Dynamic Pressure Threshold Control for Input Error Inhibition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices face challenges in inhibiting erroneous operations, such as accidental emergency calls and data deletions, which can have significant consequences and require more stringent prevention than usual input errors.
Innovation Solution
The electronic device incorporates a contact detection unit, pressure detection unit, and control unit that set and adjust pressure thresholds for input reception based on previously input data, utilizing a display unit to confirm functions and a vibration unit to alert the user, thereby ensuring that only intended inputs are processed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed pressure threshold is used for input detection, then the device is simple to operate, but erroneous inputs such as accidental emergency calls and data deletions cannot be effectively inhibited
Solution Approach 1:
The pressure threshold is changed from a fixed value to a dynamic value that changes based on the input history. The control unit adjusts the threshold according to the type of data being input and whether confirmation is required, making the detection mechanism adaptive rather than static.
Solution Approach 2:
The pressure threshold parameter is modified based on the input context. When confirmation is required (e.g., for emergency calls or data deletion), the threshold is set to a higher value, requiring stronger pressure to confirm the input, thereby preventing accidental operations.
2Reliability
If a higher pressure threshold is set for all inputs to prevent erroneous operations, then reliability improves, but ease of operation deteriorates due to increased difficulty in making valid inputs
Solution Approach 1:
Different pressure thresholds are applied to different input scenarios. Normal inputs use a lower threshold for ease of operation, while specific critical inputs (emergency calls, data deletion) require higher thresholds for confirmation, creating localized quality control where needed rather than uniformly across all inputs.
Solution Approach 2:
The higher pressure threshold is applied only partially - specifically when confirmation is required for critical operations - rather than excessively for all inputs. This selective application maintains ease of operation for routine tasks while providing enhanced protection for sensitive functions.
3Reliability
If continuous monitoring of input patterns is implemented to detect erroneous operations, then reliability of input detection improves, but loss of time increases due to additional processing required
Solution Approach 1:
The control unit prepares confirmation requirements in advance by determining whether an input requires confirmation before the actual input is fully processed. This preliminary assessment allows the system to set the appropriate threshold proactively, avoiding time-consuming post-input validation for routine operations.
Solution Approach 2:
The system uses its own input history and context information to automatically determine when confirmation is needed, without requiring external intervention or complex continuous monitoring. The control unit serves itself by making intelligent decisions based on the type of data being input.

AI summary
Erroneous input operations are more surely inhibited than usual erroneous input operations, by an electronic device 1 including a contact detection unit 40, a pressure detection unit 60 and a control unit 10, in a manner that the contact detection unit 40 detects a contact, the pressure detection unit 60 detects a pressure on the contact detection unit 40, the control unit 10 receives an input, and the control unit 10, based on data having already been input, sets a threshold of the pressure for receiving the input.
