Rather than employing complex, expensive monitoring systems, the invention uses basic electrical measurement principles that are cost-effective and minimize added complexity.
3Measurement precision
If voltage comparison is performed continuously, then measurement precision is improved, but use of energy increases
Solution Approach 1:
The short detector performs voltage comparison at specific intervals or at key moments during module operation, rather than continuously monitoring. This periodic measurement approach maintains adequate detection precision for identifying shorts while significantly reducing energy consumption compared to continuous monitoring schemes.

AI summary
A computing device includes a module that connects to a main board and a short detector. The short detector applies a voltage to a first electrical contact of the module; while the voltage is applied: makes a comparison of a second voltage on a second electrical contact of the module to the voltage; makes a determination, based on the comparison, that the first electrical contact is connected to the second electrical contact via a short circuit; and in response to the determination, initiates remediation of the short circuit.
