Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a user adjusts photographing parameter by sliding finger on screen, then the photographing parameter can be adjusted, but the operation efficiency is low and control is difficult due to requiring relatively fine finger action

Engineering Contradiction:

Improveease of adjusting photographing parameterVSAvoidoperation efficiency

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The patent introduces a foldable display as an intermediary mechanism between the user's physical action and the photographing parameter adjustment. The folding action of the display serves as a mediator that translates into parameter changes, eliminating the need for fine finger sliding on the screen. This intermediary mechanism significantly improves both ease of operation and operation efficiency.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the traditional mechanical finger-sliding interaction on the touchscreen with a mechanical folding action of the display itself. This substitution transforms the control mechanism from fine finger movements to broader folding motions, making the adjustment operation more efficient and easier to perform while maintaining precise control over photographing parameters.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Measurement precision

If a user performs fine finger action to adjust photographing parameter, then the parameter adjustment can be achieved, but the control becomes difficult and operation efficiency decreases

Engineering Contradiction:

Improveprecision of photographing parameter adjustmentVSAvoidease of controlling photographing parameter

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

The patent utilizes parameter changes in the folding angle of the display to control the photographing parameters. By mapping the folding angle (a physical parameter) to photographing parameters such as focal length, aperture, or exposure, the system achieves precise control without requiring fine finger actions. This parameter transformation maintains measurement precision while dramatically improving ease of operation.
