Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Bills often remain in cash boxes after extraction, leading to inefficiencies and potential issues in handling.

Innovation Solution

A bill handling system equipped with a camera, grasping unit, and control unit that photographs the cash box interior after bill extraction, determines if a bill remains, and performs error processing if necessary.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a bill extraction mechanism is used to automatically remove bills from a cash box, then productivity is improved, but reliability deteriorates because bills may remain in the cash box after extraction

Engineering Contradiction:

Improvebill extraction efficiencyVSAvoidcomplete bill removal

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The system uses a camera to photograph the cash box interior after bill extraction and provides feedback to the control unit. The control unit analyzes the photographed image to determine whether any bills remain in the cash box, enabling closed-loop verification of the extraction process

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent replaces manual visual inspection with an automated optical detection system. A camera captures images of the cash box interior, and image processing algorithms automatically analyze whether bills remain, substituting mechanical/visual verification with optical-electronic detection

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If manual inspection is used to verify bill extraction, then reliability is improved, but productivity deteriorates due to time consumption

Engineering Contradiction:

Improvedetection accuracyVSAvoidprocessing speed

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The system performs self-verification of bill extraction through automated image capture and analysis. The camera and control unit automatically check whether bills remain in the cash box without requiring external manual inspection, enabling the system to verify its own operation

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

Manual visual inspection is replaced with automated optical detection and image processing. The camera captures images and the control unit analyzes them to determine bill presence, replacing human visual verification with electronic image analysis

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
