Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current parking assistance systems face challenges in accurately presenting the surroundings of a vehicle, particularly when maneuvering into or out of a parking space, due to the absence of distance information, which can lead to optical artifacts and require costly additional sensors.
Innovation Solution
A parking assistance system that uses a camera and image evaluation unit to adapt a grid structure based on the orientation of other vehicles, eliminating the need for expensive sensors by projecting images onto an adaptable grid structure, such as a virtual hemisphere, and incorporating a generic vehicle model for improved presentation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a hemisphere grid structure is used to present three-dimensional surroundings, then the visual presentation is improved, but optical artifacts appear when objects are closer than the projection surface
Solution Approach 1:
The patent applies the dynamics principle by making the grid structure adaptive rather than static. The system dynamically adjusts the grid structure based on detected object distances and orientations, transforming it from a fixed hemispherical projection surface to a flexible, context-dependent representation that eliminates optical artifacts while maintaining visual clarity.
Solution Approach 2:
The patent changes the parameters of the grid structure based on detected object characteristics. By modifying the grid's geometry, density, and orientation according to object distance and angle, the system optimizes the projection to prevent optical artifacts while preserving accurate spatial representation.
2Measurement precision
If additional sensors such as sonar or lidar are deployed to establish distance, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent uses image copying and processing techniques to extract distance and orientation information from visual data. By analyzing the projected image against the grid structure, the system derives spatial measurements without requiring physical distance sensors, effectively creating a virtual measurement system from optical copies.
Solution Approach 2:
The patent makes the camera system multi-functional by enabling it to perform both visual presentation and distance measurement tasks. The same imaging components used for display are also utilized for spatial analysis, eliminating the need for dedicated sensing hardware and reducing overall system complexity.
3Device complexity
If a fixed grid structure is used for projection, then device complexity is reduced, but adaptability to different vehicle orientations and positions is limited
Solution Approach 1:
The patent transforms the static grid structure into a dynamic one that adapts to vehicle orientation and position. The grid parameters are continuously adjusted based on detected object characteristics, enabling accurate spatial representation across varying operational contexts without requiring multiple fixed grid configurations.
Solution Approach 2:
The patent adds adaptability dimensions to the grid structure by introducing parameters for orientation, scaling, and transformation. This allows the two-dimensional projection to accommodate three-dimensional spatial variations, enabling accurate representation of surroundings regardless of vehicle position or angle.
