Vehicle Door Trim with Camera-Linked Display Panel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rear passengers in vehicles lack information about the external side and rear traffic environment when opening the door, increasing the risk of hitting obstacles due to blind spots and adverse weather conditions.
Innovation Solution
A door trim with a luminous display panel and camera system that provides real-time images of the side and rear road traffic, integrated into the door trim, allowing passengers to check for obstacles before opening, featuring a flexible OLED display, protective screen, and touch-sensitive interface for intuitive use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If rear passengers open doors without external visibility, then door opening speed is fast, but safety is compromised due to blind spots and inability to detect obstacles
Solution Approach 1:
The camera system captures images of the external environment before the door opening action occurs. The display panel shows these images to the passenger in advance, allowing them to detect obstacles and assess safety conditions before actually opening the door, thus preventing accidents without adding significant time delay to the overall door opening process
Solution Approach 2:
The camera and display panel act as an intermediary system between the passenger and the external environment. Instead of requiring the passenger to directly see outside through windows or mirrors, the intermediary camera system captures and transmits visual information about obstacles and traffic conditions, enabling safe door opening decisions without direct line-of-sight requirements
2Measurement precision
If conventional mirrors are used for side viewing, then device complexity is low, but measurement precision is insufficient due to blind spots and distortion
Solution Approach 1:
The patent replaces the mechanical mirror system with an electronic camera-based imaging system. Instead of relying on optical reflections from mirrors that create blind spots and distorted views, the camera system directly captures accurate images of the external environment, including areas invisible to conventional mirrors, thereby improving measurement precision while accepting increased device complexity
Solution Approach 2:
The camera system creates a visual copy of the external environment and displays it on the panel. This copy provides a complete and accurate representation of the surrounding area, including blind spots that cannot be seen with conventional mirrors, allowing passengers to assess safety conditions with superior precision
3Ease of operation
If display panel is positioned away from door trim, then manufacturing is simpler, but ease of operation decreases as passengers must turn their heads to check
Solution Approach 1:
The display panel is merged with the door trim assembly, creating an integrated unit. This allows the display to be positioned exactly where the passenger naturally looks when reaching to open the door, eliminating the need to turn the head and making the safety check as convenient as the door opening action itself, while the integration is achieved through standard automotive assembly processes
4Ease of operation
If flexible curved display is used, then ease of operation improves with natural viewing angle, but manufacturing precision requirements increase
Solution Approach 1:
The patent employs a flexible display panel that can be curved to match the contours of the door trim. This curved configuration allows the display surface to be oriented perpendicular to the door opening direction, providing an optimal viewing angle for passengers without requiring them to turn their heads, while the flexibility of the display technology accommodates the curvature requirements
