Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a diagnostic learning process is added to the production line to distinguish installation positions of mixed slave modules, then positioning accuracy is improved, but production complexity increases and production pace is impacted
Solution Approach 1:
The patent applies preliminary action by pre-configuring position detection pins and level signal pins during the manufacturing process. The position detection pins are physically connected to different level signal pins (high level or low level) based on the predetermined installation positions, so that when the Bluetooth slave module is installed, it automatically reads the corresponding position information without requiring any additional diagnostic learning process on the production line.
Solution Approach 2:
The patent extracts the position identification function from the complex diagnostic learning process and implements it through simple electrical connections. The position information is encoded in the level conditions of the level signal pins, and the Bluetooth slave module directly reads this information through the position detection pin, eliminating the need for complex diagnostic software processes.

3Measurement precision
If position detection pins are connected to different level signal pins for each installation position, then position identification accuracy is improved, but device complexity increases
Solution Approach 1:
The patent applies local quality by assigning different level conditions (high level or low level) to level signal pins based on the specific installation positions. Each Bluetooth slave module at a particular position has its position detection pin connected to a level signal pin with a specific level condition, creating a unique local configuration that enables accurate position identification without requiring complex processing.
Solution Approach 2:
The patent uses parameter changes by encoding position information through the level conditions (high or low) of the level signal pins. The Bluetooth slave module reads the level condition of the position detection pin and uses this parameter (high/low level) to identify its installation position, transforming the physical position into an electrical parameter that can be easily processed.
