Solution Overview

Problem

Traditional lighting systems lack adaptability, leading to uneven illumination and difficulty in changing ambiance or lighting needs as spaces evolve, with fixed direction and intensity that cannot be easily adjusted.

Innovation Solution

A lighting unit with a hollow hemispherical body and a rotatable sphere containing a light source and translucent/opaque portions, allowing for adjustable light direction and intensity through rotational manipulation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional stationary lighting fixtures are used, then the lighting system is simple and easy to install, but the lighting direction and intensity cannot be adjusted, leading to uneven illumination and inability to adapt to changing space needs

Engineering Contradiction:
Improveadjustability of lighting direction and intensityVSAvoidcomplexity of lighting system structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies the dynamics principle by making the sphere containing the light source rotatable within the hemispherical body. The sphere can rotate to different positions, allowing the lighting direction to be dynamically adjusted from downward to sideways illumination. This dynamic element resolves the contradiction by providing adaptability without requiring multiple separate fixtures or complex adjustment mechanisms.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The lighting device is segmented into distinct functional components: a fixed hemispherical body and a rotatable sphere containing the light source. This segmentation allows independent movement of the lighting element while maintaining a simple overall structure, enabling adjustability without increasing system complexity.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If traditional fixed lighting fixtures are used, then the installation is straightforward, but the ambiance and lighting needs cannot be modified as space usage changes

Engineering Contradiction:
Improveflexibility to change lighting ambianceVSAvoidease of adjusting lighting
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The rotatable sphere design enables self-service operation where the user can manually adjust the lighting direction by simply rotating the sphere to the desired position. The intuitive rotational movement requires no complex controls, switches, or additional mechanisms, making the adjustment process as easy as the original fixed fixture while providing full adaptability.

Inventive Principle:
Principle #25Self-service

3Illumination intensity

If traditional lighting systems are used, then the structure is simple, but areas of uneven illumination occur with over-lit and shadowed areas

Engineering Contradiction:
Improveuniformity of light distributionVSAvoidcomplexity of lighting mechanism
Core Design Contradiction:
Illumination intensityVSDevice complexity

Solution Approach 1:

The dynamic rotatable sphere allows the light source to be positioned at different angles and orientations, enabling the user to direct light to specific areas that need illumination and avoid shining light into areas that should remain in shadow. This dynamic positioning capability achieves uniform illumination control without requiring multiple light sources or complex multi-directional fixtures.

Inventive Principle:
Principle #15Dynamics
