Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication methods for autonomous vehicles and robots fail to simultaneously meet low communication costs and communication delay requirements, as either cost reduction or delay satisfaction is compromised in previous solutions.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the cheapest communication network is selected to reduce communication cost, then communication cost is reduced, but communication delay requirement cannot be satisfied
Solution Approach 1:
The patent implements dynamic communication device selection based on real-time movement route and communication environment. The terminal determines communication quality and costs for multiple devices, then dynamically selects the optimal device considering both cost and delay requirements, rather than statically choosing the cheapest option. This dynamic adaptation allows the system to switch between cost-optimized and delay-optimized communication devices based on current conditions.
Solution Approach 2:
The system changes the selection criteria parameter from purely cost-based to a composite parameter that includes both communication cost and communication quality (delay). By modifying the decision parameter to consider multiple factors simultaneously, the system resolves the contradiction between minimizing cost and satisfying delay requirements.
2Loss of time
If communication networks are selected based on communication quality and delay requirements, then communication delay requirement is satisfied, but communication cost increases
Solution Approach 1:
The system dynamically adjusts the balance between communication quality and cost based on the movement route and environmental conditions. Rather than always prioritizing delay satisfaction, the terminal adaptively selects communication devices that optimize the cost-delay trade-off, using cheaper networks when they meet requirements and switching to premium networks only when necessary.
Solution Approach 2:
The system applies partial action by selecting communication devices that provide sufficient (but not excessive) communication quality to meet requirements. Instead of always choosing the highest quality (most expensive) option, it selects the minimum necessary quality level that satisfies delay requirements, thereby reducing cost.
3Loss of energy
If the terminal waits for a cheaper communication network to become available, then communication cost is reduced, but communication cannot start timely
Solution Approach 1:
The terminal performs preliminary determination of communication quality and costs for multiple communication devices before actual communication begins. By pre-assessing the available options and their characteristics, the system can make informed selection decisions without delaying communication startup, resolving the contradiction between cost optimization and timely communication initiation.
4Loss of energy
If multiple communication devices are managed with route-based planning, then communication cost and delay requirements can be balanced, but device complexity increases
Solution Approach 1:
The communication management function is segmented into distinct modules: movement route management unit, communication environment information management, and communication device selection unit. This segmentation allows complex multi-factor optimization to be broken down into manageable components, reducing overall system complexity while enabling sophisticated communication device selection based on route and environmental factors.
