Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical devices, such as automated Transcranial Doppler (TCD) probes, face safety concerns due to inadequate monitoring of pressure or force exerted on a patient's skull during placement, leading to potential discomfort and suboptimal manual or automated alignment.
Innovation Solution
An integrated probe structure incorporating a probe with a load cell and gimbal hub, which includes a cavity for receiving the probe and load cell, allowing for detection of forces exerted along multiple axes and adjusting pressure based on measured force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual placement of TCD probe is used, then ease of operation is improved, but measurement precision of force monitoring deteriorates
Solution Approach 1:
The patent combines the TCD probe with a load cell and gimbal structure into an integrated assembly. The load cell is positioned directly beneath the probe to measure forces, while the gimbal allows rotational movement. This merging of measurement and positioning functions into a single integrated structure enables both automated force monitoring and operational flexibility without requiring separate manual monitoring systems.
2Productivity
If automated robotic headset is used, then productivity is improved, but device complexity increases
Solution Approach 1:
The patent divides the probe system into distinct functional segments: the TCD probe element, the load cell for force measurement, the gimbal for rotational positioning, and the housing structure. This segmentation allows each component to perform its specific function independently while being integrated into an automated system, managing complexity through modular functional division.
Solution Approach 2:
The integrated probe structure serves multiple functions simultaneously: the load cell measures forces in multiple directions, the gimbal provides rotational freedom for positioning, and the housing protects all components. This multi-functionality reduces the need for separate systems, thereby managing overall device complexity while maintaining automated capabilities.
3Measurement precision
If integrated probe structure with load cell is used, then measurement precision of force is improved, but device complexity increases
Solution Approach 1:
The load cell is integrated directly into the probe structure rather than being a separate external device. The probe, load cell, and gimbal form a unified assembly where the load cell is positioned immediately beneath the probe to directly measure applied forces. This merging minimizes the number of separate components and simplifies the overall structure while maintaining high measurement precision.
