Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing track lamps face issues with poor plastic resilience of copper sheets, difficulty in obtaining electricity, and inconvenience in repeated installation due to insufficient resilience and deformation of copper sheets, especially in ultra-thin and ultra-narrow designs.
Innovation Solution
A track lamp design incorporating an elastic member between a power supply structure and a substrate, featuring a convex portion for electrical contact with a power transmission bar, allowing the power supply structure to move relative to the substrate under external pressure and return to its initial state, ensuring stable electrical connection without deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a compression spring structure is used to support the copper sheet, then the copper sheet can maintain contact with the copper bar for power supply, but the track lamp size increases and cannot meet ultra-thin and ultra-narrow requirements
Solution Approach 1:
The invention extracts the compression spring from the track lamp structure and relocates it to the track itself. The spring is embedded in a spring cavity within the track, allowing the copper sheet to be supported and pressed against the copper bar without increasing the lamp body size. This resolves the contradiction by separating the power support function from the lamp structure.
Solution Approach 2:
The invention introduces an elastic member as an intermediary between the copper sheet and the track. This elastic member transmits the supporting force from the track's spring structure to the copper sheet, enabling reliable electrical contact while keeping the lamp body compact and meeting ultra-thin design requirements.
2Device complexity
If the copper sheet relies on its own plastic deformation to support the track copper bar, then the structure remains simple, but the copper sheet has poor plastic resilience and cannot reliably maintain electrical contact
Solution Approach 1:
The invention extracts the support function from the copper sheet itself and transfers it to a dedicated spring structure within the track. This allows the copper sheet to focus on electrical conduction while the spring handles mechanical support, improving reliability without significantly increasing overall structural complexity.
Solution Approach 2:
The invention changes the material parameter from relying on copper sheet plastic deformation to using elastic deformation of the spring and elastic member. This parameter change enables reversible, reliable support that maintains electrical contact through multiple installation cycles without permanent deformation.
3Ease of operation
If the copper sheet is deformed during installation, then it can contact the copper bar, but the protrusion moves down after installation making repeated installation difficult
Solution Approach 1:
The invention inverts the traditional approach by having the track structure actively push the copper sheet into contact position via the spring and elastic member, rather than relying on the copper sheet's own deformation. This inversion allows the copper sheet to maintain its shape while still achieving reliable contact, enabling repeated installation.
Solution Approach 2:
The elastic member acts as a cushioning element that absorbs installation forces and gradually pushes the copper sheet into proper contact position. This beforehand cushioning prevents sudden deformation and protects the copper sheet's shape stability, allowing easy repeated installation.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design enables reliable and repeated installation by maintaining electrical contact stability while avoiding deformation of the power supply structure, facilitating easy assembly and disassembly.
Implementation Method 1
the elastic member is configured to generate elastic deformation in a case that the convex portion and the power transmission bar are pressed against each other, so that the convex portion and the power transmission bar are kept abutting against with each other

AI summary
The present application provides a track lamp, and belongs to the technical field of illumination. A track lamp comprises a track and an electrical connection apparatus in electrical contact with the track. The electrical connection apparatus comprises a base, an electricity receiving structure plugged into and secured to the base, and an elastic piece arranged between the base and the electricity receiving structure; the electricity receiving structure is provided with a protrusion for coming into electrical contact with a power transmission strip in the track, and the elastic piece is configured to elastically deform when the protrusion and the power transmission strip are pressed against one another, so that the protrusion and the power transmission strip continue abutting one another. In the present application, providing an elastic piece between the electricity receiving structure and the base allows the electricity receiving structure to move toward the base when subjected to external pressure, and when the external pressure disappears, allows the electricity receiving structure to move away from the base under the action of the elastic piece, thereby avoiding deformation of the electricity receiving structure, and achieving the repeated installation and use of the electrical connection apparatus.
