Reusable Drawing Board With Replaceable Sealed Card Envelopes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drawing game boards are typically single-use, leading to waste and a need for a reusable board that maintains security features.
Innovation Solution
A reusable drawing game board with sequentially numbered pockets and sealed envelopes for playing cards, allowing reuse by replacing envelopes after each game.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single-use drawing game board is used, then security features are maintained, but waste is generated and cost-effectiveness deteriorates
Solution Approach 1:
The game board is divided into two functional segments: a reusable backing member with pocket structures and a replaceable set of sealed envelopes. This segmentation allows the security-critical envelope component to be discarded while the board structure is reused, resolving the contradiction between maintaining security features and reducing waste.
Solution Approach 2:
The patent implements a system where the envelopes containing playing cards are discarded after use, while the backing member with pocket structures is recovered and reused for subsequent games. This selective discarding and recovery approach maintains security (by discarding used envelopes) while reducing overall waste (by reusing the board).
2Reliability
If a single-use drawing game board is used, then security features are maintained, but cost-effectiveness deteriorates
Solution Approach 1:
By segmenting the game board into a reusable backing member and disposable envelope sets, the system allows expensive security features in the board structure to be reused across multiple games, while only inexpensive envelope sets are replaced. This improves cost-effectiveness while maintaining security features.
Solution Approach 2:
The system recovers and reuses the backing member across multiple games, amortizing its cost over many uses, while discarding only the envelope sets. This dramatically improves cost-effectiveness compared to discarding entire single-use boards, while the security features embedded in the backing member remain intact.
3Loss of substance
If a reusable drawing game board is created, then waste is reduced, but maintaining security features becomes difficult
Solution Approach 1:
The segmentation of security-critical envelope components from the board structure allows the board to be reused while security is maintained through replacement of envelopes. Each new envelope set can be sealed with fresh security features, making the reusable board as secure as single-use boards.
Solution Approach 2:
New sealed envelopes are prepared in advance with security features before being inserted into the reusable board. This preliminary preparation ensures that security features are intact and未被 compromised before the game begins, maintaining reliability while using a reusable board.
