Dynamic Load Threshold Adjustment for Input Level Distinction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing input devices that accept inputs based on pressing loads struggle to accurately distinguish between intended and unintended input levels, leading to potential malfunctions, such as premature shutter clicks or focus issues in camera applications, due to user-specific pressing force adjustments and lack of flexibility in load threshold settings.
Innovation Solution
An electronic device equipped with a load detecting unit and a control unit that dynamically adjusts load standards for accepting and releasing inputs, widening the interval between first and second-level input standards after a predetermined time of consistent pressing load detection, allowing for precise control of input levels and reducing unintended input acceptance or release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If fixed load standards are set for accepting and releasing inputs, then the device can distinguish between first-level and second-level inputs, but users may unintentionally trigger wrong input levels due to individual pressing force variations
Solution Approach 1:
The patent applies dynamics by making the load standards adjustable rather than fixed. The control unit dynamically changes the first load standard and second load standard based on detected pressing loads, allowing the thresholds to adapt to different users' pressing forces while maintaining accurate input level distinction
Solution Approach 2:
The patent changes the parameters (load standards) based on detected pressing loads. When a pressing load satisfying the first load standard is detected, the control unit changes the first load standard and/or second load standard to widen the interval between them, preventing unintended input level transitions while maintaining measurement precision
2Speed
If the interval between first and second load standards is kept narrow for responsive input detection, then user inputs are recognized quickly, but unintended second-level inputs may be triggered during normal first-level input maintenance
Solution Approach 1:
The patent makes the load standards dynamic rather than static. The control unit continuously monitors pressing loads and adjusts the first and second load standards to maintain an appropriate interval, widening it when needed to prevent unintended second-level inputs while remaining responsive to genuine user intentions
Solution Approach 2:
The patent implements feedback by having the control unit detect pressing loads and use this information to adjust the load standards. When a pressing load satisfying the first load standard is detected for a predetermined time, the system feedback-adjusts the standards to widen the interval, preventing harmful unintended inputs
3Measurement precision
If the load standards are adjusted frequently to adapt to user pressing patterns, then input accuracy improves, but system complexity and processing overhead increase
Solution Approach 1:
The patent applies periodic action by adjusting the load standards at specific intervals or conditions rather than continuously. The control unit changes the standards when a pressing load satisfying the first load standard is detected for a predetermined time period, providing periodic adjustments that improve accuracy without excessive processing overhead

AI summary
An electronic device, which accepts inputs in a plurality of levels according to pressing loads, after a first-level input is accepted, when a load detecting unit continuously detects a pressing load, which satisfies a first load standard for releasing the acceptance of the first-level input and does not satisfy a second load standard for accepting a second-level input higher than the first load standard, for a predetermined time period, the control unit controls at least one load standard of the first load standard and the second load standard so that an interval from the first load standard to the second load standard widens.
