Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Image reading apparatuses face issues with uneven image concentration due to variations in imaging devices and light sources, and cutting apparatuses have high costs due to contamination and wear of holding members, requiring frequent replacement.

Innovation Solution

A reading-use holding member with a planar base, indicator, holding portion, and reference portion for shading correction, and a cutting-use holding member with a second adhesive layer for removably holding workpieces, allowing for accurate image reading and reducing consumable costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a reference member is provided on the holding member for shading correction, then image reading quality is improved, but the holding member becomes a consumable that requires frequent replacement due to contamination and wear

Engineering Contradiction:

Improveimage reading qualityVSAvoidholding member service life

Core Design Contradiction:

Measurement precisionVSDuration of action of stationary object

Solution Approach 1:

The system is divided into two distinct holding members: a reading-use holding member with a reference portion for shading correction, and a cutting-use holding member without such features. This segmentation allows the reading-use member to maintain high measurement precision while the cutting-use member handles the harsh cutting environment, effectively resolving the contradiction between image quality and service life.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The reading-use holding member acts as an intermediary that provides the reference portion for shading correction without being directly involved in the cutting process. This intermediary component protects the reference portion from contamination and wear by keeping it separate from the cutting operations, thus maintaining both image reading quality and extending the effective service life of the reference member.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Measurement precision

If a reference member is provided on the holding member, then shading correction is enabled, but the cost of the system increases due to frequent replacement of the holding member

Engineering Contradiction:

Improveshading correction accuracyVSAvoidsystem cost

Core Design Contradiction:

Measurement precisionVSEase of manufacture

Solution Approach 1:

By segmenting the holding members into reading-use and cutting-use types, the expensive reading-use member with shading correction features is separated from the consumable cutting-use member. This allows the system to maintain high shading correction accuracy while reducing overall costs by using a simpler, cheaper cutting-use member for the cutting operations.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The cutting-use holding member is designed as a disposable, low-cost component that does not include the expensive reference portion for shading correction. This allows frequent replacement of the cutting-use member without significant cost impact, while the expensive reading-use member with shading correction capabilities is preserved and reused multiple times.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

3Adaptability or versatility

If the holding member is used for cutting operations, then cutting functionality is achieved, but the holding member accumulates scratches and debris requiring replacement after approximately ten uses

Engineering Contradiction:

Improvecutting functionalityVSAvoidholding member durability

Core Design Contradiction:

Adaptability or versatilityVSDuration of action of stationary object

Solution Approach 1:

The system segments the holding member functions into cutting-use and reading-use components. The cutting-use holding member is specifically designed for cutting operations and is replaced after approximately ten uses as a consumable item, while the reading-use holding member with the reference portion is protected from such wear and can be used repeatedly for shading correction.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The reading-use holding member serves as a protected copy or duplicate of the holding member functionality, specifically designed for the non-wear-intensive task of shading correction. This allows the system to have multiple holding members with similar functions but different durability requirements, enabling the cutting-use member to be replaced frequently while the reading-use member maintains its precision features.

Inventive Principle:

Principle #26Copying
