Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an arc-shaped lock with multi-angle adjustment is used, then adaptability is improved, but manufacturing precision deteriorates due to lack of angle limiting mechanism causing large angle clamping deviation
Solution Approach 1:
The patent replaces complex mechanical angle limiting mechanisms with a magnetic field-based positioning system. The magnetic positioning component generates magnetic field lines that interact with the magnetic sensor to automatically limit and precisely control the angle between display modules, eliminating the need for complex mechanical limiting structures while achieving both multi-angle adaptability and high precision.
Solution Approach 2:
The patent changes the physical state from mechanical contact-based angle limiting to magnetic field-based positioning. By utilizing magnetic field strength and direction as controllable parameters, the system achieves precise angle control without mechanical wear or complex limiting structures, resolving the contradiction between adaptability and precision.
2Adaptability or versatility
If an arc-shaped lock with arc-shaped guide groove structure is used, then angle adjustment capability is improved, but device complexity increases and volume enlarges
Solution Approach 1:
The patent eliminates the arc-shaped guide groove structure by replacing it with a magnetic field-based positioning system. The magnetic positioning component and sensor work together to provide angle adjustment capability without requiring complex mechanical guide grooves, significantly simplifying the overall structure while maintaining adaptability.
Solution Approach 2:
The patent extracts and removes the unnecessary arc-shaped guide groove structure from the system. By taking out this complex mechanical component and replacing it with a magnetic field-based solution, the device complexity and volume are reduced while preserving the essential angle adjustment capability.
3Ease of manufacture
If angle splicing is done by angle locking devices or arc-shaped locks with complex structures, then assembly is possible, but installation efficiency deteriorates due to difficult adjustment and assembly
Solution Approach 1:
The patent replaces complex mechanical angle locking devices with a magnetic field-based positioning and locking system. This substitution enables easier adjustment and assembly operations while maintaining secure locking, directly improving installation efficiency without sacrificing assembly feasibility.
Solution Approach 2:
The magnetic positioning component and sensor work together to automatically position and lock display modules at the correct angles without requiring complex manual adjustment procedures. This self-positioning capability significantly reduces installation time and improves efficiency while maintaining assembly feasibility.
