Spring-Elastic Support Pin Anchoring Lamp Socket
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lamp socket and holder systems, particularly for fluorescent and LED lamps, face challenges during mounting and dismounting due to imprecise insertion, low intrinsic stability, and the risk of accidental dropping or damage, as they require significant forces and lack efficient anchoring mechanisms.
Innovation Solution
A lamp socket with a spring-elastic support pin and a mounting dome that forms a movement path for anchoring and disengagement, allowing for easy insertion and self-acting removal by leveraging spring tension for secure anchoring and reduced dismounting force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional socket contacts with contact pins are used, then electrical connection is achieved, but insertion is imprecise and requires significant force
Solution Approach 1:
A guide pin acts as an intermediary element between the socket and holder during insertion. The guide pin aligns the socket contacts with the contact pins before final engagement, ensuring precise insertion without requiring excessive force. The guide pin's cylindrical shape provides mechanical guidance while the spring mechanism allows controlled movement during the alignment process.
Solution Approach 2:
The guide pin performs preliminary alignment action before the actual electrical contact engagement. By pre-positioning the socket contacts in the correct location relative to the contact pins, the system eliminates the need for high insertion forces and ensures accurate positioning before the final connection is made.
2Stability of the object's composition
If traditional lamp holders with mounting end stops are used, then mechanical support is provided, but dismounting causes sudden movement and risk of dropping
Solution Approach 1:
The spring-loaded guide pin creates a dynamic anchoring system that adapts during dismounting. As the user pulls the lamp, the spring gradually releases energy, providing controlled resistance that prevents sudden movement. This dynamic mechanism maintains lamp stability during normal use while enabling safe, controlled removal when needed.
Solution Approach 2:
The spring mechanism provides beforehand cushioning by storing elastic energy during insertion that is gradually released during dismounting. This cushioning effect prevents sudden movements and potential dropping by providing a controlled, progressive release of the anchoring force rather than an abrupt release.
3Reliability
If spring-elastic support pin with movement path is used, then secure anchoring and self-acting disengagement are achieved, but device complexity increases
Solution Approach 1:
The guide pin combines multiple functions into a single integrated component: it provides mechanical guidance during insertion, maintains electrical contact alignment, provides spring-loaded anchoring force, and enables controlled disengagement. By merging these functions into one element rather than using separate components, the system achieves reliable anchoring without proportionally increasing complexity.
Solution Approach 2:
The guide pin serves multiple purposes throughout the operational cycle: alignment guide, positioning reference, anchoring mechanism, and disengagement controller. This multi-functionality reduces the need for additional specialized components, maintaining reasonable complexity while achieving high anchoring reliability through the spring-elastic mechanism.

AI summary
A lamp socket including socket contacts for electrically contacting lamp holder contacts, the lamp socket including a mounting dome that is insertable into a lamp holder and includes a support pin that is linked in a spring elastic manner so that the support pin mechanically anchors the lamp socket in the lamp holder, wherein the mounting dome includes support surfaces which form a movement path along which the support pin is moveable, wherein the movement path displaces the support pin from an idle position in a first direction through a displacement section while building up a spring load during a relative movement of the lamp socket and the lamp holder, wherein the movement path returns the support pin through a return section towards an idle position of the support pin partially reducing the spring load during a relative movement of the lamp socket and the lamp holder.
