Solution Overview

Problem

Conventional LED lighting fixtures are compact, making it challenging to incorporate an adjustment mechanism that allows the lighting body to rotate or swing relative to the shade, limiting their adaptability to various environmental needs.

Innovation Solution

The LED lighting fixture features a shade with an annular groove and a connecting ring that enables the illumination main body to rotate or swing, utilizing a spring ring for engagement with the groove and sleeves for increased friction, allowing for adjustable illumination direction without complex mechanisms.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If conventional LED lighting fixtures are made compact, then space is saved and structure is simplified, but the ability to incorporate adjustment mechanisms is limited

Engineering Contradiction:

Improvefixture sizeVSAvoidlighting direction adjustment

Core Design Contradiction:

Volume of moving objectVSAdaptability or versatility

Solution Approach 1:

The connecting ring is disposed within the annular groove of the shade, nesting the adjustment mechanism inside the fixture structure. This allows the illumination main body to rotate or swing relative to the shade without increasing the overall fixture volume, while still providing lighting direction adjustment capability

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The illumination main body is designed to be dynamically adjustable relative to the shade through the connecting ring mechanism. The illumination main body can rotate or swing to change lighting direction, transforming a static compact fixture into a dynamically adaptable lighting system

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If an adjustment mechanism is added to allow lighting body rotation, then lighting direction adaptability is improved, but device complexity increases

Engineering Contradiction:

Improvelighting direction adjustmentVSAvoidmechanism complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The adjustment mechanism is segmented into distinct functional components: the annular groove in the shade, the connecting ring with first and second ends, and the illumination main body. This segmentation allows each component to perform its specific function (constraining, connecting, and rotating/swinging) independently, simplifying the overall mechanism while maintaining adjustability

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The connecting ring acts as an intermediary element between the shade and the illumination main body. It provides the rotational and swinging motion capability while being constrained by the annular groove, serving as a simple mediator that enables adjustment without requiring complex mechanical linkages

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

An LED light fixture (1) has a shade (10), an illumination main body (40) and a connecting ring (30). The shade (10) has an annular groove (11) and the connecting ring (30) is disposed therein. The connecting ring (30) has a first end (31) and a second end (32), wherein the first end (31) and the second end (32) are connected to the illumination main body (40). Thus, the illumination main body (40) is able to rotate or to swing relative to the shade (10).
