Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The integrity and security of documents such as voter ballots and test papers are compromised by the spread of false information and computer-based alteration technologies, necessitating methods to ensure their accuracy and untampered nature.

Innovation Solution

A multifunction print device prints and scans documents with unique identifiers, storing them in a secure container with tamper-evident seals, ensuring no human handling, and maintaining an electronic record of the documents.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If documents are manually handled and stored, then ease of operation is improved, but security and integrity of documents deteriorate due to human error and tampering risks

Engineering Contradiction:

Improveease of document handlingVSAvoiddocument integrity

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent replaces manual mechanical handling of documents with an automated print device system that directly conveys printed documents into the container chamber. This substitution eliminates human contact with documents during the critical printing and storage transition, preventing tampering while maintaining operational efficiency through automated conveyance mechanisms.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces a sealed container chamber as an intermediary between the print device and final document storage. This intermediate sealed environment ensures documents remain protected from external tampering forces while being filled, creating a secure transition zone that maintains both ease of operation and document integrity.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If documents are stored in an open container, then ease of access is improved, but security and protection from tampering deteriorate

Engineering Contradiction:

Improveease of document accessVSAvoiddocument tampering

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent applies preliminary sealing action to the container chamber before documents are fully stored. The seal is prepared and positioned in advance, allowing documents to be conveyed and placed into the chamber through the opening, after which the opening is sealed. This preliminary preparation of the sealing mechanism enables secure closure while maintaining ease of document access during the filling process.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent segments the container into a chamber portion and a sealable opening portion. This segmentation allows the main chamber to remain accessible for document storage while the opening can be independently sealed to prevent tampering. The divided structure enables both ease of document access and protection from harmful factors.

Inventive Principle:

Principle #1Segmentation

3Reliability

If automated printing and conveying is implemented, then document integrity is improved by eliminating human handling, but device complexity increases

Engineering Contradiction:

Improvedocument integrityVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the print device and container into an integrated system where the print device directly conveys documents into the container chamber. This combination eliminates the need for separate manual handling steps and intermediate storage locations, reducing overall system complexity while maintaining automated document integrity protection.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The print device is designed with multi-functionality, serving both as a printing mechanism and as a document conveyance system. This universal design eliminates the need for separate conveyance devices, reducing system complexity while maintaining automated operation that ensures document integrity through elimination of human handling.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

Methods and systems for securing a document within a container include providing a container which has multiple facets that are connected together to form a chamber. One of the facets of the container is a front facet with an opening that is sized with a width that equals or exceeds a width of each of a plurality of document sheets that will be received into the chamber via the opening. The opening is positioned at or below a top edge of the front facet and above a midpoint of the front facet. A print device will print the document sheets, each of which includes a unique identifier (ID). The print device will convey the document sheets into the chamber from the print device, without any human touching the document sheets, to form a stack of the document sheets within the chamber. The opening will be sealed with a sealing material.
