Coach Board with Removable Court Layer and Segmented Film
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional coach boards suffer from surface wrinkling and uneven visibility due to air entry between the transparent membrane and mounting board, and are limited to specific types of ball games because the court layer is unchangeable.
Innovation Solution
A coach board design featuring a foldable mounting board with an interlayer space for a removable attractive board and transparent film, allowing secure magnet attachment and easy switching of court layers for different games.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the transparent membrane is connected only at the perimeter edge to the mounting board, then the membrane can be easily installed, but air enters between the membrane and board causing surface wrinkling and uneven visibility
Solution Approach 1:
The transparent membrane connection is segmented into multiple regions: perimeter edge connection for easy installation, and additional internal connection points (such as connection ribs or adhesive regions) distributed across the membrane surface to prevent air pockets and wrinkling. This segmentation allows both easy installation and surface flatness to be achieved simultaneously.
2Device complexity
If the court layer is printed directly on the mounting board, then the structure is simple, but the court layer cannot be changed for different ball games
Solution Approach 1:
The court layer is transformed from a static printed pattern to a dynamic, replaceable component. The court layer is made as a separate removable element that can be dynamically swapped between different games, allowing the system to adapt to different requirements while maintaining a simple base structure.
Solution Approach 2:
The mounting board is designed with universal features such as standardized connection interfaces and multiple mounting positions that can accommodate different types of court layers for various ball games. This universality allows a single mounting board to support multiple court configurations.
3Reliability
If multiple coach boards are prepared for different ball games, then each board is optimized for its specific game, but the quantity of boards and storage space increase
Solution Approach 1:
A single mounting board is designed with universal capabilities to support multiple court layers for different ball games through standardized interfaces and interchangeable components. This multi-functionality eliminates the need for multiple dedicated boards, reducing quantity while maintaining game-specific optimization.
Solution Approach 2:
The coach board system is segmented into a permanent mounting board structure and interchangeable court layer components. This segmentation allows the core board to be reused across multiple games while only the court layers need to be changed, reducing the total number of boards required.
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 design ensures stable and flexible operation with clear court layer visibility and secure magnet attachment, enabling use across various ball games without surface wrinkling.
Implementation Method 1
The magnets can be put on the transparent membrane 70 at positions corresponding to the court layer 61 of the mounting board 60 and the magnets can be securely attracted and attached to the magnetic mounting board 60

AI summary
A coach board has a mounting board, a transparent film, an attractive board and a box. The transparent film is connected to the mounting board so as to form an interlayer space between the transparent film and the mounting board. The attractive board is removably inserted into the interlayer space between the transparent film and the mounting board and has a court layer. The court layer is attached to the attractive board, is visible via the transparent film and is protected by the transparent film. The box is mounted on the mounting board and receives multiple magnets inside. Therefore, a coach can instruct tactics to players easily by putting the magnets on the transparent film corresponding to the court layer of the attractive board.
