Adjustable Light Fixture Reflector Assembly for Post-Installation Beam Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light fixtures lack adjustable mechanisms that allow for easy reorientation or position changes after installation, limiting flexibility in light beam direction and distribution.
Innovation Solution
A light fixture design incorporating a first and second adjuster, featuring a fastening member and adjustment nut, and a second fastening member with an adjustment tab, enabling the reflector to pivot about a transverse or parallel axis, allowing for adjustable light beam angles without removing the fixture from its installed position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed mounting structure is used to secure the light fixture in the ceiling aperture, then the mounting reliability is improved, but the ability to adjust light beam direction after installation deteriorates
Solution Approach 1:
The patent applies the dynamics principle by transforming the static fixed mounting structure into a dynamic adjustable system. The reflector is made movable relative to the housing through adjustment mechanisms (adjustment members, fastening members, and slots) that allow the light beam direction to be changed after installation while maintaining secure mounting. This resolves the contradiction by enabling both reliable mounting and post-installation adjustability.
2Stability of the object's composition
If the reflector is fixed relative to the housing, then the structural stability is improved, but the ease of operation for adjusting light distribution deteriorates
Solution Approach 1:
The patent implements dynamics by creating a system that can transition between stable and adjustable states. The reflector is coupled to the housing through adjustment members that engage with slots and fastening members, allowing the structure to be stable during operation but easily adjustable when needed. The fastening members can be loosened to enable adjustment and tightened to secure the new position, maintaining structural stability while improving ease of operation.
Solution Approach 2:
The patent applies segmentation by dividing the coupling between the reflector and housing into separate functional components: adjustment members for movement, slots for guiding movement, and fastening members for securing. This segmentation allows the system to maintain structural stability through the fastening members while enabling easy adjustment through the adjustment members and slots, resolving the contradiction between stability and ease of operation.
3Adaptability or versatility
If adjustment mechanisms are added to allow reorientation of the reflector, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The patent reduces device complexity through segmentation by breaking down the adjustment function into simple, modular components: adjustment members that slide in slots, and fastening members that secure the position. Each component has a single, clear function, avoiding complex mechanisms while achieving the desired adaptability for adjusting light beam direction.
Solution Approach 2:
The patent uses the slot as an intermediary element between the adjustment member and the housing. The slot guides the movement of the adjustment member while maintaining a simple structural connection, enabling adjustability without requiring complex mechanisms. This intermediary approach simplifies the overall device complexity while achieving the adaptability goal.
