Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mind map editing systems on touch integrated machines require cumbersome keyboard input and lack intelligence in hierarchical logic, making them inefficient and difficult to use.
Innovation Solution
A display system with a processor that receives a trajectory point sequence from a user, generates content, and displays it, recognizing identification sequences to determine feature identifiers and cluster relationships, thereby automatically generating display regions in a preset format.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If keyboard input is used for mind map editing, then input precision can be maintained, but operation complexity and time consumption increase significantly
Solution Approach 1:
The patent replaces the mechanical keyboard input system with a touch-based trajectory input system. Users draw hierarchical structures directly on the touchscreen using finger or stylus trajectories, eliminating the need for external keyboards and reducing operational complexity while maintaining input precision through gesture recognition.
Solution Approach 2:
The system automatically generates mind map nodes and hierarchical relationships based on user-drawn trajectories without requiring manual keyboard input. The trajectory analysis algorithm automatically interprets drawing gestures and converts them into structured mind map data, making the system self-sufficient and reducing user burden.
2Adaptability or versatility
If traditional mind map editing methods are used, then hierarchical structure can be created, but the process is tedious and lacks intelligence
Solution Approach 1:
The patent replaces manual keyboard-based hierarchical editing with intelligent trajectory recognition. The system analyzes drawing trajectories to automatically identify hierarchical relationships, node connections, and structural patterns, significantly improving editing efficiency while maintaining full hierarchical structure capability.
Solution Approach 2:
The system provides real-time feedback during trajectory input by displaying preview of the emerging hierarchical structure. As users draw, the system continuously analyzes the trajectory and updates the mind map structure preview, allowing users to verify and adjust the hierarchical relationships before finalizing, thereby improving both efficiency and accuracy.
3Measurement precision
If external input devices are required, then input precision can be maintained, but device complexity increases
Solution Approach 1:
The patent merges the input device and display device into a single touchscreen integration. The touchscreen serves both as the display interface and the input interface, eliminating the need for separate external input devices like keyboards or mice, thereby reducing system complexity while maintaining input accuracy through direct touch interaction.
Solution Approach 2:
The touchscreen performs multiple functions simultaneously: it displays the mind map interface, receives user input through touch gestures, and provides visual feedback. This multi-functional design eliminates the need for dedicated external input devices, simplifying the overall system architecture while preserving input precision.
