Artificial Tree Trunk Connection System with Anti-Twist Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing artificial Christmas tree trunk section connection systems face challenges in secure mechanical coupling and electrical connection, often requiring rotational alignment, which can lead to wobbling and damage to ornaments or the tree during assembly and disassembly.
Innovation Solution
A trunk connection system featuring a male end with angled guiding surfaces and a female end with a guiding protrusion, allowing for secure mechanical and electrical coupling without rotational alignment, using a power distribution subsystem with male and female electrical connectors to facilitate easy assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If trunk sections are designed with tapered ends for mechanical connection, then assembly is simplified, but rotational stability deteriorates causing wobbling
Solution Approach 1:
The patent applies asymmetry by introducing a guiding protrusion on one trunk section and a corresponding guiding channel on the other, creating an asymmetric geometric relationship that prevents rotational misalignment while maintaining easy assembly through the tapered connection design
2Manufacturing precision
If electrical connectors require rotational alignment, then electrical connection precision is improved, but assembly complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-aligning the electrical connectors through the guiding protrusion and channel mechanism before final connection, so that the connectors are automatically positioned correctly during the assembly process without requiring separate alignment steps
3Stability of the object's composition
If trunk sections are tightly fitted to prevent wobbling, then rotational stability is improved, but assembly ease deteriorates
Solution Approach 1:
The patent applies segmentation by separating the connection functions into distinct components: the tapered ends provide easy mechanical insertion, while the guiding protrusion and channel provide rotational alignment and stability, allowing each function to be optimized independently
