Solution Overview

Problem

Existing devices for storing and managing transportation equipment in cable car systems are inefficient due to limited storage rail length and high technical complexity, leading to increased maintenance and operational costs.

Innovation Solution

A motor-driven carriage system that moves along the storage rail, utilizing a ballast body for static friction and an electric motor for propulsion, allowing for efficient storage and retrieval of equipment without additional technical effort, and enabling longer storage rails with a single vehicle.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If pivotable storage rails are used to enable gravity-based movement of equipment, then equipment can be moved automatically along the rail, but the storage rail length is limited and more rails are required increasing technical outlay

Engineering Contradiction:
Improveautomatic equipment movementVSAvoidnumber of storage rails
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The storage system is divided into multiple storage rails (first storage rail, second storage rail) that can be independently operated. Each rail can be pivoted separately to control equipment movement, allowing the system to manage equipment in segments rather than requiring a single long complex rail.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The storage rails are designed to be pivotable about a horizontal axis, allowing dynamic adjustment between inclined and horizontal positions. This enables the rails to adapt their configuration based on operational needs, facilitating equipment movement without requiring fixed rigid structures.

Inventive Principle:
Principle #15Dynamics

2Productivity

If chain conveyors or roller conveyors extending along the entire storage rail are used, then equipment can be transported throughout the storage area, but the structural complexity and installation/maintenance costs increase

Engineering Contradiction:
Improveequipment transport capabilityVSAvoidconveyor system structure
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The complex conveyor system is extracted and replaced by utilizing the existing conveyor device at the entrance of the storage area. Equipment is transferred to storage rails and moved within storage primarily through gravity and manual intervention, removing the need for extensive conveyor infrastructure along the entire storage rail length.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The system uses gravity-based movement where equipment naturally rolls or slides along the inclined storage rails without requiring powered conveyors. The horizontal positioning and retrieval operations are performed manually or with simple mechanical assistance, allowing the system to serve itself without complex automated conveyor mechanisms.

Inventive Principle:
Principle #25Self-service

3Device complexity

If a single vehicle pushes all equipment back to the conveyor device, then fewer vehicles are needed, but sufficient driving force must be generated for long storage rails

Engineering Contradiction:
Improvenumber of vehiclesVSAvoiddriving force
Core Design Contradiction:
Device complexityVSForce

Solution Approach 1:

A ballast body is added to the vehicle to increase its weight and consequently the static friction between the drive wheels and the storage rail. This counteracts the reduced driving force issue by creating sufficient friction grip to push equipment along long storage rails without requiring multiple vehicles.

Inventive Principle:
Principle #8Anti-weight (Counterweight)

Solution Approach 2:

The vehicle's weight parameter is changed by adding a ballast body, which directly affects the friction coefficient between the drive wheels and rail. This parameter modification enables the single vehicle to generate sufficient driving force for extended storage rail configurations.

Inventive Principle:
Principle #35Parameter changes
