Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the calibration opening is oriented horizontally or upward, then the calibration component is easily exposed to ambient light, but this makes the calibration process simpler; however, ambient light interference causes unclear images and reduces calibration accuracy
Solution Approach 1:
The calibration opening is oriented obliquely downward at a specific angle rather than horizontally or upward, changing the spatial dimension of light exposure. This angular orientation blocks ambient light from directly entering the calibration space while still allowing the measuring device to capture images of the calibration component through the opening.
Solution Approach 2:
A light-transmitting cover is introduced as an intermediary element between the ambient light environment and the calibration component. This cover selectively transmits light, allowing the measuring device to obtain clear images of the calibration component while blocking harmful ambient light interference.
2Object-affected harmful factors
If the calibration box is designed with simple structure, then the device is easier to manufacture, but it cannot effectively block ambient light; however, adding complex structures like oblique opening and light-transmitting cover improves light interference blocking
Solution Approach 1:
The calibration box is divided into multiple functional components: the calibration component, the obliquely oriented calibration opening, the light-transmitting cover, and the fixing member. Each segment performs a specific function, with the oblique opening and light-transmitting cover working together to block ambient light while maintaining manufacturability through modular assembly.
3Measurement precision
If the calibration opening is made larger to improve image capture, then more light can enter for better imaging, but more ambient light interference occurs; however, reducing the opening size blocks ambient light but reduces image quality
Solution Approach 1:
The light-transmitting cover is applied locally to the calibration opening, providing selective light transmission properties at the critical interface. This allows the opening to maintain sufficient size for image capture while the cover's special light-transmitting quality blocks harmful ambient light wavelengths or directions.
