Solution Overview

Problem

Medical measuring devices face a trade-off between user-friendliness and personal information protection, as existing solutions that prevent unauthorized access, such as requiring a release code, deteriorate user experience by increasing the time needed to start measurements, especially in environments where multiple patients' data needs to be accessed quickly.

Innovation Solution

A medical measuring device with a biosensor, recording component, and information protection component that determines whether to allow readout of personal information data, using a combination of wireless communication, movement detection, and radio wave intensity to assess the device's location and usage context, thereby controlling access and maintaining usability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a release code is required to start using the medical measuring device, then personal information protection is improved, but user-friendliness deteriorates due to increased time needed to start measurements

Engineering Contradiction:

Improvepersonal information protectionVSAvoiduser-friendliness

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The device automatically determines whether to prohibit readout of personal information data based on its own location and usage context without requiring manual intervention. The information protection component autonomously makes decisions using wireless communication status and movement detection, eliminating the need for users to manually input release codes while maintaining security.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The manual mechanical action of entering a release code is replaced by automated electronic detection systems. Wireless communication status detection and movement sensors automatically provide the information protection component with context data, substituting the manual input process with automated electronic assessment of usage environment.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If a release code is input each time the device is powered on, then personal information protection is improved, but measurement efficiency deteriorates in environments with multiple patients

Engineering Contradiction:

Improvepersonal information protectionVSAvoidmeasurement efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The device performs preliminary detection of wireless communication status and movement context as soon as it is powered on, before requiring any user operations. This preliminary action automatically establishes the usage context, allowing the information protection component to make immediate decisions about data access without delaying measurement operations.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The device autonomously manages the balance between security and efficiency by self-determining the appropriate data access restrictions based on its location and usage context. This eliminates the need for manual release code input while maintaining personal information protection, thereby preserving measurement efficiency in multi-patient environments.

Inventive Principle:

Principle #25Self-service

3Adaptability or versatility

If personal information data is stored in the device, then data management capability is improved, but risk of data leakage to outsiders increases when the device is taken out without permission

Engineering Contradiction:

Improvedata management capabilityVSAvoiddata leakage risk

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The information protection component continuously monitors wireless communication status and movement context, using this feedback to dynamically adjust data access permissions. When the device detects being taken out of the authorized environment (through changes in wireless status or movement patterns), it automatically prohibits readout of personal information data, creating a feedback-based security response.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

Physical possession of the device is replaced as the sole control mechanism with electronic detection systems. Wireless communication status detection and movement sensors provide automated feedback about the device's environment, substituting manual physical control with electronic assessment that triggers appropriate security responses.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
