Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If unique communication protocols are used for each automobile manufacturer, then the tire pressure monitoring device can operate with specific manufacturer systems, but the device complexity and variety of sensors required increases
Solution Approach 1:
The patent implements a universal tire pressure monitoring sensor that can operate with multiple different automobile manufacturer protocols. The sensor device is designed with the capability to support various communication protocols, eliminating the need for separate unique sensors for each manufacturer while maintaining full compatibility with their respective systems.
Solution Approach 2:
The patent employs dynamic protocol selection and switching mechanisms within the sensor. The sensor can adaptively change its communication protocol based on which automobile manufacturer system it is installed in, allowing a single static hardware device to dynamically adjust its behavior to match the required protocol.
2Reliability
If unique communication protocols are used for each automobile manufacturer, then the tire pressure monitoring device can communicate with specific vehicle systems, but the ease of maintenance and service operations deteriorates
Solution Approach 1:
By creating a universal sensor that works with multiple manufacturer protocols, the patent ensures reliable communication across different vehicle systems while simultaneously simplifying maintenance. Service technicians no longer need to diagnose and replace different sensor types based on manufacturer requirements; a single universal sensor type can be used for all manufacturers.
3Adaptability or versatility
If multiple communication protocols are stored in memory, then the device can operate with different manufacturers, but the manufacturing complexity and programming requirements increase
Solution Approach 1:
The patent implements a system where multiple communication protocols are pre-loaded into the sensor's memory during the manufacturing process. This preliminary action of pre-programming multiple protocols eliminates the need for complex field programming or configuration by service technicians, as the sensor is already prepared to operate with different manufacturer systems.
Solution Approach 2:
The sensor incorporates dynamic protocol selection capabilities that automatically or manually switch between pre-loaded protocols based on the installed vehicle manufacturer, simplifying the manufacturing process by using a single programmable platform rather than requiring separate programming for each sensor type.
