Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If no reservation system is used, then the point of interest can operate with simpler procedures, but wait times become unmanageable and customers are lost

Engineering Contradiction:
Improvesimpler proceduresVSAvoidwait times
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The system performs preliminary actions by collecting occupancy data in advance and using machine learning models to predict future wait times before customers arrive. This allows the point of interest to prepare for expected crowd levels without requiring advance reservations, maintaining operational simplicity while managing wait times proactively.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements continuous feedback loops where occupancy signals from sensors are constantly monitored, analyzed by machine learning models, and used to update predictions. This feedback mechanism enables real-time adjustments to operational strategies based on actual crowd patterns, balancing simplicity with effective wait time management.

Inventive Principle:
Principle #23Feedback

2Device complexity

If wait time information is not provided to customers, then the system remains simple, but customers cannot make informed decisions and may leave due to long waits

Engineering Contradiction:
Improvesystem simplicityVSAvoidwait time information
Core Design Contradiction:
Device complexityVSLoss of information

Solution Approach 1:

The system introduces an intermediary layer consisting of machine learning models and prediction algorithms that process raw occupancy data and transform it into useful wait time estimates for customers. This intermediary handles the complexity of data analysis while presenting simplified, actionable information to end users, maintaining system simplicity from the customer perspective.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces manual wait time estimation methods with automated machine learning-based prediction systems. This substitution handles the computational complexity internally while providing customers with accurate wait time information through simple digital interfaces, reducing perceived system complexity while improving information quality.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Measurement precision

If occupancy monitoring is implemented, then wait time predictions become accurate, but the system requires additional sensors and data infrastructure

Engineering Contradiction:
Improvewait time prediction accuracyVSAvoidsensors and data infrastructure
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system employs multi-functional occupancy sensors that serve multiple purposes: tracking current occupancy levels, detecting customer flow patterns, and providing data for machine learning training. This universal approach maximizes the utility of each sensor deployed, improving measurement precision while minimizing the overall infrastructure required compared to specialized dedicated sensors for each function.

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

AI summary

A method of determining a wait time at a point of interest includes obtaining a current occupancy signal of a parking establishment associated with one or more points of interest, obtaining a historic occupancy signal of the parking establishment, determining, with one or more processors, a predicted wait time for the one or more points of interest associated with the parking establishment based on the current occupancy signal and the historic occupancy signal, and communicating the predicted wait time to a user with a user interface device.
