Solution Overview

Problem

Conventional lighting fixtures have fixed light beams that cannot be adjusted without physically altering their height, and they are prone to moisture damage due to gaps between components, which can harm electrical components.

Innovation Solution

A lighting fixture with a moisture-resistant and adjustable illumination arrangement featuring a rotatably mounted lens assembly that allows adjusting the distance between illuminating elements and lenses to alter light beam angles and directions, while a sealing mechanism prevents moisture ingress.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the illuminating unit is mounted in a housing in an immovable manner, then the structure is simple and stable, but the light beams cannot be adjusted and the illumination arrangement lacks flexibility

Engineering Contradiction:

Improveadjustability of light beam directionVSAvoidcomplexity of mounting structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The lens assembly is mounted on a rotatable arm that can rotate relative to the housing, transforming the static mounting into a dynamic adjustable structure. This allows the light beam direction to be changed by rotating the lens assembly to different angles while maintaining a relatively simple overall structure.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The lighting fixture is divided into separate functional modules: the housing with illuminating unit, the rotatable arm, and the lens assembly. This segmentation allows each component to be optimized independently and facilitates the adjustable functionality without significantly increasing overall complexity.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If additional mounting fixtures or accessories are used to adjust the height of the lighting fixture, then the illumination requirements can be met, but the device complexity and cost increase

Engineering Contradiction:

Improveadjustability of illumination angleVSAvoidnumber of additional components

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The rotatable arm serves multiple functions: it supports the lens assembly, enables angular adjustment of the light beam, and maintains a compact structure. This multi-functionality eliminates the need for separate height adjustment fixtures or accessories, reducing overall device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Ease of operation

If cracks exist between the main housing and the lampshade or lens elements, then the structure allows for assembly and disassembly, but moisture can ingress and damage the electrical components

Engineering Contradiction:

Improveease of assembly and disassemblyVSAvoidprotection against moisture damage

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

A waterproof seal (flexible membrane) is introduced at the interface between the housing and the lens assembly. This seal prevents moisture ingress through cracks while allowing the structure to remain assembleable and disassemblable, maintaining both reliability and ease of operation.

Inventive Principle:

Principle #30Flexible shells and thin films

4Adaptability or versatility

If the distance between the illuminating elements and the optical lens is fixed, then the structure is simple and stable, but the illumination effects cannot be varied

Engineering Contradiction:

Improvevariability of illumination effectsVSAvoidcomplexity of adjustment mechanism

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The rotatable arm enables dynamic adjustment of the distance between the illuminating elements and the optical lens by rotating to different angles. This simple rotational movement provides variability in illumination effects without requiring complex adjustment mechanisms.

Inventive Principle:

Principle #15Dynamics
