Transparent Escrow Chamber for Table Game Document Handler
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing document handling systems for table games do not allow players to visually confirm the authenticity of documents after evaluation, leading to transparency and security concerns in the handling and storage of documents.
Innovation Solution
A document handler with a deposit chamber, an external escrow chamber visible to players, and a drive device that transports genuine documents from the deposit chamber to the escrow chamber for visual confirmation, allowing players to observe and potentially retrieve documents for verification, before transferring them to a stacker.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If documents are stored in an internal escrow chamber inside the bill acceptor, then security of documents is improved, but players cannot visually confirm document authenticity and transparency deteriorates
Solution Approach 1:
The escrow chamber is nested within the bill acceptor structure, with the transparent portion integrated into the casing. This allows the escrow chamber to be securely housed within the device while maintaining visual transparency through the transparent casing portion, enabling players to observe documents without compromising security.
Solution Approach 2:
The escrow chamber casing is made transparent or translucent, allowing visual observation of documents stored inside. This transparency feature enables players to confirm document authenticity and presence without physical access, resolving the contradiction between security and transparency by making the security mechanism itself visible.
2Loss of information
If documents are made visible to players in the escrow chamber, then transparency of document handling is improved, but security against unauthorized removal deteriorates
Solution Approach 1:
The transparent portion is selectively positioned on the escrow chamber casing at locations where visual observation is needed, while other portions of the casing and the internal escrow structure remain opaque or secure. This localized transparency allows player verification without creating general access points for unauthorized removal.
3Measurement precision
If bills are inserted into the validator for authentication, then document verification is improved, but players cannot observe or confirm bills during the validation process deteriorates
Solution Approach 1:
The system performs preliminary authentication of documents through the validator before transferring them to the escrow chamber. Once authenticated, the documents are moved to the transparent escrow chamber where players can observe them. This sequence ensures verification accuracy is maintained while providing subsequent visual confirmation.
