Rotating Fastening Element for LED Street Light Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional LED street lights are cumbersome and heavy, making their assembly with light sockets time-consuming and inconvenient due to the need for multiple screws, which complicates the process and affects energy efficiency.
Innovation Solution
A rotatable fastening element with second fastening portions is integrated into a ring groove on a base, allowing for easy attachment and detachment of the LED light source by rotating the fastening element between a fastening and releasing position, reducing the need to rotate the entire LED light body during assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If multiple screws are used to lock the LED light with the light socket, then the connection strength is improved, but the assembly time and operational convenience deteriorate
Solution Approach 1:
The fastening function is segmented from the main LED light body and embodied in a separate rotatable fastening element. This allows the LED light to be quickly positioned while the fastening element provides the secure connection through rotation, separating the positioning function from the fastening function to reduce assembly time while maintaining connection strength
Solution Approach 2:
The fastening mechanism transitions from static multiple screws to a dynamic rotatable fastening element with movable clamping portions. The clamping portions can dynamically adjust their position through rotation, providing both quick assembly and secure fastening without requiring multiple static fastening points
2Reliability
If multiple screws are used to lock the LED light with the light socket, then the connection reliability is improved, but the ease of operation deteriorates
Solution Approach 1:
Multiple fastening functions are merged into a single rotatable fastening element with multiple clamping portions. This unified structure provides reliable multi-point fastening through rotation while simplifying the operation to a single rotational motion, improving ease of operation while maintaining connection reliability
Solution Approach 2:
The rotatable fastening element with elastic clamping portions provides self-adjusting fastening capability. As the fastening element rotates, the elastic clamping portions automatically engage with the LED light's fastening portions, creating a self-servicing fastening mechanism that ensures reliable connection without requiring precise manual alignment or multiple fastening steps
3Temperature
If the LED light is designed to be bulky for better heat dissipation, then the thermal management is improved, but the device complexity and assembly difficulty worsen
Solution Approach 1:
The fastening system uses a dynamic rotatable fastening element that can accommodate the bulky LED light structure. The rotation mechanism allows the fastening portions to engage with the LED light's mounting structure regardless of its size or heat dissipation features, simplifying assembly despite the increased device complexity from thermal management requirements

AI summary
An assembling structure includes a base, an assembling body and a fastening element. The base has a ring groove. The assembling body includes at least two first fastening portions. The fastening element is disposed inside the ring groove and can be rotatably installed on the base. The fastening element includes at least two second fastening portions. The fastening element can rotate relative to the base and has a fastening position and a releasing position. When the fastening element is at the fastening position, the two first fastening portions are fastened with the two second fastening portions respectively. When the fastening element is at the releasing position, the two first fastening portions are detached from the two second fastening portions respectively.
