Solution Overview

Problem

Existing transportation systems for orbits, such as chairlifts and cable cars, have complex locking devices that require additional mechanisms for locking and releasing safety devices, leading to increased operational and economic costs.

Innovation Solution

A vehicle with an actuatable clamping device and a locking device that automatically transitions between locked and unlocked positions based on the clamping device's state, eliminating the need for additional locking mechanisms by integrating the locking function with the clamping device's operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a locking device with additional mechanisms is used to lock and release safety devices, then the safety device can be reliably locked during transport, but the device complexity and operational costs increase

Engineering Contradiction:
Improvesafety device locking reliabilityVSAvoidlocking device complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The locking device merges the locking function with the clamping device by using the clamping jaws' movement to directly actuate the locking mechanism. The locking lever is connected to the clamping device such that when clamping jaws close, they automatically lock the safety device, and when clamping jaws open, they automatically unlock the safety device. This eliminates the need for separate locking mechanisms and gates.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The clamping device is given multiple functions: it not only clamps the hoisting rope to propel the transportation device but also simultaneously locks and unlocks the safety device. The locking lever serves dual purposes by being actuated through the clamping device's movement, making the system more efficient and less complex.

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

2Reliability

If additional locking mechanisms and gates are installed to operate the locking device, then the safety device can be securely locked, but the manufacturing costs and operational expenses increase

Engineering Contradiction:
Improvesafety device lockingVSAvoidmanufacturing cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The invention combines the locking function into the existing clamping device structure. The locking lever is integrated with the clamping mechanism, using the same movement to both clamp the rope and lock the safety device. This eliminates the need for separate locking mechanisms and gates, reducing manufacturing costs.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The locking device is designed to be self-actuating through the clamping device's movement. When the clamping jaws close, they automatically lock the safety device without requiring additional gates or manual intervention. The system uses its own operational movement to perform the locking function, eliminating the need for separate actuating mechanisms.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If the locking device is decoupled from the clamping device operation, then the safety device can be locked at any time, but the operational complexity and cost increase

Engineering Contradiction:
Improvelocking operation flexibilityVSAvoidlocking mechanism complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The locking device is coupled with the clamping device through the locking lever, which is actuated by the clamping jaws' movement. This integration ensures that locking operations occur automatically at the appropriate times during the clamping cycle, simplifying the overall system while maintaining operational flexibility.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The locking device is designed to lock the safety device in advance during the clamping operation. The locking lever is positioned and actuated as part of the clamping sequence, ensuring the safety device is locked before the transportation device moves, and unlocked when the clamping jaws open at the station.

Inventive Principle:
Principle #10Preliminary action
