Solution Overview

Problem

Existing track assemblies are often complex and lack sufficient functionality, particularly in terms of selectively removable support assemblies that can engage tracks effectively.

Innovation Solution

A support assembly comprising first and second support members connected via a rod, allowing longitudinal sliding and rotation, with S-shaped contact members that engage the track to limit movement and include latches for selective engagement and removal, utilizing a biasing member to facilitate easy removal in one position and secure engagement in another.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If support assemblies are designed to be selectively removable from tracks, then ease of operation is improved, but structural integrity may be compromised

Engineering Contradiction:
Improveselective removal capabilityVSAvoidstructural integrity
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The support assembly incorporates movable support members that can slide longitudinally along the rod and rotate about it, transitioning between engaged and disengaged positions. This dynamic capability allows the assembly to be securely attached to the track when needed while enabling easy removal when not required, resolving the contradiction between structural integrity and ease of operation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The support assembly is divided into separate components including support members, contact members, and latches that can independently move and engage. This segmentation allows individual components to perform specific functions - contact members engage the track for structural integrity while latches provide selective retention - without compromising the overall strength or removal capability.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If track assemblies are designed with selective engagement capability, then adaptability is improved, but device complexity increases

Engineering Contradiction:
Improveselective engagement capabilityVSAvoidassembly structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Multiple functions are combined into integrated components. The contact members simultaneously provide longitudinal engagement with the track and lateral constraint through their S-shaped configuration. The latches combine retention functionality with positioning features, reducing the need for separate complex mechanisms while maintaining selective engagement capability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The support members serve multiple purposes: they provide structural support, enable longitudinal adjustment along the rod, allow rotational movement for engagement/disengagement, and incorporate latches for selective retention. This multi-functionality reduces the need for additional separate components, thereby reducing overall device complexity while maintaining adaptability.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Stability of the object's composition

If contact members are designed to limit longitudinal movement, then stability is improved, but ease of operation deteriorates

Engineering Contradiction:
Improvelongitudinal stabilityVSAvoidremoval difficulty
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The latches act as intermediary components between the support members and the rod ends. They provide the locking mechanism that limits longitudinal movement when engaged, yet can be easily released to allow removal. This intermediary element resolves the contradiction by providing stable engagement without permanently restricting operational flexibility.

Inventive Principle:
Principle #24Intermediary (Mediator)
