Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If extensive programming is used to achieve compatibility with different vehicle systems, then adaptability is improved, but energy consumption increases and setup time increases
Solution Approach 1:
The patent segments the memory into two distinct parts: additional memory for storing multiple vehicle manufacturer specifications and internal memory for storing the actively used configuration. This segmentation allows the sensor to load only the necessary configuration data into internal memory, minimizing energy consumption while maintaining adaptability across different vehicle systems.
Solution Approach 2:
The patent implements preliminary action by pre-storing multiple vehicle manufacturer specifications in the additional memory during manufacturing. During setup, the sensor pre-loads the specific configuration data needed for the target vehicle into internal memory, so that during normal operation, only the essential configuration needs to be maintained in power-consuming memory, thereby reducing ongoing energy consumption while preserving broad compatibility.
2Adaptability or versatility
If extensive programming is used to achieve compatibility with different vehicle systems, then adaptability is improved, but setup time increases
Solution Approach 1:
The patent extracts the bulk of configuration data storage from the main operational memory (internal memory) and places it in separate additional memory. During setup, only the specific configuration parameters needed for the target vehicle are extracted and loaded into internal memory from the additional memory, significantly reducing the time required for configuration while maintaining the ability to support multiple vehicle systems.
Solution Approach 2:
The patent performs preliminary action by pre-organizing multiple vehicle manufacturer specifications in the additional memory during manufacturing. This allows the setup process to quickly retrieve and load only the relevant configuration data into internal memory, rather than programming extensive configuration data during installation, thereby reducing setup time while preserving adaptability.
3Adaptability or versatility
If complete programming is transmitted wirelessly to achieve compatibility, then adaptability is improved, but transmission time increases and error susceptibility increases
Solution Approach 1:
The patent extracts and stores complete vehicle manufacturer specifications in additional memory during manufacturing. During wireless setup, only the specific configuration parameters needed for the target vehicle are transmitted and loaded into internal memory, rather than transmitting complete programming data, thereby reducing transmission time and minimizing error susceptibility while maintaining adaptability.
Solution Approach 2:
The patent performs preliminary action by pre-storing multiple complete vehicle manufacturer specifications in additional memory during manufacturing. This allows the wireless transmission during setup to only convey the specific configuration identifier or minimal parameters needed to activate the appropriate pre-stored configuration, dramatically reducing transmission time and error risk while preserving full adaptability to different vehicle systems.
