Tree Lamp Mounting Structure to Prevent Base Rotation and Shaking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Tree lamps in existing technologies suffer from loose connections between the lamp housing and base, leading to random rotation and shaking, which affects their reliability and stability.
Innovation Solution
The tree lamp design incorporates a mounting portion and recess with limiting structures, such as protrusions and grooves, to prevent rotation and shaking by abutting against each other at specific angles, ensuring secure attachment and detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the lamp housing is mounted on the base using bolts in a connected manner, then the structural simplicity is improved, but the reliability deteriorates due to loose connections causing rotation and shaking
Solution Approach 1:
The mounting portion and mounting recess incorporate asymmetric limiting structures (protrusions and grooves) that prevent rotation in specific directions. The first protrusions on the mounting portion fit into corresponding grooves on the base, creating an asymmetric geometric constraint that eliminates random rotation while maintaining a simple bolt-connected mounting approach.
Solution Approach 2:
The limiting structures act as intermediary elements between the mounting portion and mounting recess. These intermediate geometric features (protrusions fitting into grooves) mediate the connection by providing precise angular positioning and preventing excessive rotation, thereby enhancing reliability without adding complex mounting mechanisms.
2Ease of repair
If the mounting portion is detachably mounted in the mounting recess, then the ease of maintenance is improved, but the reliability deteriorates due to potential loosening and random angle changes
Solution Approach 1:
The detachable mounting maintains ease of assembly while incorporating asymmetric limiting structures that prevent random rotation. The first protrusions and grooves create a geometric lock that ensures consistent angular positioning upon reattachment, eliminating the reliability issues associated with loose detachable connections.
Solution Approach 2:
The limiting structures serve as intermediary geometric features that mediate between the detachable mounting requirement and joint stability. When the mounting portion is inserted into the mounting recess, the protrusions engage with the grooves to provide precise angular constraint, ensuring reliable connection while maintaining ease of detachment for maintenance.
3Reliability
If limiting structures are added to the mounting portion and recess, then the reliability is improved by preventing rotation, but the device complexity increases
Solution Approach 1:
The limiting structures utilize simple asymmetric geometric features (protrusions and grooves) rather than complex mechanical components. The first protrusions extending axially on the mounting portion engage with corresponding grooves on the base, providing effective rotation prevention through basic geometric constraints that add minimal complexity to the mounting structure.
Solution Approach 2:
The limiting structures modify the geometric parameters of the mounting portion and recess by adding axial protrusions and corresponding grooves. These parameter changes create angular constraints that prevent rotation while maintaining the overall simplicity of the bolt-connected mounting approach, adding only minimal structural complexity for significant reliability improvement.

AI summary
Provided in the present application is a tree lamp. The tree lamp includes a lamp housing and a base, where the lamp housing is configured to have a tree shape, and a lower end of the lamp housing is provided with a mounting portion; a top surface of the base is provided with a mounting recess fitted with the mounting portion, and the mounting portion is detachably mounted in the mounting recess; and the mounting portion and/or the mounting recess are/is provided with limiting structures, and when the mounting portion is mounted in the mounting recess, the limiting structures abut against the mounting portion or the mounting recess so as to limit rotation of the mounting portion relative to the mounting recess in at least one direction.
