Flexible Magnetic Spray Can Holder That Prevents Surface Scratching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of flexible and magnetic spray can holders that can securely hold spray cans and attach to metal surfaces without scratching or maring the surface, and existing holders do not provide adequate organization or grip.
Innovation Solution
A flexible magnetic spray can holder made of thermoplastic elastomer with strong neodymium magnets and steel-wrapped magnets for secure grip, featuring a clip for the cap, a ledge to prevent sliding, and a mounting hole for peg boards, ensuring secure attachment to metal surfaces without damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If rigid materials are used for spray can holders, then structural strength is improved, but the surface may be scratched or marred
Solution Approach 1:
The holder body is constructed from flexible material that can conform to the curvature of spray cans, providing a soft contact surface that prevents scratching while maintaining structural integrity through elastic deformation rather than rigid support
Solution Approach 2:
The holder combines flexible material with magnetic elements to create a composite structure that provides both gentle surface contact and strong holding force, separating the functions of structural support and surface interaction
2Ease of manufacture
If non-magnetic materials are used for spray can holders, then manufacturing simplicity is improved, but attachment to metal surfaces is not achieved
Solution Approach 1:
The holder is designed with dual functionality: it can hold spray cans through magnetic attraction and attach to metal surfaces (such as tool chests or refrigerators) through the same magnetic mechanism, eliminating the need for separate mounting hardware
Solution Approach 2:
Magnetic forces replace traditional mechanical attachment methods such as screws, clips, or adhesives, allowing the holder to securely attach to metal surfaces without complex assembly or surface modification
3Ease of manufacture
If weak magnets are used in the holder, then manufacturing cost is reduced, but grip strength on spray cans is insufficient
Solution Approach 1:
Steel strips or steel-backed magnets are used as intermediaries to concentrate and amplify the magnetic field, allowing weaker or more cost-effective magnets to achieve strong holding forces through magnetic flux concentration in the steel pathway
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 flexible magnetic spray can holder effectively organizes spray cans by securely gripping them with strong magnets and attaching to metal surfaces without scratching, providing a stable and versatile storage solution.
Implementation Method 1
The front wall has one or more magnets for engaging and holding a spray can
Implementation Method 2
The back wall has one or more magnets for attaching the holder to a metal surface
