Disposable Card Disposal Box with Viewing Windows
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional card disposal systems are laborious and inefficient, requiring large-scale apparatuses to manage and discard used playing cards, which hinders efficient game operation in casinos.
Innovation Solution
A disposal box for used playing cards with a cuboid shape, featuring slits for insertion, viewing windows for confirmation, and a viewing hole for verification, allowing for easy and secure discarding of used cards in a package unit without illegal removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large-scale card disposal apparatus is used to manage and discard used playing cards, then the cards can be securely managed, but the maintenance becomes laborious and the operation efficiency decreases
Solution Approach 1:
The patent divides the card disposal system into two parts: a reusable secure disposal box that maintains security requirements, and a disposable outer packaging that handles the laborious aspects. The disposable packaging is segmented into multiple layers including a barrier layer and a structural layer, allowing the security-critical components to be reused while the non-critical packaging is discarded after single use.
Solution Approach 2:
The patent employs disposable outer packaging made of paper or plastic materials that is used once and then discarded. This disposable packaging encloses the reusable disposal box containing the used cards, transferring the maintenance burden to a cheap, single-use component while preserving the security function in the reusable disposal box.
2Measurement precision
If a large-scale card disposal apparatus is used to count and manage each card individually, then accurate card management is achieved, but the process takes excessive time and hinders efficient game operation
Solution Approach 1:
The patent applies preliminary action by pre-packaging cards in decks of known quantities (e.g., 52 cards per deck) before they reach the disposal stage. The disposal box is designed to accommodate standard deck configurations, allowing dealers to quickly deposit used cards without individual counting. The viewing windows provide visual confirmation of card presence without requiring precise enumeration.
Solution Approach 2:
The disposal box structure itself provides verification functionality through viewing windows and viewing holes that allow self-checking of card presence and quantity ranges. This eliminates the need for external apparatus to count and verify each card, enabling rapid disposal while maintaining sufficient oversight.
3Reliability
If used playing cards are temporarily stored in a plastic case, then the cards can be protected from loss or theft, but the cards can still be illegally taken out
Solution Approach 1:
The patent uses a disposable outer packaging made of flexible paper or plastic materials that completely encloses the disposal box. This flexible shell provides an additional barrier that prevents illegal removal of cards, as the packaging can be sealed and disposed of with the cards inside, eliminating the risk of cards being extracted from the storage container.
Solution Approach 2:
The patent implements a nested structure where the disposal box containing used cards is placed inside a larger disposable outer packaging. This nested arrangement provides multiple layers of containment: the inner disposal box secures the cards, while the outer packaging provides an additional enclosure that prevents unauthorized access and simplifies disposal by treating the entire assembly as a single unit.

AI summary
A disposal box for used playing cards has a cuboid shape provided with six surfaces, namely, front and back surfaces, left and right surfaces, and upper and lower surfaces in an assembled state. The disposal box includes a slit that is provided in at least one of the six surfaces and enables the used playing cards to be inserted into the disposal box. The disposal box further includes viewing windows that are provided with a plurality of holes having a size at which the playing card cannot be taken out, and can allow the used playing cards contained in the disposal box to be visually recognized. The disposal box is formed of a paper or plastic material, and can be discarded in a state in which the used playing cards are contained in the disposal box.
