Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with touch sensors require multi-tap operations to magnify or reduce images, which can be cumbersome for users.
Innovation Solution
An electronic device equipped with a display unit, pressure detection unit, and control unit that allows image magnification or reduction based on detected pressure, contact number, and shift amount, eliminating the need for multi-tap operations by enabling zoom mode activation through single-level pressing and sweeping motions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multi-tap operations are used to magnify or reduce images, then image zooming functionality is achieved, but ease of operation deteriorates due to the complexity of the input process
Solution Approach 1:
The patent changes the parameter of input detection from multi-tap contact events to pressure magnitude and contact duration. By detecting pressure levels and holding time, the system distinguishes between zoom-in, zoom-out, and other operations without requiring multiple taps, thereby simplifying the user operation while maintaining functional complexity.
Solution Approach 2:
The patent replaces the mechanical multi-tap operation sequence with a pressure-based detection system. Instead of requiring sequential mechanical tap actions, the system uses pressure sensors to detect force magnitude and duration, substituting a complex temporal sequence of simple actions with a single action containing multiple detectable parameters.
2Ease of operation
If pressure detection is added to enable intuitive zooming, then ease of operation improves, but device complexity increases due to additional hardware
Solution Approach 1:
The patent makes the touch panel serve multiple functions: it acts as both the display interface and the pressure sensing interface. By integrating pressure detection capability into the existing touch panel structure, the system achieves zoom functionality without adding separate hardware components, thus improving ease of operation while minimizing device complexity increase.
Solution Approach 2:
The patent merges the display function and input detection function into a single integrated component. The touch panel simultaneously provides visual output and pressure sensing input, combining what would traditionally be separate systems into one unified component, thereby reducing overall device complexity while enabling advanced interaction modes.
