Tree Lamp Elastic Power Contacts for Stable Base Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing tree lamps suffer from unstable power connections between the lamp housing and base, leading to flickering or shutdown of the light-emitting body due to loose joints, affecting illumination quality.
Innovation Solution
The tree lamp design incorporates power connection contacts and electrically-conductive structures with elastic members that maintain contact and stability by compressing when the lamp housing is mounted on the base, ensuring a stable electrical connection through the use of elastic members that release forces to maintain contact even with slight loosening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the lamp housing is mounted on the base in a threaded connection manner, then the structural connection is achieved, but the contact between the power connection contact and the power connection structure becomes unstable when the joint is slightly loosened
Solution Approach 1:
The power connection contact is designed with elastic deformation capability, transforming from a static rigid connection to a dynamic adaptive connection. The elastic member allows the contact to automatically adjust its position and maintain stable electrical contact even when the threaded joint experiences slight loosening, resolving the contradiction between connection strength and electrical connection reliability.
Solution Approach 2:
The invention changes the physical state of the power connection contact from rigid to elastic by incorporating an elastic member. This parameter change enables the contact to deform under compression and maintain continuous electrical contact, ensuring reliable power transmission despite variations in mechanical connection tightness.
2Device complexity
If a rigid power connection contact is used, then the structure is simple, but the electrical connection becomes unstable when the joint loosens
Solution Approach 1:
The power connection contact incorporates an elastic member that changes its physical state from rigid to flexible. This allows the contact to deform and maintain stable electrical connection, improving power supply reliability while adding only minimal structural complexity through the elastic component.

Function Achieved in This Case
The solution provides a stable electrical connection between the lamp housing and base, preventing flickering and ensuring consistent illumination by maintaining contact through elastic forces, even with minor loosening, thus enhancing the illumination effect.
Implementation Method 1
each of the power connection contacts or each of the electrically-conductive structures comprises an elastic member, when the mounting portion is mounted in the mounting recess, the power connection contacts are in contact with the electrically-conductive structures, and the elastic members are compressed
