Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a conventional portable light uses a fixed single illumination function design, then the device structure is simple, but the adaptability to different occasions and conditions is limited

Engineering Contradiction:
Improveadaptability to different occasionsVSAvoiddevice structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The light source body is separated from the main body through a connection member, allowing the light source body to be detached and replaced. This segmentation enables different light source bodies to be used for different occasions while keeping the main body structure simple and reusable.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The main body is designed with a universal connection member that can accommodate multiple types of light source bodies. This allows a single main body to serve multiple functions by simply changing the light source body, achieving adaptability without increasing overall device complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If the light source body is designed as a pre-mounted unit, then the device structure is simplified, but the flexibility to change light sources for various needs is reduced

Engineering Contradiction:
Improveflexibility to change light sourcesVSAvoidease of changing components
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The connection member is designed as a separable interface between the main body and light source body, enabling easy attachment and detachment. This segmentation provides both flexibility to change light sources and ease of operation through simple connection/disconnection actions.

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If multiple light source bodies are provided for different conditions, then the adaptability is improved, but the device complexity increases

Engineering Contradiction:
Improvediversity in applicationsVSAvoidnumber of components
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

By separating the light source body from the main body, the system allows multiple light source bodies to be used with a single main body. This segmentation reduces overall device complexity because the main body and its connection member need only be designed once, while multiple simple light source bodies can be added as needed.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The universal connection member design allows the same main body to work with multiple different light source bodies designed for various conditions. This universality achieves diversity in applications without proportionally increasing device complexity, as the main body structure remains constant.

Inventive Principle:
Principle #6Universality (Multi-functionality)
