Solution Overview

Problem

Existing holding systems are difficult to mount on a wall in a desired orientation without damaging the wall with holes, screws, or nails, and lack a simple and precise assembly method.

Innovation Solution

A holding system featuring a mounting frame with a self-adhesive device and positioning windows, allowing precise alignment using a leveling device, and a method involving adhering the frame to the wall, inserting fastening plates into the windows, and attaching object holders to the fastening plates for a secure and removable installation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If a holding system uses self-adhesive mounting without holes or screws, then the wall is not damaged, but the mounting precision and orientation control are insufficient

Engineering Contradiction:
Improvewall damageVSAvoidmounting orientation precision
Core Design Contradiction:
Object-affected harmful factorsVSManufacturing precision

Solution Approach 1:

The patent introduces a mounting frame as an intermediary component between the wall and the holding device. The frame includes positioning windows that guide the insertion of alignment tools, enabling precise orientation control without compromising the adhesive mounting method. This mediator allows traditional precision alignment techniques to work alongside modern non-invasive adhesive technology.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If the holding system uses adhesive strips only, then the structure is simple, but the mounting process is difficult to control for desired orientation

Engineering Contradiction:
Improvestructure simplicityVSAvoidmounting process ease
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The holding system is segmented into distinct functional components: a mounting frame for positioning, adhesive strips for attachment, and alignment tools for orientation control. This segmentation allows each component to perform its specific function optimally while maintaining overall system simplicity. The frame and adhesive strips remain structurally simple, while the alignment tools provide the necessary operational ease for precise mounting.

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If the holding system allows easy removal, then the adhesive can be pulled off, but the holding force during use may be insufficient

Engineering Contradiction:
Improveremoval easeVSAvoidholding force
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The adhesive system employs local quality differentiation through multi-strip configuration and selective placement. Multiple adhesive strips are distributed across the mounting frame at strategically located positions, creating localized high-strength bonding zones. This distribution provides both strong holding force during use and controlled removal capability, as the adhesive can be peeled back from edge points without compromising the entire bonding structure.

Inventive Principle:
Principle #3Local quality
