Solution Overview

Problem

Ultrasonic probes are vulnerable to external impacts, particularly wireless probes, which can damage internal components such as the array module, battery, and beamforming circuit, necessitating a solution to reduce impact transmission.

Innovation Solution

The ultrasonic probe incorporates an inner impact reducing member, comprising flexible circuit boards and elastic members, disposed between the acoustic module and electronic circuit to absorb and distribute impacts, and a head impact reducing member between the handle and head parts to further mitigate shocks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the ultrasonic probe is made wireless to improve ease of operation, then the ease of operation is improved, but the vulnerability to external impacts increases

Engineering Contradiction:
Improveease of operationVSAvoidvulnerability to external impacts
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent introduces an impact reducing member as an intermediary component between the acoustic module and electronic circuit. This mediator absorbs and dissipates impact energy, protecting the wireless probe's internal components from damage while maintaining the wireless design's operational ease.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent implements impact reducing members that provide beforehand cushioning by being pre-installed in positions that absorb potential impact forces. These components are positioned in advance to protect vulnerable parts (acoustic module, electronic circuit, battery) before any impact occurs, enabling wireless operation without compromising durability.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

2Ease of operation

If the cap is made from elastic rubber or TPE to improve ease of operation, then the ease of operation is improved, but the vulnerability to external impacts increases

Engineering Contradiction:
Improveease of operationVSAvoidstrength
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The patent employs composite material strategies by combining the elastic cap material (for ease of operation) with rigid protective housing and impact reducing members. This composite approach allows the cap to remain soft and easy to operate while the overall structure gains impact resistance through the combination of different material properties.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The impact reducing member acts as an intermediary between the soft cap and the internal electronic components. It transfers and dissipates impact energy that passes through the cap, preventing the cap's inherent softness from becoming a weakness in the overall structural strength.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If separate devices are added to reduce impact to the transducer, then the protection against impacts is improved, but the device complexity increases

Engineering Contradiction:
Improveprotection against impactsVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the impact reduction function with existing structural components of the ultrasonic probe. The impact reducing members are integrated into the housing structure and positioning elements, combining mechanical support and impact protection functions into unified components rather than adding separate protective devices.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The impact reducing members serve multiple functions: they provide mechanical support for the acoustic module, enable precise positioning, and reduce impact forces. This multi-functionality reduces the need for separate dedicated impact protection devices, maintaining simplicity while improving reliability.

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