Rotatable Light Fixture Mounting Base With Electrical Contacts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional light fixtures are difficult to adjust in terms of rotation, mounting, and aiming without breaking electrical contact from the junction box and/or connecting base, limiting flexibility and ease of installation.
Innovation Solution
A rotatable light fixture system with a mounting base that maintains electrical connectivity through rotational exposed contacts and a mechanical locking mechanism, allowing 360-degree rotation while securing the light fixture housing to the mounting base using cam locks and retention members, ensuring continuous power supply and easy installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional light fixtures are wired directly to a junction box, then electrical connectivity is established, but adjustment of rotation and mounting orientation requires breaking electrical contact
Solution Approach 1:
The invention divides the electrical connection system into two independent parts: a fixed base with electrical contacts and a rotatable fixture with corresponding contacts. This segmentation allows the fixture to rotate independently while maintaining electrical connection through the interface between the two segments, resolving the contradiction between adjustability and connectivity.
Solution Approach 2:
The base acts as an intermediary component between the junction box and the rotatable fixture. It provides a stable electrical interface with rotational contacts that maintain continuity during rotation, serving as a mediator that enables both fixed electrical connection and movable fixture positioning.
2Adaptability or versatility
If light fixtures are securely mounted to maintain electrical contact, then reliability is improved, but flexibility for rotation and repositioning is reduced
Solution Approach 1:
The invention transitions from a static, fixed connection to a dynamic system where the fixture can rotate within a defined range while maintaining electrical contact. The rotational mechanism with spring-loaded or sliding contacts enables continuous movement without compromising the stability of the electrical connection.
Solution Approach 2:
The invention merges two previously separate functions into a single integrated base: providing both secure electrical connection and enabling rotational movement. The base combines electrical contacts with mechanical support structures that accommodate rotation, eliminating the need for separate mounting and electrical components.
3Ease of manufacture
If light fixtures require breaking electrical contact for adjustment, then manufacturing simplicity is maintained, but installation complexity and time increase
Solution Approach 1:
The base is pre-configured with electrical contacts and mounting features during manufacturing. This preliminary preparation allows the fixture to be quickly installed and adjusted without complex wiring operations, reducing installation time while maintaining manufacturing simplicity through standardization of the base component.
