Touch-Adaptive Slide Bar Control for Fine Set-Value Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slide bar systems face difficulty in fine adjustment of set values due to large variation amounts per unit moving distance, making it challenging to operate the slider for precise adjustments without spoiling the convenience of a single-touch operation.
Innovation Solution
A slide bar display control device that includes a first slider and bar, allowing for a second slider and bar to be displayed with a different variation amount per unit moving distance upon a specific operation, enabling fine adjustment without releasing the finger, and switching between different variation amounts based on user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the length of the bar is shortened due to display screen size restriction, then the device size is reduced, but the variation amount of slider per unit moving distance becomes larger making fine adjustment difficult
Solution Approach 1:
The patent applies dynamics by making the bar length adjustable rather than fixed. The control unit dynamically changes the bar length between a first length and a second length based on user operations. When the slider is in a touched state, a different bar length is displayed compared to when it is not touched, allowing the system to adapt its characteristics in real-time based on operational context.
Solution Approach 2:
The patent changes the parameter of bar length to resolve the contradiction. By switching between a first bar length (when slider is not touched) and a second bar length (when slider is touched), the system adjusts the variation amount per unit distance. The shorter second length provides finer control when the user is actively adjusting, while the longer first length provides better overview when not adjusting.
2Adaptability or versatility
If the range of numerical value that can be set is widened, then the versatility of the device is improved, but the variation amount of slider per unit moving distance becomes larger making precise control difficult
Solution Approach 1:
The system dynamically adjusts the bar length based on the operational state. When the slider is touched (active adjustment mode), a shorter second bar length is displayed to provide finer control for precise adjustments. When not touched (overview mode), a longer first bar length is displayed to show the full range of adjustable values, thus adapting to different user needs.
Solution Approach 2:
The patent changes the bar length parameter in response to touch state changes. This allows the system to maintain a wide numerical value range for versatility while providing fine control capability when needed. The control unit switches between first and second bar lengths, effectively changing the scale of adjustment to match the user's current task requirements.
3Ease of operation
If a second bar with smaller variation amount per unit moving distance is displayed, then fine adjustment becomes easier, but two times of touch operation are needed spoiling the convenience of slide bar
Solution Approach 1:
The patent makes the bar length dynamic based on touch state. When the user touches the slider, the system automatically switches to displaying the shorter second bar length optimized for fine adjustment. This eliminates the need for manual switching between different bar views, as the system adapts automatically to the user's intent based on the touch state, maintaining operational simplicity.
Solution Approach 2:
The system performs self-service by automatically detecting the touch state and switching between first and second bar lengths without requiring user intervention. The control unit monitors whether the slider is in a touched state and autonomously adjusts the displayed bar length, thereby providing fine adjustment capability while maintaining the simplicity of single continuous touch operation.

AI summary
The slide bar display control device according to the present invention includes, a display means which indicates a first slide bar including a first slider and a first bar, an input means which can select an arbitrary part of the first slide bar shown on the display means based on touch operation, and a control means which controls the display means and the input means, wherein, when the control means detects that a first operation has been performed in a state that the first slider shown on the display means is being touched in the input means, the display means indicates a second slide bar including a second slider and a second bar, and wherein the second slider is a slider different in a variation amount of a set value per unit moving distance from the first slider.
