Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display systems for setting values on devices, such as smartphones and personal computers, lack efficiency in allowing operators to quickly select desired numerical values, as they often require manual adjustment of both the amount of numerical value change and switching speed, which can be cumbersome and not easily customizable.

A display apparatus with a display control section, operating point detecting section, movement information detecting sections, and switching speed calculating section, allowing for dynamic adjustment of numerical value change and switching speed based on operator input, enabling seamless selection of desired values by detecting movement patterns and calculating optimal display switches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the amount of numerical value change is increased to reach desired values quickly, then the productivity is improved, but the measurement precision of operator intent deteriorates
Solution Approach 1:
The patent applies dynamics by making the amount of numerical value change variable rather than fixed. The system dynamically adjusts the change amount based on the operator's input speed - using larger increments when the operator inputs quickly and smaller increments when the operator inputs slowly. This resolves the contradiction by adapting the productivity parameter (change amount) to match the precision requirement (operator intent accuracy) in real-time.
Solution Approach 2:
The patent changes the parameter of numerical value increment size based on detected operator input characteristics. By monitoring how quickly the operator enters characters and adjusting the display switch increment accordingly, the system optimizes both the speed of reaching desired values and the accuracy of capturing operator intent, directly addressing the technical contradiction between productivity and measurement precision.
2Productivity
If the switching speed is increased to improve operational efficiency, then the productivity is improved, but the ease of operation deteriorates
Solution Approach 1:
The system dynamically adjusts switching speed based on operator characteristics. By detecting the speed at which operators input characters, the system adapts the numerical value switching speed to match individual operator preferences and capabilities. This ensures high productivity for fast operators while maintaining ease of operation for slower operators, resolving the contradiction between these two parameters.
Solution Approach 2:
The system performs self-adjustment by automatically detecting operator input patterns and configuring optimal display switching parameters without requiring manual setup. The system serves itself by learning from operator behavior and automatically optimizing both productivity and ease of operation, eliminating the need for operators to manually balance these conflicting parameters.
3Adaptability or versatility
If manual adjustment of both amount of numerical value change and switching speed is required, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The system automatically detects operator characteristics and configures optimal display parameters without requiring manual adjustment. By having the system self-configure based on observed operator behavior, full adaptability is achieved while keeping the interface simple and easy to use, resolving the contradiction between adaptability and device complexity.
Solution Approach 2:
The system implements feedback by monitoring operator input patterns and using this information to automatically adjust display parameters. The feedback loop captures operator behavior and translates it into optimized switching speeds and increment sizes, providing adaptability through automatic adjustment rather than manual configuration, thus reducing device complexity.
