Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple sensors (camera, LIDAR, radar) are used to detect objects in the environment, then the detection capability is improved, but the device complexity increases
Solution Approach 1:
The patent combines multiple sensor types (temperature sensor, pressure sensor, shear force sensor, proximity sensor, accelerometer sensor) into a single multi-modal tactile sensor assembly integrated into the vehicle exterior. This merging approach maintains comprehensive detection capability while reducing overall system complexity compared to using separate sensors distributed throughout the vehicle.
Solution Approach 2:
The multi-modal tactile sensor serves multiple functions simultaneously: it detects temperature, pressure, shear force, proximity, and acceleration. This universal sensor design replaces what would traditionally require multiple separate sensors, thereby improving detection capability across multiple physical quantities while reducing device complexity.
2Ease of operation
If a touch sensor or proximity sensor is used in the exterior of the vehicle for door unlocking, then the ease of operation is improved, but the functionality is limited
Solution Approach 1:
The multi-modal tactile sensor extends the functionality of exterior touch sensors beyond simple door unlocking to include vehicle movement control. By integrating multiple sensor modalities (temperature, pressure, shear force, proximity, accelerometer), the system can detect various types of tactile interactions and translate them into different control commands, thereby improving both ease of operation and adaptability.
Solution Approach 2:
The system dynamically adapts its functionality based on the type of tactile interaction detected. Different combinations of sensor signals trigger different vehicle responses, allowing the same physical interface to serve multiple purposes depending on the user's intent, thus enhancing versatility while maintaining ease of operation.
3Adaptability or versatility
If the vehicle exterior comprises an array of multi-modal tactile sensors, then the adaptability is improved, but the manufacturing complexity increases
Solution Approach 1:
The tactile sensor system is divided into discrete multi-modal sensor units that can be individually manufactured and then assembled into arrays on the vehicle exterior. Each sensor unit contains all necessary sensor types (temperature, pressure, shear force, proximity, accelerometer), allowing for modular manufacturing that reduces overall complexity while enabling flexible deployment across different vehicle surfaces.
4Ease of operation
If multi-modal tactile sensors are used to detect tactile interactions for vehicle movement control, then the ease of operation is improved, but the measurement precision requirements increase
Solution Approach 1:
The system merges signals from multiple sensor modalities (temperature, pressure, shear force, proximity, accelerometer) to detect and interpret tactile interactions. By combining these different measurement types, the system achieves robust detection capability that compensates for the precision requirements of individual sensors, enabling accurate vehicle movement control through simple exterior touches.
