Track Light Elastic Contact Assembly for Repeatable Power Pickup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing track lights face challenges with copper sheets having poor resilience, leading to unreliable power transmission and difficulty in repeated installations, resulting in resource waste for existing lights that cannot be upgraded.
Innovation Solution
A track light design featuring a lamp with a substrate, an elastic structure detachably connected to the substrate, and a power obtain structure plugged and fixed on the substrate. The elastic structure includes a mounting post accommodated in a through hole of the substrate, with an elastic portion between the abutment portion and the substrate, allowing the power obtain structure to remain abutted with the track's power transmission strip despite external pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If copper sheets are used for power transmission in track lights, then power can be obtained from the track, but the copper sheets have poor resilience leading to unreliable power transmission and difficulty in repeated installations
Solution Approach 1:
The patent changes the material parameter from traditional copper sheet to an elastic contact structure with specific elastic modulus and geometric parameters (mounting post with elastic portion). This elastic structure can deform and rebound to maintain reliable electrical contact between the power transmission strip and contact portion, solving the resilience problem of copper sheets while enabling repeated installations.
2Productivity
If copper sheets are used for power transmission, then power can be obtained, but repeated installations are difficult resulting in resource waste
Solution Approach 1:
The patent segments the contact structure into detachable components: the elastic structure with mounting post that can be separated from the substrate, and the power obtain structure with contact portion. This segmentation allows the elastic structure to be reused across different installations by simply detaching and reattaching the contact portion, significantly improving installation repeatability and reducing resource waste.
Solution Approach 2:
The patent introduces dynamic characteristics through the elastic portion that can deform and rebound during installation and removal processes. The elastic structure dynamically adapts to mounting and dismounting operations, maintaining contact reliability during repeated installations while enabling easy separation when needed, thus improving both installation efficiency and repeatability.
3Reliability
If an elastic structure is introduced to improve contact reliability, then power transmission is maintained, but the device complexity increases
Solution Approach 1:
The patent applies local quality by introducing the elastic structure only at the specific contact point (mounting post with elastic portion) rather than throughout the entire substrate. The elastic portion is localized to where contact with the power transmission strip is needed, providing enhanced reliability only where required while keeping the rest of the substrate simple and maintaining overall structural simplicity.
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
The design ensures reliable power transmission by maintaining contact between the power obtain structure and the track's power transmission strip, allowing for repeated installations and extending the service life of the track lights, thereby avoiding resource waste.
Implementation Method 1
the elastic portion may be provided between the abutment portion and the substrate to generate elastic deformation in response to that the abutment portion and the power transmission strip are pressed against each other, so that the abutment portion and the power transmission strip remain abutted with each other
