Universal LED Bulb Fixing Device with Threaded Ring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional LED lamp fixtures are not universal, leading to inconvenience in replacing LED bulbs and resulting in resource waste due to non-separable components.
Innovation Solution
A fixing device comprising a cylindrical structural member with a screw thread and a ring-shaped fixing ring, allowing the LED bulb to be installed without a specialized socket, compatible with various lamp fixtures, and including a heat dissipation member for efficient thermal management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional specialized lamp sockets are used for LED bulbs, then the LED bulb can be fixed in the lamp fixture, but the lamp sockets have various specifications and types which are not universal, causing inconvenience to replace and waste of resources
Solution Approach 1:
The patent applies universality by designing a standardized screw thread structure on the outer peripheral surface of the structural member that can match with corresponding screw threads on different LED lamp fixtures. This allows a single LED bulb design to be universally installed across multiple fixture types, eliminating the need for specialized sockets for each bulb type and enabling easy replacement while reducing resource waste.
2Ease of manufacture
If LED lamp fixture and power supply and light source are designed integrally by patch processing, then the LED bulb can be fixed, but if any part is damaged it cannot be replaced separately, resulting in waste of resources and environmental pressure
Solution Approach 1:
The patent applies segmentation by dividing the LED lighting system into separable components: the structural member (housing), the light source assembly, and the power supply. These components are designed to be independently replaceable through the standardized fixing structure, allowing users to replace only the damaged component rather than the entire integrated unit, thereby reducing waste and improving ease of repair.
3Adaptability or versatility
If a fixing device with screw thread is used to install LED bulb, then the LED bulb can be universally installed, but the fixing device requires additional components (structural member, fixing ring)
Solution Approach 1:
The patent applies merging by integrating multiple functions into the structural member: it serves as the housing, contains the light source and power supply, provides the screw thread for fixing, and includes the through hole for wire passage. The fixing ring is designed as a simple complementary component that engages with the screw thread. This combination achieves universal installation capability while keeping the overall component count manageable through functional integration.

AI summary
A fixing device includes a structural member and a fixing ring. The structural member is a cylindrical structure having a first screw thread on its outer peripheral surface and the first screw thread matches with an LED lamp fixture. The structural member is opened at the top, and a through hole, a threaded hole, and a guide post are provided at the bottom of the structural member. An inner wall of the fixing ring is provided with a second screw thread matching with the first screw thread, and the structural member can be fixed into the LED lamp fixture by rotating the fixing ring.
