Rotating Spring Elastic Assembly for Down Lamp
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional down lamp assembly requires two-handed operation and can lead to unbalanced stress, causing springs to pop out of the Halo barrel, potentially deforming or fracturing it during single-sided assembly.
Innovation Solution
An elastic assembly with a rotating cavity and a spring that allows a movable end to flip between 0° to 90°, featuring a limiting assembly with a fixing seat and a limiting member, and a spring with a rotating connection portion, enabling easier assembly and reducing stress on the Halo barrel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional two-handed assembly operation is used to connect springs with Halo barrel, then assembly reliability is improved, but assembly complexity and time consumption increase
Solution Approach 1:
The spring is designed with dynamic rotation capability, allowing the movable end to rotate 0-90 degrees relative to the fixing end. This dynamic adjustment enables the spring to adapt to different assembly positions and orientations, facilitating single-handed operation while maintaining reliable connection with the Halo barrel
Solution Approach 2:
The invention changes the angular parameter of the spring by allowing rotation from 0 to 90 degrees. This parameter change enables the spring to be installed at different angles, making the assembly process more flexible and easier to perform with one hand while ensuring proper engagement with the Halo barrel
2Productivity
If single-sided assembly is used to connect springs, then assembly time is reduced, but stress balance deteriorates causing springs to pop out and Halo barrel deformation
Solution Approach 1:
The rotatable spring design allows dynamic adjustment of the spring angle during single-sided assembly. The spring can rotate to the optimal angle (0-90 degrees) to achieve balanced stress distribution on the Halo barrel, preventing the spring from popping out while maintaining high assembly speed
Solution Approach 2:
By changing the angular parameter of the spring through rotation, the invention enables single-sided assembly to achieve stress balance. The movable end can be positioned at different angles relative to the fixing end, allowing the spring to engage the Halo barrel in a way that distributes stress evenly, thus preventing deformation and pop-out issues

AI summary
Disclosed are an elastic assembly and a down lamp. The down lamp includes a lamp body and an elastic assembly. The elastic assembly includes a limiting assembly and a spring. The limiting assembly is provided with a rotating cavity. The fixing end of the spring is rotatably embedded in the rotating cavity, so that a flip angle of a movable end of the spring ranges from 0° to 90°. The present disclosure can enlarge the adjustable angle of the spring and reduce the assembly difficulty of the down lamp.
