Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the conventional TPMS sensor position setting method is used, then the ID and position of each TPMS sensor can be set, but the operation procedure is complicated and time-consuming due to sequential deflation and inflation of tires
Solution Approach 1:
The patent extracts and removes the unnecessary deflation and inflation steps from the sensor position setting process. By using a setting tool to directly input location codes into TPMS sensors, the method eliminates the harmful intermediate steps of tire pressure manipulation while achieving the same learning objective.
Solution Approach 2:
The patent performs preliminary action by pre-programming location codes into the setting tool before the sensor position setting process. This allows the system to directly transmit position information to sensors without requiring physical tire pressure changes, thereby saving time and simplifying the operation.
2Adaptability or versatility
If the conventional TPMS sensor position setting method is used, then the ID of each TPMS sensor can be memorized, but it cannot set warning threshold temperature value, warning threshold pressure value or other warning detection factors
Solution Approach 1:
The patent makes the setting tool universal by enabling it to perform multiple functions: inputting location codes, transmitting position information, and configuring warning threshold parameters (temperature and pressure values) for TPMS sensors. This multi-functional approach eliminates the need for separate configuration processes.
Solution Approach 2:
The setting tool acts as an intermediary device that bridges the gap between the user and the TPMS sensor system. It provides a unified interface for configuring both position information and warning threshold parameters, thereby preventing loss of configuration information and enabling comprehensive sensor setup.
3Productivity
If the conventional TPMS sensor position setting method is used, then the learning of sensor positions can be completed, but the user needs to deflate and inflate tires one after another sequentially
Solution Approach 1:
The patent replaces the mechanical system of tire deflation and inflation with an electronic/information-based system. By using a setting tool to wirelessly transmit location codes to TPMS sensors, the method substitutes physical tire pressure manipulation with digital information transmission, thereby improving productivity and reducing procedural complexity.
Solution Approach 2:
The patent uses copying by transmitting location code information from the setting tool to the TPMS sensors wirelessly. This information copying approach replaces the need for physical tire pressure changes, enabling rapid sensor position learning without complex mechanical operations.
