Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing calibration tools are used, then calibration can be performed, but the tools are specific to single types of vehicles and require repetitive calibration processes
Solution Approach 1:
The calibration device is designed with a universal base board and adjustable angle adjustment assemblies that can accommodate multiple types of vehicles. The device integrates both vertical plane calibration and radar wave reflection calibration functions into a single system, eliminating the need for different calibration tools for different vehicle types and reducing repetitive calibration operations.
Solution Approach 2:
The device employs adjustable angle adjustment assemblies with cam discs and cam spring plates that enable dynamic positioning of the base board at different angles. This dynamic adjustability allows the same device to adapt to various vehicle types and calibration requirements without requiring multiple fixed-purpose tools.
2Measurement precision
If software-dependent calibration methods are used, then angle calculations can be performed, but calibration needs to be repeated multiple times causing inconvenience
Solution Approach 1:
The device replaces software-dependent angle calculation methods with a mechanical angle adjustment system using cam discs and cam spring plates. The physical mechanical structure directly establishes precise angles through its geometry, eliminating the need for repeated software calculations and iterations, thereby reducing calibration time while maintaining precision.
Solution Approach 2:
The angle adjustment assemblies are pre-configured with cam grooves and positioning holes that define specific calibration angles in advance. This preliminary preparation of angular positions allows for direct and accurate positioning without requiring repeated measurements and calculations during the calibration process.
3Manufacturing precision
If multiple calibration tools are used for different vehicle types, then specific calibration requirements can be met, but device complexity and costs increase
Solution Approach 1:
The calibration device integrates multiple calibration functions (vertical plane calibration and radar wave reflection calibration) into a single universal system. The base board can be adjusted to different angles using the angle adjustment assemblies, allowing one device to replace multiple specialized calibration tools while maintaining manufacturing precision through its adjustable mechanical structure.
Solution Approach 2:
The device merges previously separate calibration functions into a single integrated system. The base board serves dual purposes: as a vertical plane calibration target and as a radar wave reflection surface. This consolidation reduces the number of separate tools needed while preserving calibration accuracy through the unified mechanical design.
