Touch Slider Switching for Fine and Coarse Value Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slide bar controls on electronic devices face difficulty in fine adjustment of set values due to large variation amounts per unit moving distance, making precise adjustments challenging and compromising 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 reduced due to display screen size restrictions, then the device size is reduced, but the variation amount of the slider per unit moving distance becomes larger, making fine adjustment difficult
Solution Approach 1:
The patent implements dynamic switching between multiple slide bars with different variation amounts. The control unit switches between a first slide bar (coarse adjustment, larger variation amount) and a second slide bar (fine adjustment, smaller variation amount) based on operation state. This allows the system to adapt the bar length and variation amount dynamically, resolving the contradiction between display size and adjustment precision.
Solution Approach 2:
The patent divides the adjustment function into multiple segments by providing multiple slide bars. The first slide bar handles coarse adjustment over a large range, while the second slide bar handles fine adjustment over a smaller range. This segmentation allows the system to achieve both coarse and fine adjustment capabilities without requiring a single extremely long bar, thus accommodating display size restrictions.
2Adaptability or versatility
If the range of numerical value to be set is widened, then the functionality is enhanced, but the variation amount of the slider per unit moving distance becomes larger, making precise adjustment difficult
Solution Approach 1:
The system dynamically switches between slide bars based on the required adjustment precision. When coarse adjustment is needed for a wide range, the first slide bar is used. When fine adjustment is needed for precise value setting, the second slide bar is activated. This dynamic adaptation allows the system to maintain both wide range coverage and precise adjustment capability.
Solution Approach 2:
The adjustment range is segmented into coarse adjustment phase and fine adjustment phase. The first slide bar handles the coarse adjustment for the full range, while the second slide bar handles the fine adjustment for precise value setting. This segmentation enables the system to achieve both wide functionality and measurement precision.
3Device complexity
If a single slide bar with large variation amount is used, then the device complexity is reduced, but the ease of operation for fine adjustment deteriorates
Solution Approach 1:
The patent uses dynamic switching to present multiple slide bar options based on operation needs. The control unit detects when the user needs fine adjustment and switches from the first slide bar to the second slide bar. This dynamic approach provides fine adjustment capability without requiring a permanently complex multi-bar structure, thus balancing simplicity and functionality.
Solution Approach 2:
The control unit provides multi-functionality by enabling switching between different slide bar types. The same control system can handle both coarse adjustment (first slide bar) and fine adjustment (second slide bar), making the system universal for different adjustment needs without requiring separate dedicated devices for each function.
4Ease of operation
If a second slide bar with smaller variation amount is introduced for fine adjustment, then the ease of operation for fine adjustment is improved, but the device complexity increases
Solution Approach 1:
The patent implements dynamic switching between slide bars based on operational context. The control unit monitors the adjustment state and switches between the first and second slide bars as needed. This dynamic mechanism allows the system to provide fine adjustment capability only when required, rather than always displaying multiple slide bars, thus minimizing the perceived complexity while maintaining functionality.
Solution Approach 2:
The system prepares multiple slide bars in advance but activates them selectively based on the adjustment phase. The control unit is pre-configured to switch between slide bars when fine adjustment is detected, so the complexity is managed through conditional activation rather than constant display of multiple structures.
