Solution Overview

Problem

Existing ultrasonic transducer devices face challenges in securely and simply setting unique IDs for identification, as methods involving electronically rewritable memory increase costs and risk manipulation, while circuit adjustments for operation/non-operation states are complex and prone to modification.

Innovation Solution

Incorporating an identification ultrasonic transducer element array where some elements are set to a receivable state and others to a non-receivable state, using substrate openings and vibration suppression materials, allowing for secure and simple hardware-based ID setting, with separate signal lines for each state to prevent mixing of outputs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If electronically rewritable memory (RAM or EEPROM) is provided to store probe ID, then probe identification is enabled, but cost increases and the probe ID can be easily rewritten by a third party

Engineering Contradiction:
ImproveProbe ID securityVSAvoidManufacturing cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The probe ID is segmented into multiple bits, where each bit corresponds to the operational state (receivable or non-receivable) of a specific ultrasonic transducer element. This segmentation allows the ID to be encoded in the physical configuration of the device rather than stored in memory, eliminating the need for expensive and vulnerable electronic storage while maintaining security and enabling straightforward manufacturing.

Inventive Principle:
Principle #1Segmentation

2Reliability

If circuit adjustment is used to set operation/non-operation state for probe ID, then unique identification is achieved, but the circuit may be modified afterwards and individual adjustment is required

Engineering Contradiction:
ImproveProbe ID stabilityVSAvoidCircuit adjustment complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The ultrasonic transducer elements themselves serve the dual function of both performing their primary measurement function and encoding the probe ID through their operational states. This self-service approach eliminates the need for separate circuit adjustment mechanisms, as the ID is inherently embedded in the functional configuration of the transducer array, preventing unauthorized modification and simplifying the overall device structure.

Inventive Principle:
Principle #25Self-service
