Solution Overview

Problem

Existing curtain holding devices require laborious installation and removal processes, making it time-consuming to hang and change curtains, especially for cleaning purposes, as they often necessitate the use of hooks or require dismantling the entire system.

Innovation Solution

A holding device with overlapping tabs or webs that can be easily hung on a curtain support, featuring a carrier band with specifically designed recesses that form hook-like elements when in a wavy shape, allowing for simple attachment and detachment via a Velcro system, enabling quick hanging and removal of curtains without complex hook insertion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional curtain rings or hooks are used to attach curtains to curtain rods, then the curtain can be securely fastened, but the installation and removal process becomes laborious and time-consuming

Engineering Contradiction:
Improvesecure fasteningVSAvoidinstallation and removal time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The holding device is divided into multiple independent holding elements (tabs or webs) that are distributed along the carrier band. Each holding element can independently engage with the curtain rod, allowing the curtain to be securely fastened at multiple points while enabling quick release by simply pulling the curtain downward, thus resolving the contradiction between secure fastening and easy removal

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Instead of using hooks that must be manually inserted into the curtain rod (complex installation), the invention uses tabs that automatically engage with the rod when the curtain is hung (simple installation). The tabs overlap the rod in the arranged state, creating a self-locking mechanism that requires no manual hook insertion, thereby reducing installation time while maintaining secure fastening

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

2Reliability

If individual holding elements are used that must be individually connected and hung, then the curtain can be securely attached, but the process becomes time-consuming and laborious

Engineering Contradiction:
Improvesecure attachmentVSAvoidhanging speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

Multiple holding elements are merged into a single integrated carrier band structure. The tabs or webs are continuously connected along the length of the band, forming one unified holding device that can be hung as a single unit rather than individual elements. This merging maintains secure attachment through distributed engagement points while dramatically increasing hanging speed by eliminating the need to individually connect and position each holding element

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The holding elements are pre-positioned and pre-shaped on the carrier band during manufacturing. The tabs are already formed in their engagement-ready configuration, so when the curtain is hung, the holding elements are immediately in the correct position and orientation to engage with the curtain rod. This preliminary preparation eliminates the need for manual adjustment and positioning during installation, thereby increasing productivity while ensuring reliable attachment

Inventive Principle:
Principle #10Preliminary action

3Reliability

If the entire holding device must be dismantled to remove the curtain for cleaning, then the curtain can be securely held, but the maintenance process becomes laborious

Engineering Contradiction:
Improvesecure holdingVSAvoidcurtain removal for cleaning
Core Design Contradiction:
ReliabilityVSEase of repair

Solution Approach 1:

The holding device incorporates a dynamic release mechanism where the tabs or webs can be easily disengaged from the curtain rod by applying downward force. The overlapping structure allows the tabs to flex and release from the rod during removal, then automatically re-engage when the curtain is hung. This dynamic behavior maintains secure holding during normal use while enabling easy curtain removal for cleaning without dismantling the entire device

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The curtain fabric is extracted as a separate removable component from the holding device. The carrier band with its integrated tabs remains on the curtain rod, while the curtain can be independently removed by pulling it downward to disengage the tabs. This separation allows the curtain to be taken out for cleaning while the holding device remains in place, maintaining secure holding capability for future installations

Inventive Principle:
Principle #2Taking out (Extraction)

4Reliability

If hook-shaped holding elements are used that engage in recesses, then the curtain can be effectively hung, but each element must be individually connected and hung

Engineering Contradiction:
Improveeffective hangingVSAvoidnumber of individual components
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Multiple hook-shaped holding elements are merged into a continuous carrier band structure with integrated tabs or webs. Instead of using separate discrete hooks that must be individually attached, the invention combines them into one unified band that presents multiple engagement points simultaneously. This merging maintains effective hanging through distributed tab-rod engagement while reducing device complexity by eliminating the need for multiple separate components and their individual connections

Inventive Principle:
Principle #5Merging (Combining)
