Engineering Contradictions & Design Principles

VSEngineering 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

Engineering Contradiction:
Improvecalibration accuracyVSAvoidcalibration box structure
Core Design Contradiction:
Measurement precisionVSDevice complexity

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.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

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.

Inventive Principle:
Principle #24Intermediary (Mediator)

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

Engineering Contradiction:
Improveambient light interferenceVSAvoidcalibration box assembly
Core Design Contradiction:
Object-affected harmful factorsVSEase of manufacture

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.

Inventive Principle:
Principle #1Segmentation

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

Engineering Contradiction:
Improveimage clarityVSAvoidambient light exposure
Core Design Contradiction:
Measurement precisionVSObject-affected harmful factors

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.

Inventive Principle:
Principle #3Local quality
