Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional holding devices (screws, adhesives, clip connections) are used, then the light source can be held securely, but the device becomes inflexible and difficult to manufacture

Engineering Contradiction:

Improvesecure holding of light sourceVSAvoiddifficulty of manufacture

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The holding device is divided into separate modular components: a first holding element with a holder for the first end of the light source, and a second holding element with a holder for the second end. This segmentation allows each component to be manufactured independently and assembled together, simplifying the manufacturing process while maintaining secure holding capability through the distributed holder structure.

Inventive Principle:

Principle #1Segmentation

2Reliability

If traditional holding devices are used, then the light source can be held, but installation and replacement become cumbersome and time-consuming

Engineering Contradiction:

Improveholding capabilityVSAvoidinstallation and replacement time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The holding device incorporates movable components in both the first and second holding elements that can dynamically adjust their position. The holders can move along guiding structures to accommodate different light source positions, enabling quick insertion and removal of light sources without requiring complex alignment procedures, thus reducing installation and replacement time while maintaining reliable holding.

Inventive Principle:

Principle #15Dynamics

3Ease of manufacture

If fixed holding structures are used, then manufacturing is simplified, but the device becomes inflexible and prone to handling errors

Engineering Contradiction:

Improvesimplicity of manufactureVSAvoidflexibility in handling

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The holding elements incorporate movable holders that can dynamically adjust their position within the holding structure. These movable components are guided by guiding structures that allow controlled movement in specific directions, providing flexibility to accommodate different light source positions and orientations while maintaining manufacturing simplicity through the use of standard mechanical components.

Inventive Principle:

Principle #15Dynamics

4Ease of manufacture

If simple holding elements are used, then the device is easier to manufacture, but positioning precision and stability against vibrations are reduced

Engineering Contradiction:

Improveease of manufactureVSAvoidpositioning precision

Core Design Contradiction:

Ease of manufactureVSManufacturing precision

Solution Approach 1:

The holding device segments the positioning function into multiple holders distributed at different locations along the light source. Each holder is a separate component that can be precisely positioned relative to the light source ends, enabling high positioning precision through the cumulative effect of multiple precise positioning points while maintaining ease of manufacture through modular construction.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The holding device replaces traditional mechanical fastening mechanisms (screws, adhesives) with a system of movable holders guided by guiding structures. This substitution allows for precise positioning through geometric constraints and guided movement rather than complex fastening operations, achieving high positioning precision while maintaining manufacturing simplicity.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
