Solution Overview

Problem

Existing carrier bags used for transporting cash are susceptible to damage, non-reusable, and costly, with a lack of robustness and security features to prevent unauthorized access and ink coating.

Innovation Solution

A carrier bag with an outer mesh and a waterproof inner liner, featuring a seal and holes for penetration by hollow nails from a carrier box, which can include an ink reservoir, and additional security features like a lock and sensors to prevent unauthorized access.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If sealable bags are used to carry cash, then security against unauthorized access is provided through ink coating, but the bags are susceptible to damage and are not reusable

Engineering Contradiction:

Improvesecurity against unauthorized accessVSAvoidresistance to damage

Core Design Contradiction:

ReliabilityVSStrength

Solution Approach 1:

The carrier bag is divided into two distinct layers: an outer mesh layer providing structural strength and damage resistance, and an inner liner layer providing security through ink coating. This segmentation allows each layer to specialize in its respective function without compromising the other.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The carrier bag uses a composite structure combining mesh material for durability and a liner material for security functionality. This composite approach integrates the advantages of both materials - the mesh provides tensile strength and damage resistance while the liner provides the ink coating security feature.

Inventive Principle:

Principle #40Composite materials

2Reliability

If sealable bags are used to carry cash, then security against unauthorized access is provided through ink coating, but the bags have high cost per unit due to non-reusability

Engineering Contradiction:

Improvesecurity against unauthorized accessVSAvoidcost per unit

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

By separating the security function (inner liner) from the structural function (outer mesh), the design allows the durable outer mesh to be reused while only the inner liner needs replacement if compromised, significantly reducing the cost per use compared to completely disposable bags.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The outer mesh structure is designed to be reusable and recoverable, while the inner liner can be discarded if compromised. This selective recovery approach reduces overall costs by maintaining the expensive structural component across multiple uses.

Inventive Principle:

Principle #34Discarding and recovering

3Ease of operation

If the inner liner is made thin for flexibility, then ease of operation is improved, but vulnerability to damage increases

Engineering Contradiction:

ImproveflexibilityVSAvoidvulnerability to damage

Core Design Contradiction:

Ease of operationVSStrength

Solution Approach 1:

The thin inner liner is protected by the outer mesh layer that absorbs mechanical damage, allowing the liner to remain thin for flexibility while the mesh provides the necessary strength and damage resistance.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The outer mesh layer acts as a protective cushion that prevents damage to the inner liner before the liner can be compromised, allowing the liner to be thin without sacrificing overall durability.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)
