Solution Overview

Problem

Adjustable rods commonly used for supporting curtains and clothing on hangers face issues with jamming and require disassembly for repair, and lack the ability to be mounted both temporarily and permanently.

Innovation Solution

A dual-mounted end cap system with a locking mechanism that allows for both temporary and permanent mounting, featuring a lock assembly and end cap adjustment assemblies that ensure secure attachment to mounting walls without jamming.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a locking system is added to set the tubes relative to one another, then the rod length can be adjusted and fixed, but the locking system may become stuck requiring disassembly for repair

Engineering Contradiction:
Improverod length adjustmentVSAvoidlocking system jamming
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The locking system is divided into separate components: a lockable collar on one tube and corresponding locking features on the other tube. This segmentation allows the locking mechanism to be simpler with fewer moving parts, reducing the likelihood of jamming while still enabling adjustable rod length configuration.

Inventive Principle:
Principle #1Segmentation

2Stability of the object's composition

If end caps with friction pads are used to improve stability, then the rod is more secure when mounted, but the system cannot be permanently mounted to walls

Engineering Contradiction:
Improverod stabilityVSAvoidmounting flexibility
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The end caps are designed with dual functionality: they include friction pads for stable temporary mounting between walls, and integrated permanent mounting features (such as wall anchor receptacles or attachment mechanisms) that enable permanent wall attachment. This makes the same end cap component adaptable to both temporary and permanent installation scenarios.

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

3Strength

If the end caps apply pressure to mounting walls for secure attachment, then the rod is stabilized, but the system lacks permanent mounting capability

Engineering Contradiction:
Improveattachment strengthVSAvoidmounting option flexibility
Core Design Contradiction:
StrengthVSAdaptability or versatility

Solution Approach 1:

The end caps incorporate multiple attachment modes: a first mode using friction pads and pressure application for temporary secure attachment, and a second mode using integrated permanent mounting features (such as threaded inserts, wall anchor interfaces, or flange structures) for permanent wall mounting. This universal design provides both temporary and permanent mounting options within the same component.

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

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The system provides secure, jam-free operation and allows for both temporary and permanent mounting options, ensuring stability and ease of installation and removal.

Implementation Method 1

a lock sleeve that is flexible enough to expand and provide a sufficient frictional engagement with an inner surface of the outer tube to lock the tubes against relative movement

Methodology Applied
Scientific EffectFriction: Friction

Implementation Method 2

The end caps include pads which create friction and improve the stability of the adjustable rods when mounted to the walls

Methodology Applied
Scientific EffectFriction: Friction

AI summary

There is provided a dual mount end cap system for mounting a rod. The dual mount end cap system includes both a threaded system and a fastener system. This enables end caps of the system to be pre-mounted using a fastener and also adjusted using the threaded system. The fastener can extend through the dual mount end cap system. Alternatively, the threaded system can be used without the fastener system. There also is provided a stop system to prevent a locking system for an adjustable rod system to prevent the locking system from becoming stuck.
