Solution Overview

Problem

Existing measurement devices face challenges in managing encryption information efficiently when paired with multiple information terminals due to limited storage capacity, often leading to unintended deletion of encryption information.

Innovation Solution

A measurement device that associates user information with encryption information in its storage, allowing for user-specific management and editing of encryption information, enabling appropriate handling of limited storage capacity and facilitating secure communication with multiple terminals.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the measurement device stores encryption information for multiple information terminals, then the device can communicate with more terminals, but the storage capacity is exceeded and existing encryption information must be deleted

Engineering Contradiction:

Improvenumber of paired terminalsVSAvoidstorage capacity

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent segments the storage of encryption information by associating it with user information. Instead of storing encryption information in a unified pool, the system creates separate storage entries tied to specific users, allowing selective retention and management of encryption information based on user associations rather than simply filling storage slots sequentially.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces dynamic management of encryption information through user-based association. The system can dynamically determine which encryption information to retain or delete based on the current user's identification, allowing flexible adaptation when a new terminal pairs with the measurement device without rigid storage constraints.

Inventive Principle:

Principle #15Dynamics

2Quantity of substance

If the measurement device deletes oldest encryption information to make space for new terminals, then storage capacity is maintained, but the deletion is unintentional and inconvenient for users

Engineering Contradiction:

Improvestorage capacityVSAvoiduser convenience

Core Design Contradiction:

Quantity of substanceVSEase of operation

Solution Approach 1:

The patent implements feedback mechanisms where the measurement device identifies the current user through user information received from the information terminal. This feedback loop allows the system to understand which encryption information corresponds to the current user and preserve it, preventing unintentional deletion of relevant encryption data while managing storage capacity.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system performs self-service by automatically identifying the current user and selectively retaining encryption information associated with that user. This eliminates the need for manual user intervention to preserve important encryption data, as the system autonomously determines what to keep based on user identification feedback.

Inventive Principle:

Principle #25Self-service

3Adaptability or versatility

If the measurement device associates encryption information with user information, then user-specific management is enabled, but the system complexity increases

Engineering Contradiction:

Improveuser-specific management capabilityVSAvoidstorage management complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges the management of encryption information with user information storage. Instead of treating encryption information as separate entities that require independent tracking, the system combines them into unified user-associated records, simplifying the overall management process while enabling user-specific control.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent creates a universal storage structure where user information serves multiple functions: identifying the current user, determining which encryption information to retain, and managing pairing relationships. This multi-functional approach reduces the need for separate complex management systems for each function.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A measurement device includes: a short-range wireless communication interface; a processor; and a storage. In a state where a communication connection with an information terminal using short-range wireless communication is established, the processor receives, from the information terminal, user information specifying a user of the information terminal, shares, with the information terminal, encryption information for performing encryption communication using short-range wireless communication, and stores the encryption information and the user information in the storage in association with each other.
