Solution Overview
Problem
Existing artificial Christmas tree trunk connectors suffer from uneven loading and potential bending or breaking due to the free play movement between the tapered and receiving ends, leading to instability and damage over time.
Innovation Solution
A connector system utilizing a sleeve with axially extending ribs for a slip fit with the first trunk section and circumferentially extending ribs for a press fit with the second trunk section, providing reinforcement and preventing movement or pivoting between the trunk sections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a tapered extending portion is inserted into a receiving end to connect trunk sections, then the trunk sections can be assembled together, but free play movement and pivoting occur leading to uneven loading and potential damage
Solution Approach 1:
A connector is introduced as an intermediary component between the first and second trunk sections. The connector features a receiving portion that accepts the extending portion of the first trunk section, and a body portion that fits into the receiving end of the second trunk section. This intermediary component eliminates free play movement and pivoting while maintaining ease of assembly through a simple insert-and-lock mechanism.
Solution Approach 2:
The connection system is divided into separate functional components: the extending portion of the first trunk section, the connector (comprising a receiving portion and body portion), and the receiving end of the second trunk section. This segmentation allows each component to be optimized for its specific function while simplifying the overall assembly process.
2Adaptability or versatility
If the extending portion pivots around the receiving end, then connection is achieved, but uneven loading occurs over time leading to bending and breaking
Solution Approach 1:
The connector acts as a mediator that prevents pivoting motion between trunk sections. The body portion of the connector fits tightly within the receiving end, creating a fixed connection that distributes loads evenly and prevents the structural damage caused by repeated pivoting and uneven loading.
3Reliability
If a sleeve with ribs is used to prevent movement between trunk sections, then stability is improved, but device complexity increases
Solution Approach 1:
The connector is segmented into distinct functional portions: a receiving portion with an opening for insertion, and a body portion that provides the stabilizing fit within the receiving end. This segmentation achieves stability through simple geometric forms rather than complex mechanisms, maintaining ease of manufacture and assembly.

AI summary
An artificial tree comprising a first trunk section and a second trunk section. The second trunk section can be configured to receive a portion of the first trunk section and can include a sleeve disposed proximate an end of the second trunk section. The sleeve can include a lower lip having an angled portion that can interact with a rolling protrusion disposed on the first trunk section. The rolling protrusion can rotate upon interaction with the angled portion of the lower lip to guide and assist the second trunk section to receive a portion of the first trunk section.
