Solution Overview

Problem

Existing track fasteners and adjustable attachments are not suitable for securely suspending heavy equipment from ceilings and walls without damaging the track surfaces or surrounding structures, and they lack the ability for quick and easy transverse adjustment.

Innovation Solution

A sturdy attachment device with a threaded stem and slug mechanism that securely immobilizes within a track's channel by forceful contact with flanges, allowing for easy rotation and adjustment, while avoiding damage to the track and surrounding structures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If conventional track fasteners and adjustable attachments are used to suspend equipment from ceiling tracks, then the installation can be achieved, but they are not suitable for heavy equipment and can damage track surfaces and surrounding structures

Engineering Contradiction:

Improveload-bearing capacityVSAvoiddamage to track surfaces

Core Design Contradiction:

StrengthVSObject-affected harmful factors

Solution Approach 1:

The patent introduces an intermediary mechanism (the clamp assembly with compression elements) between the suspension device and the track. This intermediary distributes the load forces across multiple contact points on the track flanges, preventing concentrated stresses that would damage the track surfaces while maintaining high load-bearing capacity for heavy equipment

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent changes the pressure distribution parameter by using a compression mechanism that applies distributed pressure through multiple flange contact points rather than concentrated point loads. This parameter change allows the system to handle heavy equipment weights while preventing surface damage through optimized force distribution across the track structure

Inventive Principle:

Principle #35Parameter changes

2Ease of operation

If adjustable track attachments are used to allow quick position changes, then ease of adjustment is improved, but they are designed for light components and cannot securely support heavy equipment

Engineering Contradiction:

ImproveadjustabilityVSAvoidload-bearing capacity

Core Design Contradiction:

Ease of operationVSStrength

Solution Approach 1:

The patent employs a dynamic adjustment mechanism where the threaded stem and clamp assembly can be quickly repositioned along the track and securely locked in place. The system transitions from a mobile state (easy adjustment) to a fixed state (high strength), allowing operators to achieve both ease of operation and load-bearing capacity through controlled dynamic behavior of the suspension device

Inventive Principle:

Principle #15Dynamics

3Reliability

If forceful contact is created with the rail elements to securely immobilize the stem, then reliability of suspension is improved, but damage to track surfaces may occur

Engineering Contradiction:

Improvesecure immobilizationVSAvoiddamage to track surfaces

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies beforehand cushioning by designing the clamp assembly to distribute compression forces through multiple flange contact points before the full load is applied. The gradual engagement of the threaded stem and clamp mechanism prevents sudden impact loads that could damage track surfaces, while still achieving reliable immobilization through distributed pre-compression forces

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

AI summary

A device for suspending equipment such as a lighting fixture or public address speaker from a ceiling mounted track (5) used to suspend a movable partition and including an extruded rail (4) defining a channel having a longitudinal slot opening (8) between flanges (9) projecting inwardly from opposite lateral walls(6) of the rail. The device comprises a threaded stem (13) capped by an enlarged head (14) passes through the slot opening (8) and is engaged by a lug (17) which cooperates with the head to forcibly bear against or capture one or more of the flanges. In an alternate embodiment of the invention the axial movement of the lug along the stem and the rotational movement of the head in reference to the slot are accurately limited for ease of alignment. The device can be quickly loosened to allow horizontal adjustment of the suspended structure along the rail.
