Lamp Contact Members at Circumferential Edge for Compact Longitudinal Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lamps with small longitudinal dimensions face challenges in efficiently accommodating components like reflectors and electronic control means due to the need for compact designs, where the space behind the front side is underutilized for housing these components.
Innovation Solution
The contact members are positioned near the circumferential edge of the front side of the lamp, allowing the space behind to be used for a larger reflector and electronic control means, with a compact lamp holder design that surrounds the lamp, enabling a compact assembly with a small longitudinal dimension.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the contact members are positioned at the base part of the lamp, then the lamp can be fixed in the lamp holder, but the longitudinal dimension of the lamp increases
Solution Approach 1:
The contact members are repositioned from the longitudinal base area to the circumferential edge at the front side, utilizing the radial/directional space around the lamp's front face. This dimensional redistribution allows the lamp to maintain a compact longitudinal profile while preserving electrical contact functionality through lateral positioning of the contact members.
Solution Approach 2:
The lamp structure is segmented into distinct functional zones: the front side circumferential edge houses the contact members for electrical connection, while the longitudinal interior space accommodates the burner and reflector. This segmentation allows independent optimization of each zone, enabling compact longitudinal dimensions while maintaining reliable electrical contact through the separately positioned contact members.
2Length of moving object
If the space behind the front side is used for other parts, then the longitudinal dimension decreases, but the arrangement of components becomes more complex
Solution Approach 1:
Multiple functional components - the burner, reflector, and electronic control means - are merged into a single integrated lamp assembly with unified housing. The contact members are integrated into the front side circumferential edge structure, eliminating the need for separate mounting mechanisms and simplifying the overall component arrangement while achieving compact longitudinal dimensions.
Solution Approach 2:
The front side circumferential edge serves multiple functions: it provides structural support for the lamp housing, enables electrical contact through the contact members, and defines the mounting interface for the lamp holder. This multi-functionality reduces the need for additional components and simplifies the internal arrangement, allowing compact longitudinal design without increased complexity.
3Volume of moving object
If the contact members are positioned at the front side circumferential edge, then space utilization improves, but the contact reliability may be affected
Solution Approach 1:
The contact members at the front side circumferential edge are designed with localized structural features - such as resilient contact surfaces or spring-loaded configurations - that ensure reliable electrical contact specifically at this position. This local quality enhancement compensates for the non-traditional positioning, maintaining contact reliability while maximizing space utilization in the compact longitudinal design.

AI summary
A lamp comprising electric contact members (9,10) at the outside of the lamp for making contact with corresponding electric contact elements (21,22) in a lamp holder surrounding the lamp. The light radiation of the lamp is emitted from the front side (2) of the lamp, which front side (2) is substantially located in a plane perpendicular to the longitudinal direction of the lamp. The contact members (9,10) are located near the circumferential edge of said front side of the lamp.
