Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If mechanical cabling system with knobs is used to control TEE probe, then device structure is simple and reliable, but ease of operation deteriorates due to cumbersome and unintuitive control

Engineering Contradiction:
Improveease of operationVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical cabling system with knobs with an electronic system featuring a touch interface and capacitive sensors. The control panel with capacitive sensors detects finger proximity and touch inputs, eliminating the need for mechanical knobs and cables. This substitution improves ease of operation by providing intuitive touch-based control while managing device complexity through electronic integration.

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

Solution Approach 2:

The patent changes the control interface from mechanical (knobs) to electronic (capacitive touch sensors). The capacitive sensors detect changes in electrical parameters (capacitance) when a finger approaches or touches the screen, enabling control without physical mechanical components. This parameter change from mechanical to electrical control improves usability while maintaining system functionality.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If TEE probe is inserted without bite block protection, then ease of operation improves, but object-affected harmful factors worsen due to risk of bite and anteflexion/retroflexion movement

Engineering Contradiction:
ImprovereliabilityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The bite block is designed to be placed in the patient's mouth before probe insertion. It preliminarily establishes protection against biting and prevents anteflexion/retroflexion movements during the insertion process. This preliminary protective measure ensures safety and reliability before the actual probing begins, without requiring complex active control systems.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The bite block serves as an intermediary device between the patient's teeth and the TEE probe. It physically intermediates the interaction, preventing direct contact between teeth and probe that could cause biting damage or unwanted flexion. This simple mechanical intermediary provides reliable protection without adding complex control mechanisms.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If fixed probe design is used, then manufacturing precision is maintained, but adaptability deteriorates due to inability to accommodate different patient needs

Engineering Contradiction:
ImproveadaptabilityVSAvoidmanufacturing precision
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The TEE probe is divided into separable components: a reusable handle unit and disposable probe cables. The handle contains the electronics and control interface, while the cable with transducer can be replaced. This segmentation allows the system to maintain precision in the reusable components while adapting to different patients through disposable cables, combining manufacturing precision with adaptability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The handle unit is designed as a universal component that can work with multiple different probe cables. The standardized interface allows one handle to accommodate various cable types and lengths, making the system adaptable to different patient needs while maintaining manufacturing precision in the standardized components. This multi-functionality enables versatility without compromising precision.

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

AI summary

An ultrasound probe and a ultrasound system are disclosed. In some embodiments, the ultrasound system includes a bite block configured to, during a transesophageal insertion of the probe cable starting from the distal end, guard the probe cable from a bite and prevent anteflexion and retroflexion movement of the transducer until a predetermined length of the probe cable is inserted.
