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 repeated calibration operations
Solution Approach 1:
The patent applies universality by designing a calibration tool that can be used across multiple vehicle types. The base board with rotating shaft and positioning holes allows the same tool to accommodate different radar mounting positions and angles for various vehicle models, eliminating the need for separate calibration tools for each vehicle type.
Solution Approach 2:
The patent implements preliminary action through pre-established geometric relationships in the base board design. The fixed rotating shaft, positioning holes, and angle markings are pre-configured to provide direct visual alignment references, allowing calibration to be performed in a single operation without repeated software calculations or iterative adjustments.
2Measurement precision
If software-dependent calibration methods are used, then deviation angles can be calculated, but the process requires repeated calibration operations
Solution Approach 1:
The patent replaces software-based calculation systems with a mechanical alignment system. The base board provides physical reference lines, angle markings, and positioning features that enable direct visual measurement and alignment, substituting computational methods with tangible mechanical guides for determining deviation angles.
Solution Approach 2:
The calibration tool is designed to be self-sufficient with built-in reference markings and geometric features that provide automatic alignment guidance. The tool itself contains all necessary reference information (angle markings, positioning holes, reference lines) to perform calibration without external software assistance, making the process self-contained and operationally simple.
3Reliability
If existing calibration methods are used, then radar calibration can be performed, but the process is complex and inconvenient
Solution Approach 1:
The calibration device is segmented into distinct functional components: a base board with positioning holes, a fixed rotating shaft, mounting brackets, and angle adjustment assemblies. Each component has a specific function, and their modular structure simplifies both the device design and the calibration process, making it easier to understand and operate while maintaining reliability.
