Invertible Structure Track Mechanism for Controlled Inversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing invertible structures lack controlled inversion mechanisms and secure locking mechanisms, leading to difficulties in transitioning between upright and inverted orientations, especially in applications like artificial trees where easy storage and controlled movement are essential.
Innovation Solution
The implementation of a series of translational movements within a track system with multiple axes and a spring device, allowing for controlled reorientation of a longitudinal portion between upright and inverted positions, and a releasable mechanism with a latch for secure locking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional invertible structure is used without a track system, then the structure can be inverted, but the inversion process lacks control and locking is difficult
Solution Approach 1:
A track system serves as an intermediary mechanism between the longitudinal portion and the support portion, providing controlled guidance during inversion. The track with its slot and translational axes mediates the movement, ensuring controlled inversion while the releasable mechanism provides secure locking at desired positions
Solution Approach 2:
The system transitions from a static connection to a dynamic controlled movement system. The longitudinal portion can dynamically move between upright and inverted positions through the track, with the ability to be locked at intermediate positions, providing both control during transition and stability when positioned
2Reliability
If a simple connection mechanism is used, then the structure is easier to manufacture, but controlled inversion and secure locking cannot be achieved
Solution Approach 1:
The connection mechanism is segmented into distinct functional components: a track system with slot and translational axes for controlled movement, and a separate releasable mechanism with latch for locking. This segmentation allows each component to perform its specific function effectively while maintaining overall system manageability
Solution Approach 2:
The track system serves multiple functions: it guides the inversion movement, provides structural support, and works in conjunction with the releasable mechanism to enable both controlled motion and secure locking. This multi-functionality reduces the need for separate dedicated components for each function
3Ease of operation
If no translational movement mechanism is used, then the structure is simpler, but controlled inversion between upright and inverted orientations cannot be achieved
Solution Approach 1:
The longitudinal portion can be inverted and locked using the built-in track and releasable mechanism system that is integral to its design. The structure serves itself by having the inversion and locking functions built into the connection mechanism between the longitudinal portion and support portion, eliminating the need for external tools or complex additional mechanisms

AI summary
The disclosed invertible structures rely on combinations of translational movements to effect inversion. An exemplary invertible structure includes a track operable to be slidably coupled to at least two connectors of a longitudinal structure. The track may have a slot having a plurality of translational axes for translational movements of the connectors of the longitudinal structure that would effect the inversion of the longitudinal structure.
