Solution Overview

Problem

Existing wall-hanging systems often damage walls upon removal, particularly when dealing with rigid objects like framed pictures, and require precise alignment and placement to ensure level and desired height, with limited options for adjustable and damage-free hanging solutions.

Innovation Solution

A releasable hanging system utilizing a combination of loop and hook fastener components, where a significant majority of male touch fastener elements are oriented to overhang a common direction, allowing for secure hanging and easy adjustment without damaging surfaces or objects, using a multiplicity of fibers and adhesive for secure engagement with minimal thickness and high shear resistance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If adhesive hanging systems are used to hang rigid objects on walls, then the objects can be removed without damage to most wall surfaces, but rigid objects cannot be flexed to peel them from the wall making removal difficult

Engineering Contradiction:
Improvewall damageVSAvoidremoval difficulty
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The fastening system is divided into two separate components: a loop fastener component that adheres to the wall and a hook fastener component that attaches to the object. This segmentation allows the loop component to be peeled from the wall without damage while the hook component remains attached to the rigid object, solving both the wall damage and removal difficulty problems.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The loop fastener component acts as an intermediary between the wall and the rigid object. It provides a flexible interface that can be peeled from the wall surface without damaging it, while still maintaining secure attachment to the rigid object through the hook-fastener mechanism.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If traditional adhesive hanging systems are used, then objects can be attached to walls, but precise alignment and placement are required to ensure level and desired height

Engineering Contradiction:
Improvehanging securityVSAvoidalignment precision
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system allows dynamic adjustment of the object's position and orientation after initial attachment. The modular fastener components enable users to reposition and realign the object easily without compromising the security of the hanging, eliminating the need for precise initial alignment.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If male touch fastener elements are oriented in multiple directions, then engagement flexibility is improved, but weight bearing capacity in a specific direction is reduced

Engineering Contradiction:
Improveengagement flexibilityVSAvoidweight bearing capacity
Core Design Contradiction:
Adaptability or versatilityVSStrength

Solution Approach 1:

The fastener system uses local quality by orienting the majority of male touch fastener elements in a single common direction to maximize weight bearing capacity in that direction, while a smaller number of elements are oriented in opposite directions to provide engagement flexibility for objects hanging at various orientations.

Inventive Principle:
Principle #3Local quality

AI summary

A releasable hanging system having a loop fastener component and a hook fastener component. The loop fastener component includes a flexible patch carrying a field of engageable fibers exposed on a front side of the patch and an adhesive on a back side of the patch. The hook fastener component includes a resin base carrying an array of male touch fastener elements. A significant majority of the male touch fastener elements each extend from the base to a distal tip to overhang the base in a single, common direction. The fastening system can be used to hang an object on a vertical surface such that the male touch fastener elements of the significant majority bear the weight of the object in a downward direction, and such that the significant majority of the male touch fastener elements are oriented so as not to inhibit lifting of the object in an upward direction.
