Lamp Socket Retaining Clip with Top-Insertion Fastening Ring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing lamp designs for cooking devices, such as G9 lamps, have a complex assembly process due to the insertion of the holding bracket from below, which limits construction space and increases manufacturing costs and complexity.
Innovation Solution
The holding clip is integrated into a fastening ring that surrounds the socket holder, allowing the fastening ring to be inserted from the top, creating free space for improved ventilation and reducing the number of components needed, with the fastening ring forming a contour for the holding stone and incorporating feather legs that can be connected and separated for secure assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the retaining clip is inserted from below, then the lamp base can be anchored in the base receptacle, but the construction space on the underside is limited and manufacturing complexity increases
Solution Approach 1:
The retaining clip is inverted from the conventional below-insertion approach to a top-insertion approach. The holding leg is arranged on the upper side of the socket stone, and spring legs extend downward into the base receptacle, reversing the traditional insertion direction to simplify assembly and improve space utilization.
Solution Approach 2:
The retaining clip is integrated with the mounting ring into a single unified component. The holding leg connects to the mounting ring, and spring legs extend from it, combining two previously separate parts (retaining clip and mounting ring) into one integrated assembly that simplifies manufacturing and assembly processes.
2Reliability
If the retaining clip is inserted from below, then the lamp base can be secured, but free space for ventilation is reduced
Solution Approach 1:
By inverting the insertion direction of the retaining clip from below to above, the design creates free space on the underside of the socket. The spring legs extend downward into the base receptacle, leaving the lower area open for ventilation channels and heat dissipation pathways.
3Adaptability or versatility
If multiple separate components are used, then each component can be optimized independently, but manufacturing costs and assembly complexity increase
Solution Approach 1:
The retaining clip and mounting ring are merged into a single integrated component. The holding leg forms part of the mounting ring structure, and spring legs extend from it, creating one piece that performs multiple functions (mounting and retaining) simultaneously, reducing manufacturing steps and assembly operations.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design simplifies the assembly process, reduces manufacturing costs, and enhances ventilation, leading to a more reliable and efficient lamp operation, especially in high-temperature cooking environments.
Implementation Method 1
two spring legs of the retaining clip forming a receiving gap for the lamp base between them, each spring leg having a free end and a spring leg end connected to a holding leg and being seated in the base receptacle
