Solution Overview

Problem

The existing bill processing apparatuses require a large number of parts to detect when the bill housing part is full, leading to increased manufacturing costs.

Innovation Solution

A paper sheet processing apparatus that uses a magnetic sensor to detect the magnetism of a magnetized body on a moving placing plate, determining if the detected magnetism exceeds a threshold value to indicate a full state, thereby reducing the number of mechanical components needed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a swinging lever and slide lever mechanism is used to detect the full state of the bill housing part, then the detection function is achieved, but the number of parts increases and manufacturing cost inflates

Engineering Contradiction:

Improvedetection functionVSAvoidnumber of parts

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical swinging lever and slide lever detection system with a magnetic detection system. A magnetic body is attached to the pressing plate, and a magnetic sensor detects its position to determine the full state of the bill housing part. This substitution eliminates the need for multiple mechanical components while maintaining reliable detection functionality.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent extracts the detection function from the complex mechanical lever system and isolates it into a separate magnetic detection mechanism. The magnetic body and magnetic sensor work independently to detect the full state, removing the need for the swinging lever, slide lever, and associated mechanical linkages.

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

A paper sheet processing apparatus that can detect in an inexpensive way that a bill housing part is full with bills. The paper sheet processing apparatus includes: a bill housing part that houses a bill in a stacked manner; a placing plate arranged in the bill housing part and moves as a bill is stacked and housed; a magnetic body magnetized and disposed on the placing plate; a magnetic sensor that detects an amount of magnetism from the magnetic body; and a control part that determines whether the amount of magnetism detected by the magnetic sensor is greater than or equal to a threshold value.
