Solution Overview

Problem

Existing paper sheet handling apparatuses require significant time and effort to remove dust and debris, as they often necessitate opening the upper unit to collect dust spread over a wide area on partitioning members.

Innovation Solution

A paper sheet handling apparatus with a dust tray that can be pulled out from the front surface for easy disposal, combined with a slanted dust receiving plate that collects dust into the tray, allowing for efficient removal without opening the upper unit, and positioned below key components like sensors to enhance dust collection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If dust is collected on partitioning members inside the upper unit, then dust can be removed from the transport path, but it requires opening the upper unit and gathering dust spread over a wide area

Engineering Contradiction:
Improvedust accumulation on sensorsVSAvoiddust removal effort
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The dust tray is extracted from the internal structure and made accessible from the front surface of the apparatus. This allows dust to be removed without opening the upper unit, directly resolving the contradiction by separating the dust collection function from the main housing structure.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The dust receiving plate acts as an intermediary component that collects dust from the transport path and directs it to the dust tray. This mediator simplifies the dust removal process by concentrating scattered dust into a single accessible location.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If a dust tray is added to the apparatus, then dust collection becomes easier, but the device complexity increases

Engineering Contradiction:
Improvedust tray accessibilityVSAvoidnumber of components
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The dust tray serves multiple functions: it collects dust from the transport path, provides a removable storage container, and can be accessed independently from the front surface. This multi-functionality justifies the added component by consolidating several dust management tasks into a single element.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The dust management system is segmented into distinct components: the dust tray for collection, the dust receiving plate for guidance, and the removable tray structure. This segmentation allows each component to be optimized independently and simplifies maintenance by enabling easy removal of the dust tray without disassembling the entire apparatus.

Inventive Principle:
Principle #1Segmentation

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Facilitates easy and thorough removal of dust and debris, reducing the effort required and allowing for more comprehensive cleaning without disassembling the apparatus, thereby maintaining sensor accuracy and transport efficiency.

Implementation Method 1

the dust receiving plate slants with the upper unit when the upper unit is opened, and the dust receiving plate is arranged at a position where the dust slid down from the dust receiving plate is collected in the dust tray
