Track Assembly Lever for Removable Support Member Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Track assemblies are often complex to use and assemble, and lack configurations for removably connecting components or seats, which complicates their installation and operation.
Innovation Solution
A track assembly design featuring a lever that selectively engages tracks to limit movement, with a tooth and hooked portion to restrict longitudinal and vertical movement, allowing for adjustable positions to facilitate easy assembly and disassembly of support members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If track assemblies use multiple components and complex connection processes, then they can achieve secure engagement and movement control, but they become complex to use and assemble
Solution Approach 1:
The lever combines multiple functions into a single component: it provides both longitudinal movement restriction through the tooth engaging with the second track and vertical movement restriction through the hooked portion engaging with the first track. This merging of functions reduces the number of separate components needed while maintaining secure engagement.
Solution Approach 2:
The lever serves multiple purposes simultaneously: it acts as a locking mechanism for longitudinal movement, a locking mechanism for vertical movement, and a selective engagement device that can be positioned in different states (first position for longitudinal restriction, second position for vertical restriction). This multi-functionality simplifies the overall assembly while maintaining reliability.
2Stability of the object's composition
If track assemblies are designed with fixed connection methods, then they provide stable support, but they lack adaptability for removable connection of components or seats
Solution Approach 1:
The lever is designed to be movable between a first position and a second position, allowing the track assembly to dynamically change its engagement characteristics. In the first position, it restricts longitudinal movement; in the second position, it restricts vertical movement. This dynamic positioning provides both stability when engaged and adaptability for removal or reconfiguration.
Solution Approach 2:
The connection system is segmented into distinct functional elements: the lever, the tooth, the hooked portion, the first track with wing, and the second track with aperture. This segmentation allows each element to perform its specific function while enabling the overall system to be easily assembled and disassembled by simply moving the lever between positions.

AI summary
A track assembly includes a first track, a second track, and a support member. The second track may be disposed substantially in the second track. The lever may be configured to selectively engage the first track and/or the second track to limit longitudinal movement and/or vertical movement of the support member relative to at least one of the first track and the second track. The lever may include a tooth. The tooth may be configured to contact the second track to limit longitudinal movement of the support member along the second track. The tooth may be configured to engage an aperture in the second track. The tooth may be substantially planar and/or may extend in a transverse-vertical plane. The lever may include a hooked portion. The hooked portion may be configured to limit vertical movement of the support member.
