Hook assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hook assemblies either damage walls when fixed with nails or have limited weight-bearing capacity due to variable adhesive strength when using pressure-sensitive adhesive tapes for easy separation.
Innovation Solution
A hook assembly design featuring a hook part with a hook member and an attachment part attached to a bonded surface using an adhesive tape, where the attachment part includes first and second attachment portions that allow for easy detachment by moving the hook part upward or downward, enabling secure adhesion and easy removal without wall damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a nail is driven into the wall to fix the hook, then the hook can firmly support heavy articles, but the wall surface is damaged and the user may suffer injuries
Solution Approach 1:
The patent replaces the mechanical nail-driven fixing system with a chemical adhesive bonding system. The adhesive tape with pressure-sensitive adhesive forms a chemical bond between the attachment part and the wall surface, eliminating the need for mechanical penetration and thus preventing wall damage and injury risks while maintaining supporting strength.
Solution Approach 2:
The patent introduces an adhesive tape as an intermediary element between the attachment part and the wall surface. This intermediary provides the bonding function, transferring the load from the hook to the wall through adhesive forces rather than mechanical interlocking, thereby avoiding direct contact and damage to the wall surface.
2Object-affected harmful factors
If a pressure sensitive adhesive tape is used to attach the hook, then the hook can be easily fixed without wall damage, but the weight of articles that can be supported is limited due to adhesive strength
Solution Approach 1:
The patent segments the hook into two separate parts: the hook part and the attachment part. The attachment part with adhesive tape remains on the wall to provide bonding and support weight capacity, while the hook part can be easily detached and reattached. This segmentation allows the adhesive to be optimized for strength while maintaining ease of installation and removal.
Solution Approach 2:
The patent creates a dynamic system where the attachment part can be repeatedly attached and detached from the wall surface. The adhesive tape maintains strong bonding during use but allows for controlled removal and reattachment, providing adaptability and reusability while supporting heavy articles throughout the attached state.
3Ease of operation
If the adhesive strength of the adhesive tape is lowered to enable easy separation, then the hook can be easily removed from the wall surface, but the weight of objects that can be hung is relatively limited
Solution Approach 1:
By separating the hook from the attachment part, the patent allows the adhesive tape to be optimized for strong bonding to support heavy objects, while the detachable hook part provides ease of operation. The attachment part remains firmly bonded to the wall, and only the hook part needs to be removed and reattached, maintaining both strength and ease of use.
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 design allows for easy detachment of the hook assembly from a bonded surface while maintaining sufficient adhesive strength, enabling the support of heavier objects without damaging the wall and allowing for reusability.

AI summary
A hook assembly is convenient for use and is easily detached from a bonded surface. The hook assembly includes a hook including a hook part (410) containing a hook member on which an object is hung to be supported thereby and an attachment part(420) attaching the hook part to a bonded surface, and an adhesive tape attaching the attachment part to the bonded surface, wherein the hook part (410) comprises hook-part hook having a protrusion (412), the attachment part (420) comprises an attachment-part hook (414). The hook-part hook being released from the attachment-part hook (414) when the protrusion (412) is pressed inwardly.
