Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If a light strip is used to emit light in the data cable, then the data cable can provide visual indication, but heat generation increases

Engineering Contradiction:
Improvelight emissionVSAvoidheat generation
Core Design Contradiction:
Illumination intensityVSTemperature

Solution Approach 1:

The patent replaces the light strip (electrical/thermal system) with a plastic optical fiber system that transmits light from the joint rather than generating it along the cable. This substitution eliminates the heat generation issue while maintaining visual indication capability, as the optical fiber merely transmits light without significant heat production.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Illumination intensity

If an optical fiber is used to emit light, then light emission is achieved, but the light is too dazzling

Engineering Contradiction:
Improvelight emissionVSAvoidglare
Core Design Contradiction:
Illumination intensityVSObject-affected harmful factors

Solution Approach 1:

The patent applies a frosted layer specifically at the outer surface of the optical fiber where light exits. This local modification diffuses the light only at the emission point, reducing glare in that specific area while maintaining the optical fiber's light transmission properties in its core structure.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The frosted layer modifies the optical properties of the fiber surface by scattering light, effectively changing how the light appears from intense and direct to diffuse and softened. This optical transformation reduces the dazzling effect while preserving the visual indication function.

Inventive Principle:
Principle #32Color changes

3Ease of operation

If the data cable is made flexible for easy handling, then ease of operation improves, but the cable becomes vulnerable to bending damage that is hard to detect

Engineering Contradiction:
ImproveflexibilityVSAvoiddamage detection
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent incorporates a light sensor in the joint that continuously monitors the light transmission through the optical fiber. When the fiber is damaged due to bending or impact, the light transmission changes, and the sensor detects this change, providing immediate feedback through a different colored light indication. This allows real-time detection of damage while maintaining cable flexibility.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The optical fiber serves multiple functions: it provides visual indication of cable status (normal operation), and simultaneously acts as a sensor for detecting bending or impact damage. This multi-functionality enables the same component to address both the flexibility requirement and the damage detection requirement.

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

4Object-affected harmful factors

If the frosted layer is made thick to reduce glare, then glare reduction improves, but the structural integrity and responsiveness to impact decreases

Engineering Contradiction:
Improveglare reductionVSAvoidimpact detection sensitivity
Core Design Contradiction:
Object-affected harmful factorsVSStrength

Solution Approach 1:

The patent optimizes the thickness of the frosted layer to a specific range that balances light diffusion and structural responsiveness. The layer is thick enough to effectively scatter light and reduce glare, but thin enough to maintain structural integrity and allow the layer to break or change properties when subjected to significant impact, enabling damage detection.

Inventive Principle:
Principle #35Parameter changes
