Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle systems for automatically opening doors based on user intention are unreliable due to difficulties in perceiving and reaching the control panel, leading to failed activation.
Innovation Solution
An assembly module with an optical sensor system that includes auxiliary means to enhance user intention detection, such as variable activation regions and illumination states, to provide a more reliable operating signal, including the use of display elements and capacitive sensors to assist users in making their intentions known.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a visible control panel is provided for user interaction, then the user can initiate door opening, but the user may fail to perceive or reach the control panel in time
Solution Approach 1:
The patent replaces the mechanical/optical control panel system with a capacitive sensor system that detects electrical field changes from the user's body. This eliminates the need for visual perception and physical reaching, as the sensor can detect the user's approach and intentions through capacitive coupling, thereby resolving the contradiction between ease of operation and reliability.
Solution Approach 2:
The patent introduces an intermediary capacitive field between the user and the control system. Instead of direct visual contact with a control panel, the user's body capacitance serves as an intermediary that triggers the operating signal, allowing reliable detection without requiring the user to see or reach the control interface.
2Adaptability or versatility
If the activation region is monitored with fixed parameters, then the system is simple to implement, but it cannot adapt to different user needs and situations
Solution Approach 1:
The patent implements dynamic monitoring by continuously adjusting the activation region parameters (position, size, sensitivity) based on detected user presence and behavior patterns. The system transitions from static to dynamic operation, adapting the monitoring parameters in real-time to different user situations while maintaining manageable complexity through progressive activation of monitoring features.
Solution Approach 2:
The patent segments the monitoring system into multiple independent detection zones with different sensitivity levels and functions. By dividing the activation region into segments, the system can apply different monitoring strategies to different areas, increasing adaptability to various user intentions while keeping each segment's complexity manageable.
