Active Vehicle Outer Panels for Pedestrian Interaction Signaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle interaction devices lack active and automated interaction capabilities with other road users, particularly pedestrians and cyclists, leading to potential dangers due to incorrect speed assessment in built-up areas, especially with electric or hybrid vehicles.
Innovation Solution
An interaction device featuring active exterior trim parts with movable visible components, a vehicle environment sensor system, and an access authorization system, where an evaluation and control unit adjusts these components based on detected threats or authorized users, using adjustable segments and actuating means like electric or pneumatic drives, to enhance visibility and safety through optical and acoustic effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the vehicle remains visually static and silent, then manufacturing costs and system complexity are reduced, but the vehicle's ability to actively communicate with road users and prevent accidents is limited
Solution Approach 1:
The patent applies the dynamics principle by making exterior trim panels movable and adjustable. The trim panels can change their position, angle, and configuration dynamically based on detected scenarios (e.g., pedestrian detection, unauthorized access). This allows the vehicle to actively communicate its state and intentions to road users, transforming a static appearance system into an adaptive interaction system that enhances safety without requiring complete redesign of the vehicle structure.
Solution Approach 2:
The patent implements multi-functionality by using the same movable trim panel system for multiple purposes: visual communication with pedestrians, deterrent signaling for unauthorized access, and aesthetic expression. The trim panels serve both as decorative elements and as active communication devices, reducing the need for separate specialized systems while enhancing interaction capabilities across different scenarios.
2Reliability
If movable components are added to the exterior trim panels, then the vehicle's visibility and communication capability improve, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent applies feedback by using sensors to detect scenarios (pedestrian presence, unauthorized access attempts, vehicle state) and using this information to control the movement and positioning of exterior trim panels. The system continuously monitors the environment and adjusts the trim panel configuration in response, creating a closed-loop safety communication system that enhances reliability by adaptively responding to real-time conditions.
Solution Approach 2:
The patent uses an intermediary control system that translates sensor data into appropriate trim panel movements. This intermediary layer processes information from various sensors and determines the optimal trim panel configuration for each scenario, managing system complexity by providing a structured decision-making layer between detection and actuation.
3Adaptability or versatility
If the vehicle uses active exterior trim parts for communication, then interaction with road users improves, but energy consumption increases
Solution Approach 1:
The patent applies periodic action by using intermittent or on-demand activation of the movable trim panels rather than continuous operation. The system activates the trim panels only when specific scenarios are detected (e.g., pedestrian in proximity, unauthorized access attempt), and can use repetitive movement patterns to convey messages. This approach maintains interaction capability while significantly reducing overall energy consumption compared to continuous operation.
