Solution Overview

Problem

The related art button badge manufacturing process suffers from decreased positioning accuracy of a transparent film, leading to difficulties in producing high-accuracy button products.

Innovation Solution

A pressing unit with a first and second pressing portion is used to press the connected portion of a printing medium against a lower die, ensuring precise positioning and cutting of the connected portion on a front member, thereby enhancing the manufacturing accuracy of button products.

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 automatic positioning and pressing of the transparent film without requiring manual user placement. The pressing unit with multiple pressing portions automatically positions the film on the lower die and presses it against the front member, eliminating the need for user intervention while maintaining high positioning accuracy.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The manual mechanical placement operation is replaced with an automated pressing mechanism. The pressing unit uses controlled mechanical forces through multiple pressing portions to position and secure the transparent film, replacing the manual placement action with a more precise automated system.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Device complexity

If manual film placement is used, then the manufacturing process remains simple, but it is difficult to manufacture button products with high accuracy

Engineering Contradiction:
Improvesimplicity of manufacturing processVSAvoidaccuracy of button product
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The pressing operation is divided into multiple segments with different pressing portions (first pressing portion, second pressing portion, third pressing portion) that press different areas of the transparent film at different times. This segmentation allows each portion to be optimized for specific positioning requirements, achieving high overall positioning accuracy while maintaining a relatively simple device structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The first pressing portion presses a first position of the transparent film before the second pressing portion presses a second position. This preliminary action sequence ensures that the film is progressively positioned and secured, with each pressing action building upon the previous one to achieve final high-accuracy positioning.

Inventive Principle:
Principle #10Preliminary action

3Device complexity

If a single pressing portion is used, then the device structure is simple, but the positioning accuracy of the connected portion decreases

Engineering Contradiction:
Improvestructure of pressing unitVSAvoidpositioning accuracy of connected portion
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The pressing unit is divided into multiple pressing portions (first, second, and third pressing portions) that independently press different positions of the connected portion at different times. This segmentation enables precise control over the positioning of the connected portion, achieving high manufacturing precision while maintaining a manageable device structure through modular design.

Inventive Principle:
Principle #1Segmentation

AI summary

To provide a pressing unit capable of manufacturing a button product with high accuracy. A pressing unit is configured to press a connected portion of a printing medium against a lower die, the printing medium including: a connected portion having a sheet shape and configured to be connected to a front member and a back member constituting a button product; a remaining portion having a sheet shape and different from the connected portion; and a coupling portion coupling the connected portion and the remaining portion, and the pressing unit includes: a first pressing portion configured to press the connected portion against the lower die; and a second pressing portion configured to press the connected portion against the lower die. The second pressing portion is configured to press, after the first pressing portion presses a first position of the connected portion, a second position different from the first position of the connected portion.
