Solution Overview

Problem

Existing curtain rod bracket systems lack mechanisms to securely attach to window blind brackets of varying depths and prevent curtain rod movement, failing to accommodate different window configurations without requiring structural modifications.

Innovation Solution

A curtain rod bracket attachment member composed of two expandable sections using an expandable washer and mating fastening member, allowing adjustable attachment to window blind head rails of varying heights without drilling or hammering, featuring a press fit retention mechanism to prevent curtain rod sliding.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing curtain rod bracket systems are used, then installation is simple, but they cannot securely attach to window blind brackets of varying depths and prevent curtain rod movement

Engineering Contradiction:

Improvesecure attachment and prevention of curtain rod movementVSAvoidaccommodation of varying head rail depths

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The bracket assembly includes adjustable components that allow the bracket depth to be modified according to different head rail depths. The bracket can be repositioned along the head rail to achieve secure attachment while maintaining the ability to prevent curtain rod movement through its press fit retention mechanism.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The bracket design allows for adjustment of its depth parameter to match varying head rail depths. By changing the bracket's effective depth through adjustment mechanisms, it can securely attach to different window configurations while maintaining reliable curtain rod retention.

Inventive Principle:

Principle #35Parameter changes

2Ease of manufacture

If existing curtain rod bracket systems are used, then installation requires minimal tools, but they require structural modifications such as drilling and hammering

Engineering Contradiction:

Improveinstallation process simplicityVSAvoidstructural modifications to head rail

Core Design Contradiction:

Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The bracket assembly is designed to be self-installing onto the head rail without requiring drilling or hammering. The press fit retention mechanism allows the bracket to secure itself to the head rail through friction and mechanical interference, eliminating the need for structural modifications while maintaining ease of installation.

Inventive Principle:

Principle #25Self-service

3Adaptability or versatility

If adjustable mechanisms are added to accommodate different head rail depths, then adaptability improves, but device complexity increases

Engineering Contradiction:

Improveaccommodation of different head rail heightsVSAvoidbracket assembly structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The bracket assembly is divided into segmented components that can be independently adjusted. This segmentation allows for modification of bracket depth without requiring complete redesign of the entire structure, thereby managing complexity while maintaining adaptability to different head rail configurations.

Inventive Principle:

Principle #1Segmentation

AI summary

A curtain rod bracket attachment member formed in two main sections which are slidably attached to each other. A first main section having an elongated section extending at one end to a first transverse retaining wall which is oriented perpendicular to the elongated section. A curtain rod retaining member extends at an opposite end of the elongated section to a curtain rod retaining section into which a curtain rod is placed and retained. A second main section includes a second transverse retaining wall and is slidably affixed to the elongated section of the main section to enable a distance between parallel first and second transverse retaining walls to be modified.
