Solution Overview

Problem

Motorcycles lack driver assistance systems and sensors to detect surroundings, making it difficult for drivers to recognize dangerous situations and preventing potential collisions, especially in tight spaces like alleys and heavy traffic.

Innovation Solution

A method and device that use cameras, ultrasonic sensors, and radar to map the motorcycle's environment, predict changes in open spaces, and evaluate trajectories for conflicts, providing alternative conflict-free paths to the driver through visual, haptic, and acoustic signals, ensuring safe navigation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If motorcycles are equipped with sensors and display systems to detect surroundings and provide driving instructions, then the rider's safety and situation awareness are improved, but the device complexity and cost increase

Engineering Contradiction:
ImprovesafetyVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple sensor types (cameras, ultrasonic sensors, radar) into an integrated sensing system that collectively detects the motorcycle's surroundings. This merging approach improves comprehensive situation awareness while sharing processing resources, thereby enhancing safety without proportionally increasing device complexity

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The display system serves multiple functions: it shows detected open spaces, displays alternative trajectories, provides conflict warnings, and presents driving instructions. This multi-functionality allows a single display system to deliver comprehensive safety information without requiring separate devices for each function, thus improving safety while controlling device complexity

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Measurement precision

If the motorcycle uses multiple sensors (cameras, ultrasonic sensors, radar) to detect the environment, then the measurement precision and detection capability are improved, but the use of energy and device complexity increase

Engineering Contradiction:
Improvedetection capabilityVSAvoidenergy consumption
Core Design Contradiction:
Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The system dynamically adjusts sensor activation and data processing based on the motorcycle's operating conditions. For example, different sensor combinations are activated depending on speed, environmental conditions, and detected risk levels. This dynamic operation maintains high detection precision when needed while reducing energy consumption during normal riding conditions

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system processes sensor data at different levels of detail based on situation criticality. During normal riding, partial processing of sensor data maintains adequate detection capability while consuming less energy. When conflicts or dangerous situations are detected, the system intensifies processing to provide comprehensive alternative trajectories and warnings, using excessive action only when necessary

Inventive Principle:
Principle #16Partial or excessive action

3Ease of operation

If the system provides comprehensive driving instructions and alternative trajectories through display systems, then the ease of operation is improved, but the loss of time for processing and communicating information increases

Engineering Contradiction:
Improveease of operationVSAvoidprocessing time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The system pre-calculates and prepares alternative trajectories based on predicted changes in open spaces before conflicts actually occur. By performing preliminary analysis of potential dangerous situations and preparing escape routes in advance, the system reduces real-time processing time while maintaining comprehensive guidance capability when needed

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

When a conflict is detected, the system prioritizes and rapidly communicates only the most critical information to the rider - specifically the alternative trajectory and immediate action required. Less critical detailed information is either omitted or provided in abbreviated form, allowing the system to maintain ease of operation through rapid information delivery rather than comprehensive but time-consuming communication

Inventive Principle:
Principle #21Skipping (Rushing through)
