Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users often cannot receive necessary sensing data due to the absence of providers with installed sensors capable of obtaining specific data, such as traffic situation data at intersections, leading to reduced utilization of sensor network systems.
Innovation Solution
A sensing data distribution system that includes mobile objects with attached sensing devices, which can generate and provide sensing data even if no sensor is installed at the required location, by storing run operation information and device attributes, and outputting provision data catalogues to match user requests with available sensing data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If sensors are installed at fixed locations to provide sensing data, then the sensing data can be obtained at specific positions, but sensing data cannot be provided at locations where no sensor is installed
Solution Approach 1:
The patent applies the dynamics principle by transitioning from static fixed sensors to dynamic mobile sensors. Mobile objects equipped with sensors move through different locations, dynamically providing sensing data coverage to multiple positions without requiring permanent sensor installation at each location. This resolves the contradiction by making the sensing system adaptable to various locations while avoiding the complexity of installing sensors everywhere.
Solution Approach 2:
The patent applies the universality principle by using mobile objects that can serve multiple functions: they act as both transport vehicles and mobile sensing platforms. A single mobile object can provide sensing data for multiple different locations during its movement, making the sensing system universally applicable across different positions without requiring location-specific sensor installations.
2Adaptability or versatility
If mobile objects with sensors are used to provide sensing data at multiple locations, then sensing data coverage is improved, but management and coordination complexity increases
Solution Approach 1:
The patent applies the intermediary principle by introducing a management server as a mediator between mobile objects and users. The management server handles the complexity of coordinating multiple mobile sensors, matching sensor capabilities with user requests, and routing data flows. This intermediary absorbs the management complexity while enabling mobile sensors to provide adaptable sensing data coverage.
Solution Approach 2:
The patent applies the feedback principle by implementing a metadata-based matching system where sensor capabilities, user requests, and data flow instructions are continuously exchanged through the management server. The system receives feedback about sensor availability and user needs, dynamically adjusting data provision to optimize both coverage and management efficiency.
3Ease of operation
If providers install sensors only for their own use, then the provider's specific needs are met, but other users cannot access the sensing data even if the sensor is available
Solution Approach 1:
The patent applies the universality principle by enabling mobile sensors to serve multiple users across different applications. A sensor mounted on a mobile object can provide data to multiple users with different needs, making the sensing resource universally useful rather than dedicated to a single provider's purpose.
Solution Approach 2:
The patent applies the self-service principle through automated metadata registration and matching. The system automatically registers sensor capabilities, matches them with user requests, and establishes data sharing without requiring manual intervention from providers. This enables seamless data accessibility while preventing information loss through automated resource utilization.
