Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If complex sensor units and evaluation electronics are integrated into the vehicle actuation system, then the functionality and user convenience are improved, but the device complexity and cost increase
Solution Approach 1:
The sensor unit and evaluation electronics are extracted from the vehicle actuation system and relocated to the user's mobile device. The mobile device detects movement sequences using its own sensors (accelerometer, gyroscope) and communicates the evaluated movement data to the vehicle-side receiving unit, thereby simplifying the vehicle system while maintaining advanced functionality.
Solution Approach 2:
The mobile device acts as an intermediary between the user and the vehicle actuation system. It performs the complex sensing and evaluation functions, then transmits the processed movement sequence data to the vehicle, mediating the interaction and reducing the complexity burden on the vehicle system.
2Adaptability or versatility
If sophisticated sensor units and evaluation electronics are integrated into the vehicle actuation system, then the functionality is improved, but the manufacturing cost increases
Solution Approach 1:
The expensive sensor unit and evaluation electronics are extracted from the vehicle production line and relocated to the user's mobile device, which already possesses these capabilities. This extraction significantly reduces the bill of materials and manufacturing cost for the vehicle while preserving the sophisticated functionality through the mobile device's contribution.
Solution Approach 2:
The mobile device serves multiple functions: it acts as the sensor unit, the evaluation electronics, and the communication interface. By leveraging the universal capabilities of modern smartphones and tablets, the system avoids duplicating these expensive components in every vehicle, thereby reducing manufacturing costs while maintaining versatility.
3Ease of operation
If vehicle-side sensor units and evaluation electronics are used, then the actuation system can detect movement sequences, but the device complexity and cost increase for vehicle models without such equipment
Solution Approach 1:
Instead of equipping the vehicle with sophisticated sensors to detect user movements, the system inverts the approach by using the user's mobile device as the sensor. The mobile device detects the user's movement sequences and communicates this information to the vehicle, which only needs a simple receiving unit, thereby enabling contactless operation without complex vehicle electronics.
