Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lighting systems face limitations in the alignment and movement of emitting units due to electrical connection cables, which restrict pivoting beyond 360°, cause cable deformation, and introduce stiffness, especially for small luminaires.
Innovation Solution
A wireless pivoting and tilting contact system for emitting units, utilizing a cylindrical contact and ring contact mechanism that allows rotation and tilting without cables, enabling flexible movement and electrical connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an electrical connection cable is used to connect the emitting unit to the support bracket, then electrical connection is established, but the cable restricts the alignment movement and pivoting of the emitting unit
Solution Approach 1:
The patent extracts and eliminates the cable from the system by implementing a cable-free electrical connection. The emitting unit is equipped with electrical contacts that engage with corresponding contacts on the support bracket, allowing electrical power and signal transmission without any physical cable connecting the moving emitting unit to the stationary support bracket.
Solution Approach 2:
The patent replaces the mechanical cable-based electrical connection system with a contact-based electrical connection system. Instead of using a flexible cable that physically connects the emitting unit to the support bracket, the invention uses electrical contacts on both components that establish electrical connection through direct contact or proximity coupling, eliminating the mechanical constraints of the cable.
2Reliability
If a cable is used for electrical connection, then electrical power can be transmitted, but the cable can deform severely and frequently leading to breakage and contact failures
Solution Approach 1:
The patent removes the cable entirely from the electrical connection path. By using fixed electrical contacts on the support bracket and corresponding contacts on the emitting unit, the system eliminates the flexible cable that is prone to deformation and breakage, thereby improving the durability and reliability of the electrical connection.
Solution Approach 2:
The patent creates a dynamic electrical connection system where the emitting unit can move freely while maintaining electrical contact. The electrical contacts are designed to maintain reliable connection during movement, with the contacts on the emitting unit engaging with or approaching the contacts on the support bracket dynamically as the emitting unit moves to different positions.
3Reliability
If a cable is used for electrical connection, then power transmission is enabled, but the cable introduces additional stiffness which is undesirable for very small luminaires
Solution Approach 1:
The patent extracts the cable from the system, eliminating its weight and stiffness. The emitting unit, especially for very small luminaires, is connected electrically through contacts that do not add the mechanical burden of a cable, allowing the luminaire to maintain its desired flexibility and lightweight characteristics.
