Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the secondary module has processor means for active identification and marriage processes, then the module marriage can be performed actively and reliably, but the device complexity and cost increase due to additional active components in the secondary module
Solution Approach 1:
The patent introduces a passive coding contact loop as an intermediary element between the primary module's detector and the secondary module. This passive loop carries identification information without requiring active components in the secondary module, thus maintaining reliability while reducing complexity. The coding contact loop acts as a mediator that enables communication and identification functionality without the need for processors or active electronics in the secondary module.
2Device complexity
If the secondary module lacks processor means, then the device complexity and cost are reduced, but the module marriage process becomes inefficient and cannot be performed actively
Solution Approach 1:
The patent implements a self-service mechanism where the passive coding contact loop automatically provides identification information when contacted by the primary module's detector. The secondary module does not need to actively participate in the identification process; instead, the electrical connection itself through the coding contacts automatically communicates the module type and configuration information to the primary module, enabling efficient marriage without processors.
3Device complexity
If a passive coding contact loop is used for secondary module identification, then the device complexity is reduced and secondary modules can operate without processor means, but the measurement precision and detection capability may be limited compared to active processor-based identification
Solution Approach 1:
The patent applies local quality by assigning specific coding patterns to different types of secondary modules through the arrangement and configuration of coding contacts. Each secondary module type has a unique local configuration of coding contacts that provides precise identification information. This allows the primary module's detector to accurately distinguish between different module types based on the specific local arrangement of contacts, achieving high identification precision without requiring active processors.
