Solution Overview

Problem

The existing methods for aligning ultrasonic detectors are inefficient and imprecise, often relying on trial and error, which can lead to coarse and inaccurate alignment, especially when using a group of receivers to optimize the positioning of ultrasonic transmitters in various configurations.

Innovation Solution

A method and system utilizing a receiver with a plurality of transducers arranged in a continuous line, processed by a single unit, to provide precise alignment indications, allowing for accurate adjustment of the transmitter's orientation and position by identifying the transducer receiving the ultrasonic wave, thus enabling quicker and more precise alignment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If trial and error method is used to align the transmitter, then the alignment can be achieved, but the alignment precision is coarse and inaccurate

Engineering Contradiction:
Improvealignment precisionVSAvoidalignment time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent replaces the mechanical trial-and-error adjustment method with an acoustic field-based detection system. The receiver detects ultrasonic waves from multiple transmitters simultaneously, and a processing unit calculates precise spatial positions and orientations, substituting manual mechanical adjustment with automated acoustic field measurement and computational analysis.

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

Solution Approach 2:

The patent introduces a receiver and processing unit as intermediaries between the transmitters and the alignment process. The receiver captures ultrasonic signals, and the processing unit computes alignment parameters, serving as a mediator that translates acoustic field information into precise alignment data without requiring direct mechanical intervention.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If a group of receivers is used to align the transmitter, then the alignment coverage is improved, but the indication precision remains coarse due to large spacing between receivers

Engineering Contradiction:
Improvealignment indication precisionVSAvoidreceiver arrangement complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent inverts the traditional alignment approach by having multiple transmitters emit signals toward a single receiver, rather than having multiple receivers detect signals from one transmitter. This inversion allows the receiver to receive signals from different spatial positions simultaneously, providing fine-grained alignment information without requiring multiple receivers spaced closely together.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The patent uses multiple transmitters that copy the same ultrasonic signal pattern but from different spatial positions. By analyzing the relative timing and intensity of these copied signals at the receiver, the system can precisely determine the receiver's position and orientation without requiring the receivers to be densely arranged.

Inventive Principle:
Principle #26Copying

3Measurement precision

If multiple receivers are used to improve alignment accuracy, then the measurement coverage increases, but the system complexity and cost increase

Engineering Contradiction:

Core Design Contradiction:

Solution Approach 1:

The patent inverts the traditional alignment approach by having multiple transmitters emit signals toward a single receiver, rather than having multiple receivers detect signals from one transmitter. This inversion allows the receiver to receive signals from different spatial positions simultaneously, providing fine-grained alignment information without requiring multiple receivers spaced closely together.
