Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a real object distance d is used between the optical lens and the chart for testing, then the testing accuracy is maintained, but the testing space required becomes too large
Solution Approach 1:
An optical lens module is introduced as an intermediary component between the optical lens and the chart. This module simulates the optical path of a long object distance while physically occupying minimal space, thereby maintaining testing accuracy without requiring large testing space
Solution Approach 2:
The optical lens module creates an optical copy or simulation of the long object distance scenario. By using multiple lenses to replicate the optical characteristics of a distant object, the system achieves accurate testing results in a compact configuration
2Device complexity
If heat-generating elements are integrated with the optical lens module, then the device structure is simplified, but dust may enter the optical lens module through heat-dissipating holes to pollute the optical lenses
Solution Approach 1:
Heat-generating elements are extracted and separated from the optical lens module, placed in a dedicated control unit instead. This separation eliminates the risk of dust entering the optical system through heat-dissipating holes while maintaining manageable device complexity
Solution Approach 2:
The device is segmented into distinct functional units: the optical lens module for testing and the control unit for heat generation and control. This segmentation allows independent optimization of each unit, protecting the optical system from contamination while managing thermal requirements
3Adaptability or versatility
If multiple charts are used for different testing needs, then the testing versatility is improved, but the time required for changing charts and setup increases
Solution Approach 1:
The turret is designed to be rotatable, allowing dynamic selection of different charts during testing. This dynamic configuration enables quick switching between different testing scenarios without manual intervention, improving both versatility and efficiency
Solution Approach 2:
Multiple charts are pre-loaded onto the turret in advance. This preliminary preparation allows the system to switch between different testing configurations instantly by simply rotating the turret, eliminating setup time for each testing scenario

AI summary
An optical object distance simulation device is disclosed. The device has an optical lens module composed of a plurality of optical lens and the optical lens module is arranged between an optical lens and a chart for simulating the real object distance and reducing the space required for testing an optical lens. Moreover, the optical lens module is separated from a light-emitting element, a power supply or any heat-generating elements all separated from the optical lens module. Furthermore, the heat-dissipating elements are arranged near elements that generate substantial heat. Hence, not only does the present invention have a good heat-dissipating effect, but it also prevents external dust from polluting the optical lens module because of the positioning of the heat-dissipating element and the heat-dissipating hole.
