Solution Overview

Problem

Existing paper sheet processing devices require multiple processing units for various operations, leading to increased storage space and operational complexity, as each processing unit must be changed manually for different tasks.

Innovation Solution

A processing machine with a processor and receiver system that allows for easy attachment and positioning of interchangeable blades, such as cutting, perforating, creasing, and micro-perforating blades, using identification patterns and a controller to adjust mechanisms for precise blade alignment and operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple processing units are provided for different processing operations, then various processing tasks can be performed, but storage space increases and cost increases

Engineering Contradiction:

Improveprocessing capabilityVSAvoidstorage space

Core Design Contradiction:

Adaptability or versatilityVSVolume of stationary object

Solution Approach 1:

The processing machine uses a single processing unit that can perform multiple processing operations by changing the processing blade. The reception member is designed with multiple reception portions that can accommodate different types of processing blades (cutting, perforating, creasing, etc.), allowing one machine to replace multiple specialized machines, thereby reducing storage space while maintaining versatility

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The processing blade is divided into different types (cutting blade, perforating blade, creasing blade, etc.), each designed for specific processing operations. These segmented blade types can be interchangeably mounted on the same processing unit, enabling the system to perform various processing tasks without requiring multiple complete processing units

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If multiple processing units are provided for different processing operations, then various processing tasks can be performed, but device complexity increases

Engineering Contradiction:

Improveprocessing capabilityVSAvoidnumber of processing units

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The processing unit is designed as a universal device that can perform multiple processing operations through blade changes. The reception member includes multiple reception portions configured to receive different types of processing blades, allowing a single processing unit to replace multiple specialized units, thereby reducing device complexity while maintaining processing versatility

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If processing units are changed manually for different processing tasks, then processing variety can be achieved, but operational time increases and productivity decreases

Engineering Contradiction:

Improveprocessing varietyVSAvoidprocessing unit change time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

Different types of processing blades are pre-prepared and can be quickly exchanged on the processing unit. The reception member is designed with multiple reception portions that facilitate rapid blade changes, reducing the time required to switch between different processing operations and minimizing operational downtime

Inventive Principle:

Principle #10Preliminary action

4Adaptability or versatility

If multiple processing units are provided, then different processing operations can be performed, but ease of operation decreases due to extensive manual work

Engineering Contradiction:

Improveprocessing operation varietyVSAvoidprocessing unit change operation

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The processing unit is designed as a universal device with a reception member that can accommodate multiple types of processing blades. This unified design simplifies the operation of changing processing types, as users only need to exchange blades rather than entire processing units, thereby improving ease of operation while maintaining processing variety

Inventive Principle:

Principle #6Universality (Multi-functionality)
