Tape Printer Display Block Break Lines and Sequence Numbers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The limited display area of liquid crystal displays in tape printers makes it difficult for users to distinguish and manage multiple blocks of text, leading to potential errors in editing the wrong block.
Innovation Solution
Incorporating block break lines and numbers on the display to indicate block sequences, along with scrolling functionality and cursor management to enhance display efficiency and user interaction, allowing users to easily identify which block is being displayed and preventing editing mistakes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the display area is kept small to maintain a compact printer design, then the printer size is reduced, but the user cannot easily distinguish and manage multiple blocks of text
Solution Approach 1:
The display area is segmented into multiple functional zones: a main display area for showing text content and a side display area for showing block numbers and block break lines. This segmentation allows the system to provide comprehensive information without requiring a large overall display area, thus maintaining compact printer size while improving block identification ease.
2Ease of operation
If block numbers and break lines are displayed to improve block identification, then the user can easily determine which block is being displayed, but the available space for text display is reduced
Solution Approach 1:
The patent utilizes a two-dimensional display layout where block numbers are positioned in one dimension (side display area) and text content is positioned in another dimension (main display area). This dimensional arrangement allows both block identification information and text content to be displayed simultaneously without significantly reducing the text display space, as they occupy different spatial dimensions on the display.
3Reliability
If the display shows more information about blocks, then editing errors are prevented, but the display becomes more complex and harder to read
Solution Approach 1:
Different parts of the display are assigned different functions with distinct visual characteristics. The main display area shows text content with standard formatting, while the side display area shows block numbers and break lines with distinct visual styling. This local differentiation allows the display to provide comprehensive information for editing accuracy while maintaining visual clarity and reducing overall complexity through functional specialization.

AI summary
A plurality of blocks are displayed in an arraying direction on a display (5) of a printer (1). A block break line (862, 863, 864, 85) is displayed between adjacent blocks of the plurality of blocks. The block break line indicates a break position between the adjacent blocks of the plurality of blocks. A front end break line (861) is displayed in front of a front end block. A back end break line (866) is displayed in back of a back end block. Block numbers (89) are displayed above the block break line and the front end break line. The block numbers indicate sequence numbers of the plurality of blocks.
