Adjustable Mounting Bracket for Classroom Electronic Whiteboard
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of electronic whiteboards into classrooms is hindered by the difficulty in mounting them alongside traditional teaching aids like blackboards, due to space constraints and the need for modifications that prevent repositioning and accommodate existing fixtures such as chalk trays.
Innovation Solution
A mounting system featuring a short bracket with adjustable components, including an upper and lower portion attached to the wall and a central portion that can be positioned in front of the chalk tray, allowing for flexible placement and attachment of the electronic whiteboard without requiring modifications to existing teaching aids.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the electronic whiteboard bracket is mounted directly onto the blackboard, then the whiteboard can be securely attached, but holes must be drilled in the blackboard preventing repositioning
Solution Approach 1:
The mounting system is divided into separate components: a wall-mounted bracket and a blackboard-clamping mechanism. This segmentation allows the bracket to be securely attached to the wall while the blackboard can be clamped without drilling, enabling both secure attachment and repositioning capability.
Solution Approach 2:
The patent introduces an intermediary clamping mechanism that attaches to the blackboard without drilling holes. This intermediary component bridges between the wall-mounted bracket and the blackboard, providing secure attachment while preserving the blackboard and enabling repositioning.
2Ease of operation
If the bracket extends all the way in front of the blackboard, then the electronic whiteboard can be mounted, but the bracket becomes large and cumbersome extending further from the wall
Solution Approach 1:
The bracket design utilizes vertical positioning to clear the chalk tray rather than extending horizontally in front of the blackboard. By positioning the bracket higher on the wall and using a vertical clearance approach, the system achieves mounting feasibility without requiring a large, cumbersome horizontal extension.
3Ease of operation
If the electronic whiteboard is positioned at the same level as the blackboard, then easy access is achieved, but the chalk tray is in the way of mounting
Solution Approach 1:
The mounting bracket is segmented into distinct functional portions: an upper portion attached to the wall above the blackboard, a lower portion that clears the chalk tray, and a central portion that extends forward to mount the whiteboard. This segmentation allows the whiteboard to be positioned at the same level as the blackboard for accessibility while the chalk tray remains undisturbed.
4Ease of manufacture
If the chalk tray is cut off to mount the electronic whiteboard, then mounting is achieved, but the whiteboard cannot be moved
Solution Approach 1:
The patent introduces a clamping mechanism as an intermediary that attaches to the blackboard without permanent modification. This intermediary component provides simple mounting while preserving the ability to reposition, eliminating the need to cut off the chalk tray.

AI summary
A mounting bracket allows an electronic whiteboard to be positioned in front of a blackboard. The mounting bracket is attached above the blackboard and extends in front of a portion of the blackboard. A lower portion of the mounting bracket abuts the front of the blackboard. The mounting bracket includes an adjustable portion at the lower end to adjust the distance between the blackboard and the mounting bracket. A standard mounting bracket for the electronic blackboard is attachable to the mounting bracket of the present invention. The height of the standard mounting bracket may be adjusted.
