Solution Overview

Problem

Conventional LED mount bars are difficult to bend in the width direction, requiring multiple bars to be connected or specially fabricated to form desired shapes, which is time-consuming and costly.

Innovation Solution

A LED mount bar with staggered grooves on its side surfaces, allowing easy bending in the width direction, and featuring mounts and connection portions with zigzag forms for flexible curvature, enabling the arrangement of LEDs in various shapes without connecting multiple bars.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional LED mount bars are used, then the bar structure provides structural stability, but the bar cannot be easily bent in the width direction requiring multiple bars to be connected

Engineering Contradiction:

Improvebending capabilityVSAvoidnumber of bars to be connected

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The bar is divided into multiple segments along its length, with grooves formed at specific positions to create bendable sections. These grooves allow the bar to be segmented into rigid portions (for structural stability) and flexible portions (for bending), enabling the bar to conform to curved surfaces without requiring multiple separate bars to be connected.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The invention introduces grooves at specific positions and orientations on the bar surface, adding a new dimensional feature that enables bending in the width direction. These grooves create weak planes that allow controlled deformation along the groove lines, transforming the bar from a rigid one-dimensional structure to a flexible two-dimensional formable structure.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If conventional LED mount bars are used, then manufacturing is straightforward, but special fabrication is required to conform to required forms

Engineering Contradiction:

Improveform adaptabilityVSAvoidfabrication complexity

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The grooves are pre-formed on the bar during manufacturing, creating predetermined bend lines before the bar is installed. This preliminary action allows the bar to be easily bent into various forms during installation without requiring complex post-fabrication processes, thereby improving form adaptability while maintaining manufacturing simplicity.

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If multiple bars are connected to form desired shapes, then the required form can be achieved, but installation time and cost increase

Engineering Contradiction:

Improveshape flexibilityVSAvoidinstallation time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The invention merges multiple rigid bar segments into a single flexible bar structure by introducing grooves that enable bending. This combining approach allows one bar to replace multiple connected bars, eliminating the need for complex connections and significantly reducing installation time while maintaining the ability to form various shapes.

Inventive Principle:

Principle #5Merging (Combining)
