Innovation Solution

A light guiding key structure comprising a housing with a receiving cavity, a light emitting assembly, a switch assembly, a light shielding assembly, a light guiding member, a light transmitting member, and a light shielding film, which includes separate channels and components to isolate and direct light emissions from multiple light sources, allowing for simultaneous and regional display of different colors.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single key structure is used, then the device structure is simple, but it cannot simultaneously display multiple colors of light

Engineering Contradiction:

Improvelighting effectVSAvoidkey structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The key structure is divided into multiple independent light channels (first light channel and second light channel), each capable of transmitting different colored light. This segmentation allows the single key to display multiple colors simultaneously while maintaining a relatively simple overall structure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different regions of the key structure are assigned different light transmission properties. The first light channel transmits first colored light while the second light channel transmits second colored light, creating local quality differences that enable multi-color display without requiring complete structural redesign.

Inventive Principle:

Principle #3Local quality

2Adaptability or versatility

If multiple light sources are integrated in one key, then multiple colors can be displayed, but light emissions cannot be clearly separated

Engineering Contradiction:

Improvelighting effectVSAvoidlight separation

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The key structure incorporates separate light channels (first light channel and second light channel) that are spatially isolated from each other. This physical segmentation ensures that light from different sources remains clearly separated as it travels through distinct pathways to the display surface.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Light guiding members are introduced as intermediary components between the light sources and the display surface. These guiding members precisely direct and isolate light from different sources through separate channels, ensuring clear separation of light emissions while maintaining manufacturing feasibility.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Adaptability or versatility

If separate light channels are used for different colors, then regional display of multiple colors is achieved, but the structure becomes more complex

Engineering Contradiction:

Improvelighting effectVSAvoidkey structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Multiple light channels and light guiding members are merged into a single integrated key structure. The first light channel, second light channel, and their corresponding guiding members are combined within one key component, achieving multi-color regional display without creating separate independent structures for each color channel.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The key structure is designed as a multi-functional component that simultaneously performs multiple functions: it houses multiple light sources, provides separate light transmission channels for different colors, and displays multiple colors regionally all through a single integrated structure, thereby reducing overall device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)
