Light switch hook assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hooks for hanging articles on walls often damage the surface by puncturing it during installation or leave adhesive residue when removed, which can affect paint or finishes.
Innovation Solution
A light switch hook assembly that uses a fastener originally intended to secure a light switch plate to an electrical box, allowing the hook to be attached without puncturing the wall and without leaving residue, with a cover to hide the fastener head.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a nail, screw, or fastener is used to secure the hook to the wall, then the hook is securely attached, but the wall surface is punctured and damaged
Solution Approach 1:
The light switch plate serves as an intermediary carrier that is already securely mounted to the wall through existing fasteners. By attaching the hook to the light switch plate rather than directly to the wall, the solution achieves secure attachment while avoiding additional wall punctures and damage.
2Object-affected harmful factors
If an adhesive strip is used to secure the hook to the wall, then the wall surface is not punctured, but adhesive residue is left on the wall when the hook is removed
Solution Approach 1:
The light switch plate acts as a mediator between the hook and the wall. The hook is attached to the light switch plate using mechanical fasteners (screws or nails), which are then concealed by a cover. This approach avoids both wall punctures and adhesive residue, as the fastening system is contained on the light switch plate itself rather than involving the wall surface directly.
3Strength
If a fastener is used to attach the hook to the light switch plate, then the hook is securely mounted, but the fastener head is visible and aesthetically unpleasing
Solution Approach 1:
The cover serves as an aesthetic intermediary that conceals the fastener head while maintaining the structural integrity of the attachment. The cover is positioned over the fastener head, hiding it from view while allowing the fastener to remain in place and provide secure mounting of the hook to the light switch plate.

AI summary
A light switch hook assembly including a light switch plate and a hook extending outwardly therefrom. A fastener is inserted through an aperture defined in the hook and then into a hole defined in the light switch plate. The end of the fastener is subsequently inserted into an opening defined in a light switch mounted within an electrical connector box. The light switch plate may already be installed on a wall. In this instance, a fastener is removed from this pre-existing light switch plate, the hook is positioned against the plate, and the fastener is inserted through the aperture in the hook, through the hole from which the fastener was previously removed, and into the opening in the light switch. A cover may be engaged with the hook to cover the head of the fastener. An article may be hung on the hook.
