Light Fixture With Integrated Handle At Center Of Gravity

Solution Overview

Problem

Conventional light fixtures are difficult to carry, especially when installed at elevated locations, due to uneven weight distribution and the need for additional parts that increase weight and cost, leading to stress on the installer's hand during transport.

Innovation Solution

A light fixture with an integrated handle positioned at its center of gravity, eliminating the need for additional parts and ensuring balanced carrying without tilting or rocking.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a conventional light fixture is carried with both hands, then the user can transport it, but it causes stress on the installer's hand and is difficult when installation location is elevated

Engineering Contradiction:

Improveease of carryingVSAvoidstress on hand

Core Design Contradiction:

Ease of operationVSStress or pressure

Solution Approach 1:

The handle is merged with the light fixture housing as a single integrated component. The handle is formed by molding the housing material itself, eliminating the need for separate handle parts and their attachment hardware. This integration reduces the overall number of components and simplifies the structure while providing a dedicated carrying interface that distributes weight ergonomically.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The handle is pre-positioned at the center of gravity location during the housing molding process. This preliminary positioning ensures that the handle is optimally located for balanced carrying before the light fixture is ever handled by the installer. The center of gravity positioning is built into the design from the outset, preventing tilting and rocking during transport.

Inventive Principle:

Principle #10Preliminary action

2Ease of operation

If a carrying handle is retrofitted onto the light fixture, then carrying is possible, but additional parts increase the overall weight and cost

Engineering Contradiction:

Improvecarrying capabilityVSAvoidoverall weight

Core Design Contradiction:

Ease of operationVSWeight of moving object

Solution Approach 1:

The handle is merged with the light fixture housing as a single integrated component. The handle is formed by molding the housing material itself, eliminating the need for separate handle parts and their attachment hardware. This integration reduces the overall number of components and simplifies the structure while providing a dedicated carrying interface that distributes weight ergonomically.

Inventive Principle:

Principle #5Merging (Combining)

3Ease of manufacture

If the handle is positioned on the top or bottom end of the light fixture, then it can be attached, but the light fixture tilts or rocks during transport due to uneven weight distribution

Engineering Contradiction:

Improvehandle attachmentVSAvoidstability during transport

Core Design Contradiction:

Ease of manufactureVSStability of the object's composition

Solution Approach 1:

The handle is pre-positioned at the center of gravity location during the housing molding process. This preliminary positioning ensures that the handle is optimally located for balanced carrying before the light fixture is ever handled by the installer. The center of gravity positioning is built into the design from the outset, preventing tilting and rocking during transport.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The handle position is asymmetrically placed according to the specific center of gravity location of the light fixture rather than being symmetrically positioned at the geometric center or endpoints. This asymmetric positioning optimizes the weight distribution and balance point for carrying, ensuring stability during transport.

Inventive Principle:

Principle #4Asymmetry
