Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for controlling the electric opening and closing of vehicle doors using capacitive sensors are prone to false triggering, especially in rainy conditions, leading to frequent unintended opening and closing of the vehicle door.
Innovation Solution
A method and device that utilize a capacitive sensing area with multiple sensing points to collect touch sliding operations, determine whether the operation is accidental based on trigger state information, and control the door opening or closing only when the operation is intentional, thereby reducing false triggering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If capacitive sensors are used to detect user touch and click actions for electric opening and closing of vehicle doors, then the ease of operation is improved, but the reliability deteriorates due to false triggering in rainy conditions
Solution Approach 1:
The capacitive sensing area is divided into multiple capacitive sensing points arranged in sequence. Instead of using a single capacitive sensor, the system segments the sensing area into multiple points that detect touch sliding operations sequentially, allowing differentiation between intentional user actions and accidental touches caused by rainfall.
Solution Approach 2:
The system dynamically evaluates touch operations by analyzing the sliding path across multiple sensing points and comparing it against predetermined valid sliding paths. The control unit adapts its decision-making process by considering the sequence and pattern of triggered sensing points, enabling dynamic discrimination between legitimate user intent and environmental interference.
2Reliability
If multiple capacitive sensing points are used to detect touch sliding operations, then the reliability is improved by reducing false triggering, but the device complexity increases
Solution Approach 1:
Multiple capacitive sensing points are merged into a unified capacitive sensing area with integrated control logic. The control unit combines signals from all sensing points and evaluates them collectively against predetermined valid sliding paths, simplifying the overall system architecture while maintaining high reliability through coordinated multi-point detection.
Solution Approach 2:
The capacitive sensing area serves multiple functions: it detects both the presence and sequence of touch operations, determines sliding direction, validates user intent, and distinguishes between intentional actions and environmental interference. This multi-functionality reduces the need for separate detection mechanisms, thereby controlling device complexity while enhancing reliability.
