Solution Overview

Problem

Existing power supply methods for LED lamps on shelves are inconvenient, messy, and difficult to maintain due to the need for perforations or wire management, and current fixing methods for power-taking heads are unreliable and prone to damage.

Innovation Solution

An electricity taking head with an integrally molded rail connector and mounting base, featuring swing arms and a press part that allows easy connection and disconnection to a power supply rail using elastic materials, simplifying installation and removal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If magnetic fixing, buckle fixing, or tight-fitting fixing is used to position the power-taking head, then the power supply rail can provide power at different positions, but the structure becomes more complex and the reliability is reduced due to additional components that are prone to damage or wear

Engineering Contradiction:
Improvepower supply at different positionsVSAvoidfixing structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent extracts the positioning function from the fixing structure. The power supply rail body itself provides positioning through its geometric shape and engagement features, while the fixing function is achieved through the elastic contact connector that naturally maintains contact through elastic deformation, eliminating the need for separate magnetic, buckle, or tight-fitting fixing mechanisms

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent merges the positioning and fixing functions into a unified structure. The elastic contact connector simultaneously achieves both positioning (through its engagement with the rail body) and fixing (through elastic retention), consolidating multiple functions into a single integrated component rather than separate fixing mechanisms

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If magnetic fixing, buckle fixing, or tight-fitting fixing is used to position the power-taking head, then the power supply rail can provide power at different positions, but the reliability is reduced due to components that are easy to damage or wear

Engineering Contradiction:
Improvepower supply at different positionsVSAvoidfixing structure
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The elastic contact connector performs self-service by using its own elastic properties to maintain continuous contact with the conductive strip. The elastic deformation automatically compensates for positional variations and wear, eliminating the need for external fixing components that require maintenance or are prone to failure

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The elastic material provides beforehand cushioning by absorbing shocks and deformations before they can cause damage. The elastic contact connector's flexibility allows it to withstand repeated insertion and removal without damage, preventing wear and failure before they occur

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

3Ease of manufacture

If perforations are set on the shelf or wires are wound from the back to the front, then power can be supplied to LED lamps, but the installation becomes inconvenient and maintenance becomes difficult

Engineering Contradiction:
Improvepower supply setupVSAvoidinstallation and maintenance
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

The patent segments the power supply system into a modular power supply rail that can be independently installed and configured. The rail body with integrated conductive strips and contact connectors can be assembled separately and then easily installed on the shelf, allowing for simple maintenance by removing and replacing individual rail sections without affecting the entire system

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The power supply rail acts as an intermediary between the power source and LED lamps. Instead of directly wiring lamps to the shelf or power source, the rail provides a standardized interface that simplifies both installation (by providing pre-configured power contacts) and maintenance (by allowing easy replacement of the rail or contact connectors)

Inventive Principle:
Principle #24Intermediary (Mediator)
