Solution Overview
Problem
Existing attachment methods for vertical surfaces, such as picture hooks, are not suitable for objects that need to be frequently moved, as they become unstable and can fall due to pin loosening, and alternative methods like adhesive hooks or screws cause damage to the surface.
Innovation Solution
A modular mounting device with an adhesive pad and pin arrangement, where the pin carries the weight and the adhesive pad prevents movement, allowing for reliable attachment of objects that may be moved, and is designed to support up to 20 kg per hook.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a picture hook with pin is used to attach an object to a vertical surface, then the object can be mounted, but the pin becomes loose and the hook becomes unstable when the object is frequently moved
Solution Approach 1:
The mounting device is divided into separate functional components: a bracket that remains fixed to the wall, and a removable cover that attaches objects. The bracket contains pin apertures that receive pins inserted into the wall, while the cover snaps onto the bracket. This segmentation allows the permanent pin attachment to remain stable while the removable cover enables easy object changes without disturbing the pin configuration.
Solution Approach 2:
The device transitions from a static, fixed attachment system to a dynamic system where the cover can be easily attached and detached. The bracket maintains a fixed position with pins embedded in the wall, while the cover provides dynamic reconfigurability through snap-fit attachment and removal, enabling frequent object changes without compromising the stability of the underlying pin structure.
2Ease of operation
If adhesive hooks are used to attach objects to vertical surfaces, then the attachment is easy to install and remove, but the adhesive bonding is insufficient for heavy objects or causes damage to the surface when removed
Solution Approach 1:
The system separates the heavy-duty permanent mounting function (bracket with pins in wall) from the easy-attachment removable function (snap-fit cover). The bracket provides strong, damage-free permanent attachment through pins that carry the full load, while the cover offers easy installation and removal without requiring adhesive, thus combining the strengths of both approaches.
Solution Approach 2:
The bracket acts as an intermediary between the wall and the removable cover. Instead of directly bonding the cover to the wall with adhesive (which has insufficient strength), the bracket provides a robust intermediate structure that receives pins in the wall and accepts the cover through snap-fit attachment, thereby enabling strong holding capacity while maintaining ease of operation.
3Strength
If screws with fixing anchors are used to attach hooks to vertical surfaces, then the connection is strong, but permanent damage is caused to the wall requiring repair
Solution Approach 1:
The harmful element of screw threads that cut and damage the wall material is extracted and replaced with pins that simply press against the wall surface. The pins provide equivalent or superior holding strength without the cutting action of screw threads, thereby eliminating the need for wall repair while maintaining strong connection.
Solution Approach 2:
Instead of using expensive screw anchors that permanently damage the wall, the invention uses simple, inexpensive pins that can be cleanly removed and reused. The pins serve their purpose of providing strong attachment without creating permanent damage, effectively replacing the need for disposable screw anchors with reusable, damage-free alternatives.
4Strength
If picture hooks are used to mount objects, then light objects can be held, but the pins become loose quickly when objects are frequently moved
Solution Approach 1:
The system segments the functions of permanent attachment and removable attachment. The bracket with pins provides stable, damage-free permanent attachment to the wall, while the removable cover handles the objects. This segmentation prevents the pins from being subjected to repeated insertion and removal forces that cause loosening, while still enabling frequent object changes through the removable cover mechanism.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a stable and damage-free attachment method for objects that need to be frequently moved, supporting significant weight without causing permanent damage to the mounting surface.
Implementation Method 1
an adhesive pad with pin arrangement is advantageous whereby the pin or pins carries the weight of an object to be mounted and the adhesive pad prevents movement of the pin or pins with respect to the mounting surface
