Touch Contact Zones for Precise Multi-Function Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with touch screens face challenges in precise and efficient function selection due to the need for initial activation of touch keys and limited functionality, as well as imprecision in timing-based selection methods.
Innovation Solution
An electronic device with control means comprising multiple contact zones, where each function is linked to a predetermined time threshold, allowing for efficient and rapid selection by detecting contact, measuring time, and comparing it with predefined thresholds to activate functions without requiring specific key combinations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If timing-based function selection is used, then function selection precision is improved, but user operation complexity increases
Solution Approach 1:
The patent divides the contact zone into multiple distinct contact keys, each associated with specific functions. This segmentation allows users to select functions by pressing specific keys rather than relying on precise timing, thereby maintaining function selection precision while reducing operational complexity.
Solution Approach 2:
The patent changes the selection parameter from time duration to spatial position (which contact key is pressed). By measuring which contact zone receives the touch rather than how long the touch lasts, the system achieves accurate function selection without requiring users to master precise timing.
2Adaptability or versatility
If multiple functions are integrated, then device versatility is improved, but control mechanism complexity increases
Solution Approach 1:
The patent implements a universal contact zone structure where multiple contact keys can be pressed simultaneously or individually. Each contact key can trigger different functions based on combination logic, allowing a limited number of physical contacts to control a large number of functions, thereby increasing versatility without proportionally increasing control mechanism complexity.
Solution Approach 2:
The patent adds a combinatorial dimension to the control mechanism by allowing multiple contact keys to be pressed simultaneously. This transforms the control space from one-dimensional (single key selection) to multi-dimensional (key combinations), enabling exponential growth in controllable functions with linear growth in physical contact keys.
3Measurement precision
If precise timing measurement is required, then function selection accuracy is improved, but measurement complexity increases
Solution Approach 1:
The patent replaces the mechanical timing measurement system with an electrical detection system. Instead of measuring the duration of a touch, the system detects which contact keys are pressed and uses combination logic to determine the selected function. This substitution eliminates complex timing measurements while maintaining or improving selection accuracy.
Solution Approach 2:
The patent uses multiple contact keys as physical representations of different functions or function groups. Each contact key serves as a copy or indicator of specific functions, allowing users to select functions by pressing corresponding keys rather than measuring time durations. This copying approach simplifies the measurement process while preserving function selection accuracy.
