Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If traditional optical module designs are used, then optical functionality is achieved, but the module occupies large volume in at least two dimensions
Solution Approach 1:
The optical module is divided into immovable and movable parts, with the optical assembly mounted on a movable part that can be driven to move or tilt relative to the immovable part. This segmentation allows the optical functionality to be maintained while reducing the overall volume occupied by the module in at least two dimensions.
Solution Approach 2:
The connecting unit employs a multi-dimensional arrangement where connecting assemblies are positioned at different heights along the main axis direction. This vertical stacking approach reduces the horizontal footprint of the optical module while maintaining structural stability and optical performance.
2Volume of moving object
If the movable part is made smaller to reduce module size, then volume is reduced, but movement control precision may be affected
Solution Approach 1:
The patent replaces traditional mechanical connection structures with a magnetic connection system. Magnetic coils and magnetic elements are used to achieve precise control of the movable part's movement and tilting without direct mechanical contact, thereby maintaining high precision while reducing the size of the movable part.
Solution Approach 2:
The patent employs magnetic fields and electromagnetic forces to control the position and orientation of the movable part. By adjusting electrical parameters (current, voltage, frequency) to the magnetic coils, precise control over the movement and tilting angles is achieved, maintaining measurement precision despite reduced physical dimensions.
3Area of stationary object
If connecting assemblies are arranged along the main axis to reduce footprint, then area is reduced, but structural complexity increases
Solution Approach 1:
The connecting unit is designed as an integrated structure that simultaneously performs multiple functions: mechanical support, magnetic field generation, and positional control. By combining these functions into a single multi-functional component, the overall structural complexity is managed while achieving compact arrangement along the main axis.
Solution Approach 2:
The patent merges the connecting assemblies and magnetic components into an integrated unit that operates along the main axis. This consolidation reduces the horizontal footprint area while the modular design of the integrated unit keeps the structural complexity manageable through standardized interfaces and configurations.
