Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If illumination sources are added to improve low light image capturing, then image quality and brightness are improved, but device complexity increases

Engineering Contradiction:

Improveimage capturing illuminationVSAvoidillumination assembly structure

Core Design Contradiction:

Illumination intensityVSDevice complexity

Solution Approach 1:

The illumination assembly is divided into separate illumination sources (front side and rear side illumination sources) that can be independently controlled and positioned. Each illumination source is a distinct module that can be selectively activated based on capturing conditions, allowing the system to provide targeted illumination without requiring a fully integrated complex illumination system.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The illumination body is designed to be movable between different positions relative to the mobile device. The illumination securing assembly allows the illumination body to move between a first position (closer to the device) and a second position (farther from the device), enabling dynamic adjustment of illumination characteristics based on capturing requirements.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If multiple illumination sources are provided for front and rear capturing, then versatility in different capturing scenarios is improved, but device complexity increases

Engineering Contradiction:

Improveillumination for different capturing subsystemsVSAvoidillumination control system

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Different illumination sources are provided for different capturing scenarios: a front side illumination source for front camera capturing and a rear side illumination source for rear camera capturing. Each illumination source is optimized for its specific location and capturing direction, providing locally appropriate illumination without requiring a single complex universal illumination system.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The illumination assembly is designed to support multiple capturing subsystems (front and rear image capturing subsystems) using a single assembly structure. The same illumination securing assembly and movable illumination body can serve both front and rear illumination needs by positioning the appropriate illumination source, reducing the need for completely separate illumination systems.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Ease of operation

If the illumination body is made movable to adjust positioning, then illumination direction and coverage are improved, but device complexity increases

Engineering Contradiction:

Improveillumination positioningVSAvoidillumination securing assembly

Core Design Contradiction:

Ease of operationVSDevice complexity
