Solution Overview
Problem
Conventional methods for producing stamping-face plates are costly and complex, with waste materials and large-scale mechanisms contributing to high commodity expenses and design limitations, while also facing issues with material deformation and high costs of edge thermal heads.
Innovation Solution
A stamping-face plate holder using a plate holding member with a porous material impregnated with ink, covered by a heat-resistant film, which is integrated into a thermal printer system to efficiently produce stamping-face plates with reduced waste and complexity, employing a normal thermal head for cost-effectiveness and simplicity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a cassette case containing sponge material is used to make stamping-face plates, then stamping-face plates can be produced, but the cassette case becomes waste product when material is used up, raising commodity expenses
Solution Approach 1:
The invention separates the cassette case from the sponge material. The cassette case becomes a reusable holder that can contain multiple replaceable sponge material sheets. This segmentation allows the case to be used repeatedly while only the consumable sponge material is discarded, significantly reducing waste.
2Adaptability or versatility
If a thermal printer with a cassette case is used to make various sizes of stamping-face plates, then versatility is achieved, but the mechanism becomes complex and large in scale
Solution Approach 1:
The invention divides the system into a simple reusable cassette case and replaceable sponge material sheets. The cassette case provides the structural framework while the interchangeable sponge sheets provide the variable stamping surfaces in different sizes and designs, simplifying the overall mechanism.
Solution Approach 2:
The cassette case is designed as a universal holder that can accommodate multiple different sponge material sheets of various sizes and stamping patterns. This multi-functionality allows a single cassette case to serve multiple purposes, reducing the need for multiple specialized devices.
3Productivity
If maximum size material is used to make stamps of various sizes, then material waste increases, but using smaller materials requires more frequent replacement
Solution Approach 1:
The sponge material is divided into multiple separate sheets that can be independently used and replaced. Each sheet can be optimally sized for specific stamping requirements, eliminating the waste of using maximum size material for small stamps while avoiding the inefficiency of frequent replacements.
Solution Approach 2:
The invention enables selective replacement of only the consumed sponge material sheets while retaining and reusing the cassette case holder. This approach recovers the reusable components and discards only the necessary consumable portions, optimizing material utilization.
4Ease of manufacture
If an edge head thermal head is used to make stamping-face plates, then production capability is achieved, but the cost is about three times as expensive as normal thermal heads
Solution Approach 1:
The invention introduces a film as an intermediary layer between the thermal head and the sponge material. This film protects the sponge material from direct contact with the thermal head, allowing the use of less expensive normal thermal heads instead of costly edge heads, while still achieving effective stamping-face plate production.
