Solution Overview

Problem

Existing cable car systems lack flexibility in controlling the opening and closing of doors within a cable car station, as these operations are typically tied to specific scenery control sequences, limiting adaptability in emergency situations or system malfunctions.

Innovation Solution

Implementing a remote control system that allows the actuation device on the cable car vehicle to open and/or close the access barrier independently of mechanical obsessive-compulsive control, using a remote control unit that can be stationary or portable, such as a mobile phone or portable computer.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a mechanical positive control system with guide rail is used to control access barrier operation, then the door control is reliable and stable, but the flexibility and adaptability of door opening/closing positions and times are limited

Engineering Contradiction:
Improvedoor control reliabilityVSAvoiddoor control flexibility
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent applies dynamics by making the access barrier control system adjustable and adaptable. The barrier can be opened and closed at variable positions and times within the cable car station, transforming a static fixed-position system into a dynamic flexible system that can adapt to different operational requirements and emergency situations.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The invention changes the control parameters of the access barrier system. Instead of fixed position and time parameters determined by guide rail geometry, the system allows variable position and time parameters to be set, enabling flexible control of when and where the barrier opens and closes within the station.

Inventive Principle:
Principle #35Parameter changes

2Stability of the object's composition

If guide rail system is used for door control, then the control sequence is fixed and stable, but changing opening and closing positions requires changing the fixed guide rail system which is complex and difficult

Engineering Contradiction:
Improvecontrol sequence stabilityVSAvoidsystem modification ease
Core Design Contradiction:
Stability of the object's compositionVSEase of manufacture

Solution Approach 1:

The patent segments the control system into independent controllable units. Instead of a monolithic guide rail system where changing one position requires modifying the entire rail structure, the control is divided into separate actuation points that can be independently adjusted, making the system easier to modify and adapt.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention replaces the purely mechanical guide rail control system with a hybrid system that incorporates remote control capabilities. This substitution allows electronic or wireless control methods to override or supplement the mechanical guide rail system, enabling flexible position changes without physical rail modifications.

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

3Reliability

If manual intervention is required to open doors in emergency situations, then skilled operators can handle emergencies, but the response time is delayed and significant effort is required

Engineering Contradiction:
Improveemergency handling capabilityVSAvoidemergency response time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent implements preliminary action by providing a pre-configured remote control system that is ready for immediate use in emergency situations. The actuating device is pre-installed and can be activated remotely without requiring manual intervention, ensuring rapid response to emergencies before they escalate.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The invention introduces an intermediary remote control system between the operator and the access barrier. This intermediary allows control signals to be transmitted remotely to actuate the barrier, eliminating the need for direct manual intervention and significantly reducing emergency response time and physical effort required.

Inventive Principle:
Principle #24Intermediary (Mediator)
