Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed light trail generation parameter is used in light stream shutter mode, then the shooting process is simple and stable, but the shooting form becomes single and cannot meet diverse user requirements

Engineering Contradiction:
Improveshooting form diversityVSAvoidparameter control complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies dynamics by transforming the fixed light trail generation parameter into a dynamically adjustable one. The system provides real-time controls that allow users to modify light trail parameters during the shooting process, enabling the shooting form to adapt and change based on user needs while maintaining operational simplicity through an intuitive interface.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements parameter changes by allowing users to adjust light trail generation parameters such as quantity, length, and distribution during shooting. This enables diverse shooting forms including star trails, light painting, and other creative effects by changing the parameters of light trail generation without requiring complex device modifications.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If multiple light trail parameters are adjustable in real-time, then shooting form diversity is enhanced, but the control interface and system complexity increase

Engineering Contradiction:
Improveshooting form diversityVSAvoidparameter adjustment ease
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent applies segmentation by dividing the light trail generation parameters into distinct, independently controllable aspects such as light trail quantity, length, and distribution. Each parameter can be adjusted separately through dedicated controls, making the complex parameter adjustment process more manageable and easier to operate while maintaining shooting form diversity.

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If light trail generation parameters are fixed, then the shooting process is stable and easy to operate, but user requirements cannot be met and shooting forms remain single

Engineering Contradiction:
Improveshooting operation simplicityVSAvoidshooting form diversity
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent implements self-service by providing users with direct control over light trail generation parameters. Users can independently adjust parameters according to their own creative requirements without needing complex professional settings or assistance, maintaining ease of operation while enabling diverse shooting forms through user-driven parameter customization.

Inventive Principle:
Principle #25Self-service
