Electronic Device Pressure Threshold Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with contact detection units, such as touch sensors, require multiple key presses to correct erroneous operations based on pressure loads, leading to decreased operability.
Innovation Solution
An electronic device with a control unit that sets execution and cancellation standards for press-based operations, where the cancellation standard is higher than the execution standard, allowing for single-touch cancellation of operations by detecting press data against these standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a predetermined operation is executed based on pressure load detection, then operational functionality is improved, but operability deteriorates when erroneous operations occur requiring multiple key presses to correct
Solution Approach 1:
The patent inverts the conventional approach by setting the cancellation standard higher than the execution standard. Normally, cancellation requires more effort than execution, but this patent makes cancellation easier by allowing it when pressure exceeds the higher threshold, while execution requires pressure between the two thresholds. This inversion resolves the contradiction by enabling single-touch cancellation of erroneous operations.
Solution Approach 2:
The patent changes the pressure parameter thresholds to create two distinct standards: an execution standard and a higher cancellation standard. By adjusting these parameter thresholds, the system enables differentiated operation modes where light pressure executes operations and heavy pressure cancels them, thereby improving operability without requiring multiple key presses for correction.
2Adaptability or versatility
If a single execution standard is used for predetermined operations, then device complexity is reduced, but adaptability deteriorates when multiple operation modes are needed
Solution Approach 1:
The patent introduces dynamic threshold adjustment based on operation context. The control unit dynamically switches between execution and cancellation standards depending on the current state, allowing the same hardware to support multiple operation modes without adding physical complexity. This dynamic adaptation enables versatile operation while maintaining simple device architecture.
