Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an external end-user unit with wireless communication is added for adjusting wiping area boundaries, then ease of operation and adaptability are improved, but device complexity increases
Solution Approach 1:
The system is divided into separate functional modules: the existing wiper device with control unit, and an external end-user unit with detection unit and camera. This segmentation allows the external unit to handle user interaction and detection tasks wirelessly, improving ease of operation while distributing complexity across independent components rather than consolidating everything in one device
Solution Approach 2:
A wireless communication interface acts as an intermediary between the external end-user unit and the control unit of the wiper device. This intermediary enables data exchange for setting and adjusting wiping area boundaries without physical connections, enhancing operational convenience while managing system complexity through standardized communication protocols
2Measurement precision
If a detection unit with camera is added for automatic detection of wiper arm position, then measurement precision and automation are improved, but device complexity and cost increase
Solution Approach 1:
The detection unit with camera enables the system to automatically detect and determine the position of the wiper arm and wiping area boundaries without manual intervention. The system serves itself by using the camera to capture images and the detection unit to process this visual data, automatically calculating positions and adjusting boundaries, thereby improving measurement precision and automation while keeping the added complexity manageable through self-contained functionality
Solution Approach 2:
The mechanical or manual methods for determining wiper arm position are replaced with an optical detection system using a camera and detection unit. This substitution enables non-contact, automated visual measurement of positions and boundaries, significantly improving measurement precision and enabling automatic adjustment without complex mechanical sensors or manual measurement devices
3Reliability
If the control unit sets wiping area boundaries exclusively within a fixed parameter range, then reliability is improved, but adaptability decreases
Solution Approach 1:
The system implements dynamic boundary adjustment within a fixed parameter range. The control unit is designed to accept and process adjustment requests from the external end-user unit, dynamically modifying the wiping area boundaries within pre-defined safety and operational limits. This dynamic capability within fixed constraints ensures reliability by preventing unsafe configurations while maintaining adaptability for user preferences and different environmental conditions
