Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing cloud-based medical information storage systems automatically delete medical information of deceased patients after a certain time, rendering valuable medical condition information inaccessible for future medical examinations or treatments.

Innovation Solution

A management server system that identifies deceased patients' medical information, extracts and separates relevant medical condition information, and stores it separately, allowing for retrieval and display upon request while deleting the original patient data to conserve memory space.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If medical information of deceased patients is automatically deleted after a certain time, then memory space is conserved, but valuable medical condition information becomes inaccessible for future medical use

Engineering Contradiction:

Improvememory spaceVSAvoidmedical condition information accessibility

Core Design Contradiction:

Quantity of substanceVSLoss of information

Solution Approach 1:

The patent segments medical information into two distinct categories: identifiable information (patient name, ID, contact details) and medical condition information (diagnosis, treatment history, cause of death). By segmenting the data structure, the system can selectively delete identifiable information while preserving medical condition information, thus resolving the contradiction between memory conservation and information accessibility.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent extracts and separates medical condition information from the general medical information database. This extracted information is stored in a dedicated memory region that is not subject to automatic deletion. This extraction allows the system to maintain valuable medical knowledge while freeing up space by removing only the temporary identifiable information.

Inventive Principle:

Principle #2Taking out (Extraction)

2Device complexity

If all medical information is deleted after a certain time, then data management is simplified, but medical condition information needed for family members' treatment is lost

Engineering Contradiction:

Improvedata management complexityVSAvoidmedical condition information for family members

Core Design Contradiction:

Device complexityVSLoss of information

Solution Approach 1:

The patent implements segmentation by creating separate storage areas for different types of information. The medical condition information is stored in a dedicated region with extended retention policies, while identifiable information is stored separately and subject to deletion. This segmentation simplifies data management by providing clear rules for different data types while preserving critical information for family members.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent applies local quality by implementing different retention policies for different parts of the data structure. Medical condition information retains long-term accessibility for family members, while identifiable information has limited retention. This differentiated approach simplifies management by applying specific quality attributes (retention duration) to specific data regions based on their unique requirements.

Inventive Principle:

Principle #3Local quality

3Loss of information

If medical information is retained indefinitely, then complete medical history is available, but memory space is consumed by unnecessary data

Engineering Contradiction:

Improvemedical history completenessVSAvoidmemory space consumption

Core Design Contradiction:

Loss of informationVSQuantity of substance

Solution Approach 1:

The patent segments medical information into essential medical condition data and temporary identifiable information. By segmenting the data, the system can retain medical history completeness for family members while deleting unnecessary identifiable data after a certain period, thus optimizing memory space utilization.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent extracts and preserves medical condition information in a dedicated storage region that is not subject to automatic deletion. This extraction ensures that valuable medical history remains accessible while allowing the system to delete and reuse memory space for other purposes, balancing completeness with space efficiency.

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

The management server includes: a storage that stores medical information including patient-identity-specific information; and a processor coupled to the storage. The processor: receives patient-identity-specific information of a deceased patient; retrieves a deceased patient medical information; determines whether the deceased patient medical information includes a predetermined information that specifies a medical condition of the deceased patient; upon determining that the deceased patient medical information does not include the predetermined information, deletes the deceased patient medical information from the storage; upon determining that the deceased patient medical information includes the predetermined information: extracts the predetermined information along with the patient-identity-specific information of the deceased patient from the deceased patient medical information; separately stores the extracted predetermined information and the patient-identity-specific information of the deceased patient in the storage as a medical condition information; and deletes the deceased patient medical information after the extraction and storage of the medical condition information.
