Single Thermal Printer Integrating Journal and Receipt Functions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing self-service terminals, such as ATMs, require separate journal and receipt printers, which occupy valuable space, are labor-intensive to maintain, and use duplicate parts, complicating manufacturing and increasing costs due to conflicting requirements for continuous journal printing and customer receipt cutting.
Innovation Solution
A single thermal printer with a single thermal print head that incorporates both receipt and journal printing capabilities, using media feed mechanisms and a selection mechanism controlled by a processor to selectively position the print head and cut media, allowing for simultaneous printing and cutting of receipts while maintaining uninterrupted journal records.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If separate journal and receipt printers are used, then each printer can be optimized for its specific function (continuous printing for journal, cutting capability for receipt), but the total volume occupied increases and maintenance becomes labor-intensive
Solution Approach 1:
The patent combines separate journal and receipt printing functions into a single integrated printer unit. The printer includes a print head that can selectively print on both continuous journal media and receipt media, along with a cutting mechanism that can cut receipt media. This merging reduces the total volume occupied by printers while maintaining the specialized optimization for each function through software-controlled print head selection and cutting mechanism activation.
2Adaptability or versatility
If separate journal and receipt printers are used, then each printer can operate independently, but multiple access points are required for replenishment and servicing
Solution Approach 1:
The patent integrates journal and receipt printing functions into a single printer with a unified media feed system. The printer includes a single access point for loading both continuous journal media and receipt media, and a single cutting mechanism that serves both functions. This integration maintains independent operation through software-controlled print head selection while simplifying maintenance to a single access point.
3Reliability
If separate journal and receipt printers are used, then each printer can use dedicated parts, but duplicate common parts increase manufacturing complexity and cost
Solution Approach 1:
The patent employs a universal print head that can print on both continuous journal media and receipt media, along with a universal cutting mechanism that can cut receipt media. This multi-functionality is achieved through software-controlled selection of the print head and activation of the cutting mechanism, eliminating the need for duplicate common parts while maintaining reliability through dedicated functionality for each media type.
4Volume of moving object
If a single printer is used for both journal and receipt printing, then volume and complexity are reduced, but the conflicting requirements for continuous printing and cutting must be resolved
Solution Approach 1:
The patent uses a dynamic print head selection mechanism that can switch between printing on continuous journal media and receipt media. The printer includes a cutting mechanism that can be activated when receipt media is detected, allowing the system to dynamically adapt to the specific printing task. This dynamic switching resolves the conflicting requirements for continuous printing and cutting by enabling the single printer to perform both functions as needed.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution reduces the volume occupied by printers, simplifies maintenance, and decreases manufacturing complexity and costs by integrating both functions into a single unit, ensuring efficient operation and reduced labor for servicing.
Implementation Method 1
The print head may be arranged to selectively face a feed path of either the first or second media feed mechanism when in a respective one of two rotational positions
