Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for identifying parking availability and enforcing parking regulations face challenges in providing reliable, real-time data and auditing capabilities, especially in urban areas where parking spaces are scarce and transaction frequencies may not accurately reflect occupancy.
Innovation Solution
A blockchain-based system that stores and distributes parking occupancy data, ensuring immutability and reliability by using a blockchain to record and verify the availability of parking spaces, allowing for secure and accurate identification of available spots and resolving disputes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If transactional data from merchants is used to estimate parking availability, then parking information can be distributed to drivers, but the reliability of parking availability data deteriorates because transaction frequencies may not accurately reflect actual occupancy
Solution Approach 1:
The patent introduces a blockchain-based intermediary system that acts as a trusted mediator between parking space occupants and drivers. The blockchain ledger records verified occupancy data from multiple sources (merchant transactions, parking enforcement observations, sensor data) and provides an immutable, tamper-proof record that drivers can trust. This intermediary resolves the contradiction by decoupling the estimation process from the final reliability assessment - while initial data may be estimative, the blockchain verification process ensures ultimate reliability through cryptographic proof and multi-source validation.
2Productivity
If more parking spaces are made available in urban areas, then driver parking needs are better met, but the complexity of managing and monitoring parking occupancy increases
Solution Approach 1:
The blockchain system serves multiple functions simultaneously: it records occupancy data, verifies parking compliance, provides real-time availability information to drivers, and creates an immutable audit trail for enforcement. This multi-functional approach reduces overall system complexity by consolidating what would otherwise require separate systems into a single universal platform. The same blockchain ledger that tracks occupancy also serves as the verification mechanism for compliance and the information source for driver guidance.
Solution Approach 2:
The system enables self-service through automated blockchain validation and smart contracts that automatically verify parking compliance and update availability status without requiring manual intervention from enforcement officers or system administrators. The decentralized nature of blockchain allows each participant to independently verify occupancy status and enforce rules, reducing the operational complexity of managing expanded parking infrastructure.
3Measurement precision
If real-time parking occupancy data is tracked and distributed, then accurate parking availability information is provided to drivers, but the difficulty of detecting and measuring actual occupancy increases
Solution Approach 1:
The patent combines multiple occupancy detection methods (merchant transaction data, parking enforcement observations, sensor readings) into a single blockchain-recorded occupancy status. Rather than relying on a single difficult-to-implement detection system, the solution merges multiple data sources that are already in use, validating them through blockchain consensus mechanisms. This combination approach achieves high measurement precision by cross-validating multiple independent sources while avoiding the complexity of any single sophisticated detection system.
Data Source
AI summary
A method for distributing parking availability data via blockchain includes: storing a blockchain comprised of a plurality of blocks, each block having a block header including a timestamp; receiving spot availability notifications including a common spot identifier and availability data; generating a transaction value including the common spot identifier and availability data; generating a new block header including i) a current timestamp, ii) a reference hash value generated via hashing of the block header included in a most recent block identified via the timestamp, and iii) a transaction hash value generated via hashing of the new transaction value; generating a new block comprised of the new block header and the new transaction value; and transmitting the generated new block.
