Solution Overview
Problem
Elevator training environments lack a cost-effective and efficient method to emulate multiple AC motor configurations, requiring multiple motors and setups, which is impractical and expensive.
Innovation Solution
A system using interchangeable cartridges and faceplates that interface with a base station to configure motor windings into various AC motor configurations, including 3-wire wye, 3-wire delta, 6-wire, 9-wire wye, 9-wire delta, 12-wire, 6-wire puzzle, and 12-wire puzzle configurations, allowing a single motor to represent multiple configurations and simulate faults like open windings and missing leads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple AC motors and setups are used to emulate different motor configurations, then training completeness and configuration variety are improved, but cost and device complexity increase significantly
Solution Approach 1:
A single motor setup is designed to perform multiple functions by accommodating different wiring configurations (3-wire delta, 6-wire delta, 12-wire delta, 3-wire wye, 6-wire wye, 12-wire wye, and puzzle configurations) through interchangeable components. The universal base station with standardized receptacles and lead connections allows one motor to replace multiple dedicated motor setups, achieving configuration variety without proportional increases in device complexity.
Solution Approach 2:
The motor emulation system is divided into separable components: a permanent base station with lead connections and receptacles, interchangeable cartridges containing motor windings, and configurable faceplates. This segmentation allows individual components to be swapped independently, enabling different motor configurations to be assembled from the same base components rather than requiring complete separate setups for each configuration type.
2Adaptability or versatility
If multiple AC motors and setups are used to emulate different motor configurations, then training completeness is improved, but cost increases significantly
Solution Approach 1:
The system achieves training completeness for all major AC motor configurations using a single motor setup rather than requiring multiple expensive motor purchases. The universal base station with standardized interfaces allows one motor to serve multiple training purposes across different wiring configurations, significantly reducing the quantity of equipment needed and associated costs.
Solution Approach 2:
Instead of acquiring multiple physical motors, the system creates functional copies of different motor configurations through wiring arrangements. The cartridges and faceplates replicate the electrical characteristics of various motor types (delta, wye, puzzle configurations) without requiring actual multiple motors, providing cost-effective training equivalents.
3Device complexity
If a single motor is used to represent multiple configurations, then cost and device complexity are reduced, but adaptability and configuration variety decrease
Solution Approach 1:
The system transforms a static single-motor setup into a dynamic multi-configuration system through interchangeable cartridges and faceplates. Each cartridge can be inserted or removed to change the motor winding configuration, and faceplates can be adjusted to expose different lead connections. This dynamic reconfigurability allows one physical motor to adapt to multiple training scenarios without increasing overall device complexity.
Solution Approach 2:
Interchangeable cartridges and faceplates serve as intermediaries between the single motor and the various desired configurations. These intermediary components translate the single motor's capabilities into multiple configuration options, allowing the motor to represent different motor types (delta, wye, puzzle) without requiring the motor itself to be physically modified for each configuration.
4Adaptability or versatility
If multiple motors are used to provide comprehensive training scenarios, then training effectiveness is improved, but ease of operation and management become more difficult
Solution Approach 1:
By segmenting the training system into a permanent base station and interchangeable cartridges, the patent simplifies operation. Instructors and students only need to learn one base station interface and can swap pre-configured cartridges for different training scenarios, rather than managing multiple complete motor setups with different wiring and controls. This segmentation makes the system easier to operate while maintaining comprehensive training capabilities.
