Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with multiple input modules on the same surface often experience false touches, leading to unnecessary false responses, which degrade input accuracy and user experience.
Innovation Solution
An electronic device comprising a first input module, a second input module, a detection module, and a processing module, where the detection module transmits signals to both regions and receives return signals to analyze user input, allowing the processing module to shield incorrect input information and reduce false touches by determining the source of the input based on signal strength and timing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple input modules are located on the same surface to facilitate various user inputs, then input versatility is improved, but false touches increase leading to input accuracy degradation
Solution Approach 1:
The detection surface is segmented into multiple detection regions, each corresponding to a specific input module. The detection module independently detects touch events in each region and determines the appropriate input module based on the touched region, thereby preventing false touches from propagating to incorrect modules while maintaining multiple input options on the same surface
Solution Approach 2:
A detection module is introduced as an intermediary between the touch surface and the input modules. This detection module detects touch events, determines the touched region, and shields the corresponding input module information, thereby preventing false touches from causing incorrect responses while preserving the versatility of multiple input modules
2Difficulty of detecting and measuring
If signal transmission is performed to detect user input, then input detection capability is improved, but false signal detection increases leading to false responses
Solution Approach 1:
Different detection regions are assigned different detection characteristics and signal analysis methods. The processing module analyzes signals based on their originating region, applying region-specific detection parameters to distinguish valid inputs from false touches while maintaining high detection sensitivity across all input modules
Solution Approach 2:
The detection module continuously monitors signal characteristics from each region and provides feedback to the processing module. Based on this feedback, the system dynamically adjusts detection parameters and shields inappropriate input modules, thereby reducing false responses while maintaining accurate detection of legitimate user inputs

AI summary
An electronic device includes a first input module located at a first region, a second input module located at a second region, a detection module, and a processing module. The detection module is configured to transmit a first signal to the first region and the second region and receive a second signal returned based on the first signal. The processing module is connected to the detection module and configured to analyze the second signal to obtain an analysis result, and shield input information of the first input module or the second input module according to the analysis result.
