Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If high machining precision is used for mechanical components, then manufacturing precision and optical axis orthogonality are improved, but manufacturing cost increases exponentially
Solution Approach 1:
The patent divides the mechanical platform into multiple modular components (base, bearing support, adjustment mechanism) that can be manufactured separately with standard precision and then assembled. This segmentation allows each component to be produced using conventional machining methods rather than requiring the entire assembly to be machined to high precision, thereby reducing manufacturing cost while maintaining overall precision through the adjustment mechanism.
Solution Approach 2:
The patent incorporates an adjustment mechanism that allows for preliminary positioning and orthogonality calibration of the optical axis before final assembly and operation. This preliminary action enables compensation for accumulated machining tolerances from individual components, achieving the required optical axis orthogonality without requiring each component to be manufactured at high precision, thus reducing overall manufacturing cost.
2Manufacturing precision
If high machining precision is used for mechanical components, then optical axis orthogonality is improved, but machining cost increases
Solution Approach 1:
The patent employs an adjustable and movable bearing support structure that can dynamically adjust the position and orientation of the imaging module. This dynamic capability allows the system to compensate for machining tolerances and achieve optimal optical axis orthogonality through adjustment rather than relying solely on high-precision machining, thereby reducing machining costs while maintaining precision.
Solution Approach 2:
The patent utilizes an adjustment mechanism that changes the positional parameters of the imaging module relative to the base. By allowing variation in position and orientation parameters, the system can achieve the required optical axis orthogonality through adjustment rather than requiring fixed high-precision machining, thus reducing machining costs.
3Ease of manufacture
If standard precision mechanical components are used, then manufacturing cost is reduced, but optical axis orthogonality and image clarity deteriorate
Solution Approach 1:
The patent introduces an adjustment mechanism as an intermediary element between the base and the imaging module. This intermediary component enables fine-tuning of the optical axis orthogonality after assembly, compensating for the lower precision of standard machining components. The adjustment mechanism acts as a mediator that transforms standard precision components into a system that achieves high optical precision.
Solution Approach 2:
The patent replaces reliance on purely mechanical high-precision machining with a combination of standard machining plus mechanical adjustment. The adjustment mechanism provides a secondary degree of freedom that compensates for machining tolerances, substituting the need for expensive high-precision machining with a more cost-effective adjustment-based solution.
4Ease of manufacture
If machining tolerances exist in high-precision components, then manufacturing becomes easier, but optical axis orthogonality and image quality are compromised
Solution Approach 1:
The patent incorporates an adjustment mechanism that enables preliminary calibration of the optical axis orthogonality before final operation. This preliminary action allows the system to compensate for machining tolerances in high-precision components, ensuring that even if individual components have tolerances, the final assembled system achieves the required optical precision and image quality.
Solution Approach 2:
The patent implies a calibration or adjustment process that provides feedback on the optical axis alignment. Through this feedback mechanism, the system can detect deviations from optimal orthogonality caused by machining tolerances and make corresponding adjustments to restore image quality, thereby compensating for the presence of machining tolerances in components.
