Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If wireless programming method is used to configure TPMS, then programming speed is improved, but reliability deteriorates due to inability to immediately confirm configuration matching and risk of erroneous settings
Solution Approach 1:
The patent introduces a wired connection interface as an intermediary between the programming tool and TPMS sensor. This physical connection serves as a reliable communication channel that enables immediate confirmation of configuration matching through direct data exchange, eliminating the uncertainty inherent in wireless programming while maintaining programming efficiency.
Solution Approach 2:
The patent implements a feedback mechanism where the programming tool immediately receives and displays the ID code from the TPMS sensor after programming through the wired connection. This real-time feedback allows operators to confirm configuration matching and detect errors instantly, significantly improving reliability compared to wireless methods where confirmation is delayed or uncertain.
2Ease of operation
If wireless transmission is used for TPMS programming, then ease of operation is improved, but harmful factors increase due to unintended alteration of surrounding TPMS settings
Solution Approach 1:
The patent extracts the programming operation from the wireless environment and confines it to a wired connection between the programming tool and the target TPMS sensor. This physical connection establishes a dedicated communication path that is isolated from other TPMS sensors in the vicinity, ensuring that programming signals cannot be received by or affect surrounding systems.
Solution Approach 2:
The wired connection acts as an intermediary that physically isolates the programming operation from the wireless environment. This mechanical connection serves as a barrier that prevents programming signals from propagating to surrounding TPMS sensors, thereby eliminating the harmful effect of unintended alterations while maintaining ease of operation through straightforward plug-and-play connectivity.
3Adaptability or versatility
If memory space of TPMS is used to store communication protocols, then adaptability is improved, but device complexity increases due to limited storage capacity
Solution Approach 1:
The patent implements a copying mechanism where the programming tool stores multiple communication protocols in its own memory and selectively transmits the required protocol to the TPMS sensor through the wired connection. This approach transfers the storage burden from the TPMS sensor to the programming tool, which has greater memory capacity and can manage multiple protocols without increasing sensor complexity.
Solution Approach 2:
The patent shifts the protocol storage dimension from the TPMS sensor (limited memory) to the programming tool (unlimited memory). By moving the storage function to another device in the system, the patent enables unlimited protocol adaptability while keeping the sensor design simple and uncomplicated.
