Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sensor device is wired to the control device for signal transmission, then data transmission is reliable, but the wiring becomes complex and error-prone
Solution Approach 1:
The patent replaces the mechanical wiring system with a wireless communication system. The sensor device transmits operating parameters to the control device wirelessly, eliminating the need for physical connections. This substitution resolves the contradiction by removing the complex wiring while maintaining reliable data transmission through wireless protocols.
2Ease of operation
If batteries or accumulators are used to supply energy to the sensor device, then the device can operate autonomously, but regular recharging or replacement is required increasing maintenance effort
Solution Approach 1:
The patent implements self-service by having the sensor device generate its own operating energy from the vibrations it detects. The energy supply device converts the mechanical vibrations into electrical energy to power the sensor and communication components. This eliminates the need for external battery replacement or recharging, achieving autonomous operation without increased maintenance effort.
3Device complexity
If the sensor device is made completely wireless to reduce maintenance, then wiring complexity is eliminated, but energy supply becomes more challenging
Solution Approach 1:
The patent converts the harmful vibration (which can cause wear and instability) into a beneficial resource by using it to generate electrical energy through the energy supply device. The vibrations that were previously considered a source of mechanical stress are now harnessed to power the wireless sensor device, resolving the energy supply challenge while maintaining wireless operation.
