Front Member Contact Structure to Reduce Lamination Damage

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In existing button product manufacturing devices, the front lids are laminated, leading to potential damage of the front surface due to contact with other front lids.

Innovation Solution

The front member is designed with a contact member protruding from one surface, allowing it to be positioned between laminated front members to prevent direct contact and damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If front members are laminated and accommodated in a stocker, then storage efficiency and productivity are improved, but the front surface of one front member may be damaged by contact with another front member

Engineering Contradiction:

Improvestorage efficiencyVSAvoidfront surface damage

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

A protective film is introduced as an intermediary layer between the front surface of one front member and another front member in the lamination stack. This protective film prevents direct contact between front surfaces, thereby eliminating the harmful effect of surface damage while maintaining the high-density lamination storage configuration.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The protective film is applied in advance to the front surface before lamination storage. This prior protection ensures that when multiple front members are stacked, the vulnerable front surface is already shielded, preventing damage before it can occur during storage or handling.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

2Object-affected harmful factors

If a protective film is added to prevent surface damage, then surface protection is improved, but device complexity and manufacturing steps increase

Engineering Contradiction:

Improvefront surface protectionVSAvoidmanufacturing steps

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The protective film application process is merged with the existing lamination storage process. Rather than adding a separate, independent protection step, the protective film is integrated into the lamination stack configuration, allowing both protection and storage to be achieved through a unified approach that minimizes additional complexity.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

The present invention prevents the surface of a front member from being damaged by another front member even when the front members are stacked. The front member is included in a button member that constitutes a button product in conjunction with a printing object medium, and comprises: a plate-like front member body which has one surface and the other surface; and a contact member which is provided so as to protrude from the one surface of the front member body.
