Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If remote control devices use storage batteries for power supply, then wireless control signal transmission is enabled, but the weight and size of the control device increase and periodic battery maintenance is required
Solution Approach 1:
The patent extracts the power supply function from the remote control device itself and relocates it to the vehicle's existing electrical system. The control device becomes purely a signal transmission unit, while power is supplied externally through the vehicle's wiring harness, eliminating the need for internal batteries and reducing device weight.
Solution Approach 2:
The patent leverages the vehicle's existing electrical system to power the control device, making the vehicle's power supply serve multiple functions: powering both the electronic device being controlled and the control device itself. This eliminates the need for dedicated power sources in the control device.
2Weight of moving object
If speech recognition systems are used for control, then battery-free operation is achieved, but recognition accuracy is insufficient and driver attention is compromised
Solution Approach 1:
The patent introduces a membrane switch as an intermediary input device that provides tactile feedback and precise control. This physical interface acts as a mediator between the driver's intent and the electronic device, ensuring accurate control signals without relying on speech recognition accuracy.
3Ease of operation
If speech recognition units are integrated into the electronic device, then wireless control is achieved, but manufacturing cost and design complexity increase significantly
Solution Approach 1:
The patent segments the control system into distinct functional components: the control device handles user input and signal transmission, while the vehicle's existing electrical system handles power supply. This modular approach simplifies design and manufacturing by allowing each component to be optimized independently.
4Ease of operation
If control devices are integrated into the steering wheel or dashboard, then driver accessibility is improved, but cable connections increase device complexity
Solution Approach 1:
The patent merges the power supply function with the control device by integrating it into the vehicle's existing electrical system through the wiring harness. This combination eliminates the need for separate cable connections between the control device and power source, reducing overall system complexity while maintaining accessibility.
