Solution Overview
Problem
Existing wearable health monitoring devices often compromise accuracy and comfort due to reliance on superficial body sites for temperature measurement, which are prone to interference and limit mobility, while deep body sites are cumbersome and inconvenient.
Innovation Solution
A wearable device utilizing an artificially created cavity, such as an ear piercing, to measure core body temperature through a sensor placed within the cavity, providing continuous and accurate temperature monitoring without interfering with daily activities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wearable devices measure temperature on skin surface, then accessibility and ease of operation are improved, but measurement precision deteriorates due to interference from ambient factors
Solution Approach 1:
The patent uses an artificial cavity (piercing) as an intermediary structure to place the temperature sensor away from the skin surface. This mediator allows the sensor to access a protected body site that is neither superficial nor requiring invasive deep body insertion, thus resolving the contradiction between ease of operation and measurement precision.
2Ease of operation
If wearable devices are placed on skin surface, then ease of operation is improved, but reliability deteriorates due to interference from perspiration and ambient air circulation
Solution Approach 1:
The artificial cavity serves as a protective intermediary environment that shields the sensor from harmful external factors like perspiration and ambient air circulation. This allows the device to maintain high reliability while remaining easy to operate, as the cavity is created through a simple piercing procedure.
3Measurement precision
If temperature sensors are placed in deep body sites, then measurement precision is improved, but device complexity and ease of operation worsen due to cumbersome placement
Solution Approach 1:
The artificial cavity created by piercing acts as an intermediary access route that simplifies the placement process compared to deep body site insertion. The cavity provides direct access to protected body tissues without requiring complex surgical procedures or specialized medical equipment, thus reducing device complexity while maintaining measurement precision.
4Measurement precision
If temperature sensors are placed in deep body sites, then measurement precision is improved, but ease of operation deteriorates due to limited mobility and inconvenience
Solution Approach 1:
The artificial cavity provides an intermediary location that combines the advantages of both superficial and deep body sites. It is accessible through a simple piercing procedure that does not limit mobility or require special setup, yet it protects the sensor from external interference and provides accurate core body temperature measurements, thus maintaining high user convenience.
