Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple physical infrastructure resources such as antenna devices are installed to support new communication standards like 5G, then wireless communication capability is improved, but investment cost and operational cost increase

Engineering Contradiction:
Improvewireless communication capabilityVSAvoidphysical infrastructure resources
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The patent implements RAN sharing by merging multiple physical infrastructure resources (antenna devices, base stations) into shared infrastructure that can be jointly utilized by multiple network operators. The management control device coordinates frequency band allocation and communication control among different operators, enabling cost reduction while maintaining communication capability through resource sharing rather than separate dedicated infrastructure for each operator.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent creates a universal infrastructure system where physical resources serve multiple functions and multiple operators simultaneously. The frequency management database and management control device enable the same physical antenna and base station resources to support various network operators and communication services, transforming dedicated infrastructure into multi-functional shared infrastructure.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Productivity

If frequency bands are allocated to multiple users simultaneously, then resource utilization efficiency is improved, but interference between users increases

Engineering Contradiction:
Improveresource utilization efficiencyVSAvoidinterference between users
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent implements dynamic frequency band allocation where the management control device continuously adjusts frequency assignments based on real-time communication conditions, user locations, and interference levels. The system dynamically reconfigures frequency allocations to optimize resource utilization while managing interference, rather than using static fixed allocations.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The frequency management database and management control device utilize feedback mechanisms to monitor communication quality, interference levels, and resource usage. Based on this feedback, the system adjusts frequency band allocations and communication parameters to maintain efficient resource utilization while controlling interference between multiple users.

Inventive Principle:
Principle #23Feedback

3Adaptability or versatility

If identification information from multiple sources is linked in the frequency management database, then sharing flexibility is improved, but system complexity increases

Engineering Contradiction:
Improvesharing flexibilityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces the management control device as an intermediary component that handles the complexity of linking identification information from multiple sources (terminal devices, users, frequency management database). This intermediary layer abstracts the complexity of multi-source data integration from individual components, enabling flexible sharing while managing system complexity through centralized coordination.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Measurement precision

If third-type identification information is generated and managed, then frequency band allocation precision is improved, but information management complexity increases

Engineering Contradiction:
Improvefrequency band allocation precisionVSAvoidinformation management complexity
Core Design Contradiction:
Measurement precisionVSLoss of information

Solution Approach 1:

The patent segments identification information into three distinct types: first-type identification information (terminal device specific), second-type identification information (user specific), and third-type identification information (combination for frequency allocation). This segmentation allows precise frequency band allocation by linking specific terminal and user identifiers, while managing complexity through structured information organization rather than monolithic data handling.

Inventive Principle:
Principle #1Segmentation

AI summary

[Problem] To implement RAN sharing as well as frequency sharing in a more preferred form. [Solution] A management device includes an obtaining unit that obtains, from a communication control device, first-type identification information which is specific to each communication device that performs wireless communication with one or more terminal devices, and second-type identification information which is specific to a user who is the target for allocation of a frequency band that is available for secondary use in the wireless communication; a generating unit that generates third-type identification information which is specific to the combination of the obtained first-type identification information and the obtained second-type identification information and which is meant for allocating the frequency band to at least either the communication device or the user; and a notifying unit that notifies the communication control device about the generated third-type identification information.
