Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a utilization management system is introduced to control and optimize resource allocation, then resource utilization efficiency is improved, but system complexity and implementation costs increase
Solution Approach 1:
The patent introduces a utilization management system as an intermediary layer between resource providers and consumers. This system includes a utilization control device that mediates resource allocation decisions, collecting utilization information from multiple sources and making coordinated allocation decisions. The intermediary structure enables optimized resource utilization without requiring direct complex interactions between all stakeholders.
Solution Approach 2:
The utilization management system is segmented into distinct functional modules: a utilization information collection unit that gathers data from multiple sources, a utilization control device that processes this information, and various execution units that implement allocation decisions. This segmentation allows the complex system to be managed through modular, independent components with specific responsibilities.
2Measurement precision
If comprehensive utilization information is collected from multiple sources to make accurate allocation decisions, then allocation accuracy is improved, but information processing time and computational load increase
Solution Approach 1:
The system performs preliminary actions by continuously collecting and pre-processing utilization information from multiple sources before allocation decisions are needed. The utilization information collection unit gathers data in advance from resource monitoring devices, user preferences, and historical usage patterns, preparing this information for rapid processing when allocation decisions are required.
Solution Approach 2:
The system implements feedback mechanisms where utilization information is continuously collected from resource monitoring devices and user devices, processed by the utilization control device, and used to adjust subsequent allocation decisions. This feedback loop enables the system to learn from past allocations and improve accuracy over time while maintaining efficient processing through iterative refinement.

AI summary
According to the present invention, the convenience of a utilization management technology for a usage target object is enhanced and the security risk is reduced. This utilization control device (1) is capable of communicating only in a near field communication (63) and stores a first public key that is paired with a first secret key stored in a management device (2) . When hole data is received with a first signature from a provider terminal (3), the first signature is verified by means of the first key, and when the signature verification is established, the hole data is set to an own device (1). The hole data includes a second public key that is paired with a second secret key stored in the management device (2). When a utilization permit card is received with a second signature from a user terminal (4), the second signature is verified with the second public key, and when the signature verification is validated, transaction information included in the utilization permit card is acquired. In addition, with reference to the acquired transaction information, when a condition specified by the transaction information is satisfied, a utilization limit to the object to be utilized (a house (50)) is released.
