Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a camera on the portable communications terminal is used to determine distance, then measurement precision is improved, but device complexity increases

Engineering Contradiction:
Improvedistance determination accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent introduces an intermediary processing system that includes image capture components, image processing algorithms, and coordinate system transformation mechanisms. This intermediary layer translates complex image data into accurate distance measurements, resolving the contradiction by adding controlled complexity to achieve precision without requiring the entire system to become unnecessarily complex.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces traditional mechanical or sensor-based distance measurement systems with an optical imaging system. By using camera-based image analysis and computational methods to determine distance, the system achieves high measurement precision while avoiding the complexity of multiple mechanical sensors or sophisticated hardware configurations.

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

2Reliability

If distance determination is continuously monitored, then reliability is improved, but use of energy increases

Engineering Contradiction:
Improvesafety monitoring reliabilityVSAvoidenergy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent implements periodic distance monitoring through the camera system, capturing images at defined intervals or triggered by specific events during maneuvering operations. This periodic action maintains reliable safety monitoring by continuously checking distance thresholds while consuming energy only when necessary, rather than operating continuously.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system incorporates feedback mechanisms where distance measurement results trigger appropriate responses. When the vehicle is detected outside the defined distance threshold, the system provides feedback to interrupt or alert the user, maintaining high reliability for safety-critical conditions while optimizing energy usage by activating full monitoring only when needed.

Inventive Principle:
Principle #23Feedback

AI summary

The invention relates to a method for maneuvering a motor vehicle (1). In the method, the maneuvering process of the motor vehicle (1) is carried out by a user (3), who is positioned outside of the motor vehicle (1) in the region surrounding the motor vehicle (1), using a portable communication terminal (4), and signals are exchanged between the communication terminal (4) and the motor vehicle (1) for this purpose. The distance (A) between the motor vehicle (1) and the portable communication terminal (4) is determined, wherein the motor vehicle (1) is at least partly captured by a camera (7) of the portable communication terminal (4) during the maneuvering process, and the distance (A) between the motor vehicle (1) and the communication terminal (4) is determined on the basis of the captured image information. The invention also relates to a maneuvering assistance system (6).
