Modular Dry Erase Panels with Asymmetric Magnets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing erasable writing surfaces, such as dry erase boards, do not allow for seamless stacking or reconfiguration without disfiguring content when panels are overlapped or removed, and adhesive-backed notes generate unnecessary waste in collaborative activities.
Innovation Solution
A modular panel system with magnets affixed to the rear surface, allowing panels to be removably affixed to a magnetically attractable surface without disfiguring content, and enabling stackable or staggered configurations using strategically embedded and protruding magnets for alignment and retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If panels are stacked or overlapped to enable reconfiguration, then adaptability is improved, but content disfigurement occurs when panels are removed or repositioned
Solution Approach 1:
A release sheet is introduced as an intermediary layer between the dry erase panel and the magnetically attractable surface. This release sheet has a dry erase surface that contacts the panel and a magnetically attractable surface that contacts the magnetic surface, allowing the panel to be removably secured without direct magnetic contact that would cause content disfigurement during removal or repositioning
2Ease of operation
If adhesive-backed notes are used for collaborative activities, then ease of operation is improved, but waste is generated
Solution Approach 1:
The system enables recovery and reuse of the dry erase panel after use. The panel can be easily removed from the magnetically attractable surface using the release sheet mechanism, cleaned of its content, and reused for new collaborative activities, eliminating the waste associated with disposable adhesive notes
3Manufacturing precision
If magnets are embedded flush with the panel surface for stacking, then manufacturing precision is improved, but stacking retention is insufficient
Solution Approach 1:
The magnet is positioned asymmetrically within the panel thickness, with the first end protruding from the rear surface while the second end is embedded deeper into the panel. This asymmetric positioning creates a stronger magnetic field interaction with the magnetically attractable surface, providing sufficient stacking retention while maintaining manufacturing feasibility
