Solution Overview

Problem

Existing hand-held devices for applying adhesive, covering, or colored materials are complex and costly to manufacture, with inefficient movement mechanisms and potential for material looping during application.

Innovation Solution

A hand-held device with a detachable housing design featuring a central application gib and swivel drive connection between supply and take-up reels, ensuring smooth material transfer and preventing looping, while allowing for easy assembly and cost-effective production.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If motion stops are arranged at application member portions to border relative movement, then the application member portions can be controlled to move between application and storage positions, but the device becomes more complex and costly to manufacture

Engineering Contradiction:
Improvecontrolled movement of application member portionsVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The motion stops are extracted from the application member portions and transferred to the housing. This allows the application member portions to maintain controlled movement capability while reducing their own complexity. The housing now carries the control function, simplifying the overall device structure and reducing manufacturing costs.

Inventive Principle:
Principle #2Taking out (Extraction)

2Productivity

If application member portions are made moveable in relation to each other, then material can be transferred between application and storage positions, but the manufacturing cost and complexity increase

Engineering Contradiction:
Improvematerial transfer capabilityVSAvoidmanufacturing cost
Core Design Contradiction:
ProductivityVSEase of manufacture

Solution Approach 1:

The application member is segmented into multiple portions (first and second application member portions) that can move independently. This segmentation enables efficient material transfer between application and storage positions while allowing each portion to be manufactured separately, potentially reducing overall manufacturing complexity and cost.

Inventive Principle:
Principle #1Segmentation

3Ease of manufacture

If a detachable housing design is used, then assembly and manufacturing become easier and more cost-effective, but the structural integrity and reliability may be compromised

Engineering Contradiction:
Improveassembly easeVSAvoidstructural integrity
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The housing is divided into detachable first and second housing parts that can be assembled and manufactured separately. This segmentation enables easier assembly and more cost-effective production while maintaining structural integrity through proper connection design between the housing parts.

Inventive Principle:
Principle #1Segmentation
