Solution Overview

Problem

Existing parking assistant systems for vehicles are costly due to complex device configurations involving external storage units for storing patterns and combining camera images with vehicle traveling traces, increasing manufacturing costs.

Innovation Solution

An automobile camera module that receives real-time steering angle information via CAN communication, generates an estimated traveling trace, and displays it on a display unit, reducing system complexity and memory requirements by using a small-sized memory to store parking modes, directions, and warning messages.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If patterns for displaying traveling direction are stored in external storage units (RAM, ROM) and combined with camera images, then parking assistance functionality is provided, but manufacturing costs increase due to complex device configuration

Engineering Contradiction:
Improvemanufacturing costVSAvoiddevice configuration
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent extracts the pattern storage function from external storage units (RAM, ROM) and eliminates the need for separate pattern libraries. Instead, traveling traces are generated dynamically through mathematical calculations based on steering angle information, removing complex external storage requirements and reducing manufacturing costs

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The system generates traveling traces autonomously using real-time steering angle data from the vehicle's existing sensors and mathematical algorithms. This self-generating approach eliminates dependency on pre-stored patterns in external memory, simplifying the device configuration while maintaining full parking assistance functionality

Inventive Principle:
Principle #25Self-service

2Reliability

If external storage units (RAM, ROM) are used to store traveling direction patterns, then parking assistance is provided, but system complexity increases

Engineering Contradiction:
Improveparking assistance accuracyVSAvoidsystem configuration
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical/storage-based system (external RAM/ROM for storing patterns) with a computational system that calculates traveling traces in real-time using steering angle information and mathematical algorithms. This substitution maintains accuracy while reducing system complexity

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system transitions from static pre-stored patterns to dynamic real-time generation of traveling traces. The traveling traces are continuously updated based on current steering angle inputs, providing accurate parking assistance without requiring complex external storage infrastructure

Inventive Principle:
Principle #15Dynamics
