Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the light emitting units are fixed with respect to the light source, then the device structure is simplified, but the installation position cannot be arbitrarily selected

Engineering Contradiction:
Improveinstallation position flexibilityVSAvoiddevice structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The device is divided into separate components: a light source unit and multiple light emitting units that can be independently positioned. The optical fiber transmits light from the fixed light source to the movable light emitting units, allowing segmentation of the fixed and movable functions.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The light emitting units are made dynamically positionable along the guide part while the light source remains fixed. This dynamic positioning capability allows arbitrary installation positions to be selected based on different use environments without changing the overall device structure.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If multiple light emitting units are used with fixed positions, then the illumination coverage is improved, but the adaptability to different environments is reduced

Engineering Contradiction:
Improveenvironmental adaptabilityVSAvoidinstallation flexibility
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The light emitting units can be dynamically positioned at different locations along the guide part according to the specific illumination requirements of different environments. This dynamic positioning maintains ease of operation while improving environmental adaptability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The device is designed with universal applicability through the guide part structure that accommodates light emitting units at various positions. The same device can be adapted to different environments by simply repositioning the light emitting units, providing multi-functionality without requiring multiple specialized devices.

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