Solution Overview

Problem

Existing bracket systems for mounting rod components, such as curtain guides, face issues with rod damage and instability, particularly due to loose connections and difficulty in detachment and replacement.

Innovation Solution

A bracket design that incorporates a damping element with a tailstock and damping head, allowing for secure mounting and easy detachment of rod components by utilizing a damping mechanism that prevents upward movement and requires sufficient force for disassembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If locking fixing is used to connect the bracket and rod component, then the connection stability is improved, but the rod component is easily damaged and cannot be detached conveniently

Engineering Contradiction:
Improveconnection stabilityVSAvoiddetachment convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The connection system is divided into two independent parts: the bracket with groove and the rod component with limiting parts. This segmentation allows the rod component to be replaced independently without damaging the bracket, resolving the contradiction between connection stability and detachment convenience.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The rod component is designed as a replaceable, shorter-lifetime part compared to the bracket. The limiting parts on the rod component can be worn or damaged and replaced independently, while the bracket remains intact. This resolves the contradiction by making the rod component disposable/replaceable while maintaining stable connection through the groove structure.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

2Reliability

If locking fixing is used to connect the bracket and rod component, then the connection stability is improved, but the device complexity increases due to additional fastening mechanisms

Engineering Contradiction:
Improveconnection stabilityVSAvoidfastening mechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The complex fastening mechanisms are extracted and replaced with a simple groove structure. The rod component's limiting parts interact with the bracket's groove through simple geometric constraints rather than complex fastening mechanisms, reducing device complexity while maintaining connection stability.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of using active fastening mechanisms to secure the rod, the design uses passive geometric constraints where the groove shape itself provides the locking function. The limiting parts on the rod naturally engage with the groove geometry, inverting the approach from active fastening to passive geometric locking.

Inventive Principle:
Principle #13The other way round (Inversion)

3Ease of operation

If a groove structure is used to allow rod replacement, then the detachment convenience is improved, but the rod component tends to loosen and has poor stability

Engineering Contradiction:
Improverod replacement convenienceVSAvoidconnection stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The groove and limiting parts are designed with asymmetric geometries that provide different functions: the groove shape allows easy insertion and replacement while the asymmetric limiting parts (triangular cross-section, spherical shape) prevent loosening and provide stable connection. This resolves the contradiction by using asymmetric design to simultaneously enable convenience and stability.

Inventive Principle:
Principle #4Asymmetry

Solution Approach 2:

The limiting parts are designed with specific geometric parameters (triangular cross-section with particular angles, spherical shape with specific diameter) that optimize the balance between ease of insertion and prevention of loosening. By carefully controlling these geometric parameters, both rod replacement convenience and connection stability are achieved.

Inventive Principle:
Principle #35Parameter changes

4Ease of operation

If the rod component is made detachable for regular cleaning and replacement, then the ease of operation is improved, but the connection stability deteriorates

Engineering Contradiction:
Improvedetachment convenienceVSAvoidconnection stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The groove structure is pre-designed with specific geometric features that automatically engage with the rod component's limiting parts during insertion. This preliminary design ensures that stable connection is established automatically when the rod is inserted, resolving the contradiction between detachability and connection stability.

Inventive Principle:
Principle #10Preliminary action
