Portable Terminal Graphical Registration Display for Settlement Review
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable terminals have limited display space, making it difficult for users to easily recognize the content of registration and settlement processing due to excessive information display, which is not addressed by existing technologies.
Innovation Solution
A portable terminal system that includes an input acceptance unit, list generation unit, graph generation unit, and display control unit to generate and display a graphical representation of the registration content, such as a pie chart, on the terminal's display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If information such as a list, total price, or product details is displayed on a portable terminal display, then the user can recognize the content of registration, but the display space is limited and information becomes excessive relative to the small display size, causing illegibility
Solution Approach 1:
The patent divides the information display into multiple segments: a graph section showing visual representation of product categories and prices, and a list section showing detailed product information. This segmentation allows the limited display space to present both summary and detailed information simultaneously without overcrowding, resolving the contradiction between information completeness and display area limitations.
Solution Approach 2:
The patent introduces a graphical dimension (visual chart) alongside the traditional textual list dimension. By adding this another dimension of information presentation, the system enables users to quickly grasp overall registration content through visual cues while maintaining access to detailed textual information, effectively utilizing the limited display space more efficiently.
2Loss of information
If detailed product information is displayed on the portable terminal, then the user can recognize the content of registration, but the amount of information becomes excessive relative to the display size, causing illegibility and inconvenience
Solution Approach 1:
The display is segmented into a graph portion and a list portion, where the graph provides a simplified visual overview and the list provides necessary detailed information. This segmentation improves readability by preventing information overload while maintaining complete registration content recognition.
Solution Approach 2:
Different portions of the display are assigned different information densities and presentation styles: the graph area uses visual representation for quick understanding, while the list area uses detailed text for comprehensive information. This local quality differentiation optimizes both information recognition and readability within the constrained display space.
