Solution Overview
Problem
Existing power supply solutions for displays, such as LED lighting, are hindered by excessive wires that complicate installation, increase costs, and pose safety risks due to exposed conductive strips which are not waterproof.
Innovation Solution
A power supply device featuring a strip-shaped power supply cavity with flexible conductive strips and a sliding power taking head, allowing for adjustable and waterproof power distribution, reducing wire clutter and enhancing safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If fixed-length wires are used for power supply, then installation is simple initially, but the wires cannot accommodate shelf height adjustments and must be removed and reinstalled
Solution Approach 1:
The patent applies the dynamics principle by replacing fixed-length wires with flexible conductive strips that can dynamically adapt to different shelf positions. The flexible conductive strip can be stretched or bent as the shelf layer moves up or down, eliminating the need to remove and reinstall wires during height adjustments.
Solution Approach 2:
The patent uses a flexible conductive strip as a thin film structure that provides electrical connection while accommodating movement. This flexible strip can deform elastically to maintain contact between the power supply terminal and the moving shelf, solving the limitation of rigid fixed-length wires.
2Adaptability or versatility
If multiple wires are used for power supply to different shelves, then each shelf can be powered independently, but it creates wire clutter and increases installation complexity
Solution Approach 1:
The patent merges multiple separate wire connections into a single integrated flexible conductive strip system. The strip continuously connects the power supply terminal to various shelf positions along its length, eliminating the need for multiple discrete wires and reducing overall system complexity.
Solution Approach 2:
The flexible conductive strip serves multiple functions simultaneously: it provides electrical power, accommodates shelf movement, and adapts to different shelf configurations. This universal component replaces multiple specialized wires, simplifying the overall power distribution system.
3Ease of manufacture
If exposed conductive strips are used on power supply rails, then power distribution is achieved, but waterproofing cannot be ensured
Solution Approach 1:
The patent covers the exposed conductive strip with a flexible insulating film that provides waterproof protection. This thin film enclosure maintains the electrical functionality while protecting the conductive elements from moisture and environmental damage, ensuring reliable operation in various conditions.
