Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a complex adjustment structure with many parts is used to enable light exiting angle adjustment, then the light exiting angle can be adjusted, but the device complexity increases and costs increase

Engineering Contradiction:

Improvelight exiting angle adjustmentVSAvoidadjustment structure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines the light transmitting plate and rotating shaft into an integrated assembly where the light transmitting plate is directly mounted on the rotating shaft. This merging eliminates the need for separate adjustment mechanisms, reducing device complexity while maintaining light exiting angle adjustability through simple rotation of the combined structure.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The rotating shaft serves multiple functions: it supports the light transmitting plate, enables rotation for angle adjustment, and provides the rotational movement mechanism itself. This multi-functionality reduces the number of separate parts needed, thereby reducing device complexity while preserving the adjustment capability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If a complex adjustment structure with many parts is used to enable light exiting angle adjustment, then the light exiting angle can be adjusted, but the cost increases

Engineering Contradiction:

3Adaptability or versatility

If a complex adjustment structure with many parts is used to enable light exiting angle adjustment, then the light exiting angle can be adjusted, but the ease of operation decreases

Engineering Contradiction:

Improvelight exiting angle adjustmentVSAvoidoperation convenience

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The integrated design of the light transmitting plate mounted directly on the rotating shaft allows for straightforward rotation to adjust the light exiting angle. This merging eliminates complex control mechanisms, making the adjustment operation simple and intuitive for the user.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent employs a dynamic rotation mechanism where the light transmitting plate can be freely rotated around the rotating shaft to achieve different light exiting angles. This dynamic adjustment is simpler and more intuitive than static or multi-step adjustment mechanisms, improving ease of operation.

Function Achieved in This Case

The solution simplifies the structure, reduces costs, and facilitates user operation by allowing easy adjustment of light exiting angles.

Implementation Method 1

Light emitted from the light emitting plate comes out after passing through the light transmitting plate. When the light transmitting plate is driven to make a rotating movement around a center axis of the rotating shaft, a distance between the light transmitting plate and the light emitting plate changes, and a light exiting angle of the light which is emitted from the light emitting plate and then passes through the light transmitting plate coming out changes accordingly.
