Solution Overview

Problem

Existing button product manufacturing devices face challenges in achieving high accuracy due to user involvement in placing transparent films, leading to decreased positioning accuracy.

Innovation Solution

A button product manufacturing device with a printing unit, die set, and conveying unit that automates the process by supporting and conveying a printed medium over a front member, improving accuracy without user intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a user manually places a transparent film on a film placement surface, then the user can participate in and enjoy the manufacturing process, but the positioning accuracy of the transparent film decreases

Engineering Contradiction:

Improveuser participation in manufacturingVSAvoidpositioning accuracy of transparent film

Core Design Contradiction:

Ease of operationVSManufacturing precision

Solution Approach 1:

The system performs film placement automatically without user intervention. The conveyer unit transports the printed medium and the die set executes caulking automatically, eliminating the need for manual film placement while maintaining high positioning accuracy through automated control mechanisms.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The manual mechanical placement operation is replaced with an automated conveyance and positioning system. The conveyer unit mechanically transports the printed medium to the precise position, and the die set mechanically performs caulking, substituting human manual operations with automated mechanical systems that ensure higher precision.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Manufacturing precision

If automated conveyance is implemented, then positioning accuracy of the printed medium is improved, but device complexity increases

Engineering Contradiction:

Improveconveying accuracy of printed mediumVSAvoidcomplexity of conveyance system

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The die set serves multiple functions: it positions the front member, receives the printed medium from the conveyer, performs caulking between the front and back members, and separates the completed button product. This multi-functionality reduces the need for additional dedicated components, thereby limiting the increase in device complexity while maintaining high positioning accuracy through automated conveyance.

Inventive Principle:

Principle #6Universality (Multi-functionality)
