Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the smart key remote controller frequently communicates with the vehicle control system using multiple frequency modules, then the control functionality and responsiveness are improved, but the battery consumption increases significantly
Solution Approach 1:
The patent implements dynamic module activation where the second frequency signal module is activated or deactivated based on real-time detection of vibration values and signal strength. This dynamic adjustment allows the system to maintain control functionality when needed while minimizing energy consumption during normal operation, directly resolving the contradiction between productivity and energy usage.
Solution Approach 2:
The system changes operational parameters by monitoring vibration detection values and RSSI (Received Signal Strength Indicator) to determine when to activate the second frequency signal module. By changing the operational state based on detected parameters, the system optimizes the balance between maintaining control functionality and reducing battery consumption.
2Speed
If the second frequency signal module is activated continuously to ensure rapid response, then the responsiveness to user actions is improved, but the battery life is reduced
Solution Approach 1:
Instead of continuous activation, the system employs periodic monitoring of vibration detection values and signal strength, activating the second frequency signal module only when specific conditions are met. This periodic action maintains responsiveness when necessary while extending battery life by avoiding unnecessary continuous operation.
Solution Approach 2:
The system performs preliminary detection of vibration and signal strength conditions before activating the second frequency signal module. This preliminary action ensures that the module is activated only when actually needed, maintaining responsiveness while preventing premature battery depletion.
3Adaptability or versatility
If the system uses multiple frequency signal modules for comprehensive communication, then the adaptability to different communication scenarios is improved, but the device complexity increases
Solution Approach 1:
The patent implements a multi-functional communication system where a single smart key remote controller can operate with one or two frequency signal modules depending on conditions. The second frequency signal module serves multiple purposes: enhancing communication when signal strength is weak, enabling communication in challenging environments, and providing backup capability, thus achieving universality without permanent complexity.
Solution Approach 2:
The system dynamically adjusts its communication capability by activating the second frequency signal module only when needed based on vibration detection and signal strength measurements. This dynamic approach provides adaptability for different communication scenarios while avoiding the permanent complexity of having both modules continuously active.
