Hinged Communication Board Frame for Fast Replaceable Writing Sheets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication boards in hospitals and medical settings face issues with durability and ease of use, as their surfaces often become marred by misuse and it is difficult to quickly remove erasable materials from the underlying substrate sheets, leading to inefficiencies and costs.
Innovation Solution
A communication system with a frame having hingedly connected cover members and a functional member that supports an erasable sheet directly over a flexible media sheet, allowing for easy alignment and compression of the sheets against the substrate, along with optional features like lifting tabs and antimicrobial coatings, to enhance durability and usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If erasable boards are used in medical settings, then communication functionality is provided, but the surfaces become marred by misuse and inadequate erasing, reducing durability and appearance
Solution Approach 1:
The board is segmented into a permanent substrate base sheet and a separate removable erasable sheet. The substrate provides a durable, long-lasting base that resists damage, while the separate erasable sheet can be easily replaced if marred, resolving the contradiction between durability and surface damage resistance.
Solution Approach 2:
The substrate base sheet is designed with specific physical parameters (thickness, material properties) to provide enhanced durability and resistance to surface damage compared to traditional single-sheet boards, allowing the board to maintain appearance and functionality over extended periods.
2Ease of operation
If separate erasable material is placed over substrate sheet, then erasability is provided, but it becomes difficult to quickly remove the erasable material from the underlying substrate sheet
Solution Approach 1:
The erasable sheet is designed with preliminary features such as lifting tabs or release mechanisms that facilitate easy separation from the substrate. These preliminary design elements enable quick removal without requiring complex tools or procedures, resolving the contradiction between ease of operation and device complexity.
Solution Approach 2:
The erasable sheet is extracted as a separate, removable component from the substrate base sheet, allowing it to be independently handled, removed, and replaced. This separation enables quick sheet changes while maintaining a simple overall structure, addressing both ease of operation and device complexity.
3Duration of action of stationary object
If durable, long-lasting media sheets are used, then information conveyance durability is improved, but it is difficult to quickly change sheets when needed
Solution Approach 1:
The media system is segmented into a permanent durable substrate base sheet and a separate removable erasable sheet. The substrate provides long-lasting durability, while the separate erasable sheet can be quickly removed and replaced without compromising the substrate, resolving the contradiction between longevity and sheet change speed.
Solution Approach 2:
The substrate base sheet is preliminarily prepared with features such as slots, guides, or alignment mechanisms that facilitate quick insertion and removal of erasable sheets. This preliminary design enables rapid sheet changes while maintaining the durability of the underlying substrate, addressing both duration of action and time loss.

AI summary
A planar display communication board includes a frame having a plurality of sides, at least one of the plurality of sides includes a cover member hingedly connected to a functional member, the cover member having a raised position and a closed position, and the functional member including a slot and a shelf. A substrate base sheet is held within the slot of the functional member and an erasable sheet is positioned directly over a flexible media sheet and supported by the shelf. When the cover member is in the raised position, the erasable sheet and the flexible media sheet abut for alignment against shelf post extension; and when the cover member is in the closed position, the cover member compresses the erasable sheet and the flexible media sheet against the substrate base sheet away from at least one edge of the erasable sheet and the flexible media sheet.
