Solution Overview

Problem

Current aerial cable transport systems face high electricity consumption for heating transport units, leading to environmental pollution and increased operating costs due to the continuous supply of heating elements without passenger occupancy detection.

Innovation Solution

A heating system with a recognition device to detect passenger presence, a power supply circuit with a switch assembly, and a control unit to selectively activate heating elements only when passengers are present, reducing energy waste by controlling the power supply of electrically conductive elements along the transport path.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If heating elements are continuously supplied with electricity to ensure passenger comfort, then the comfort of passengers is improved, but electricity consumption and environmental pollution increase

Engineering Contradiction:
Improvepassenger comfortVSAvoidelectricity consumption
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

The heating system transitions from continuous operation to dynamic, demand-based operation. The control unit activates heating elements only when transport units are detected in the heating section, creating a flexible system that adapts to actual operational needs rather than running continuously

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system implements feedback control through proximity sensors that detect the presence of transport units in the heating section. This information is fed to the control unit, which then activates or deactivates the heating elements accordingly, creating a closed-loop system that responds to real-time conditions

Inventive Principle:
Principle #23Feedback

Solution Approach 3:

The heating system becomes self-regulating through the automated detection and control mechanism. The system automatically activates heating when needed and deactivates it when transport units are absent, eliminating the need for continuous manual monitoring or oversight

Inventive Principle:
Principle #25Self-service

2Ease of operation

If heating elements are activated continuously to maintain temperature, then passenger comfort is ensured, but operating costs increase

Engineering Contradiction:
Improvepassenger comfortVSAvoidoperating costs
Core Design Contradiction:
Ease of operationVSLoss of energy

Solution Approach 1:

The heating system operates periodically rather than continuously. The control unit activates heating elements in periodic intervals when transport units are detected, and deactivates them when units are absent, creating a rhythmic on-off pattern that reduces overall energy consumption while maintaining comfort when needed

Inventive Principle:
Principle #19Periodic action

3Device complexity

If heating elements are supplied without passenger detection, then system simplicity is maintained, but energy waste increases

Engineering Contradiction:
Improvesystem simplicityVSAvoidenergy waste
Core Design Contradiction:
Device complexityVSLoss of energy

Solution Approach 1:

The patent introduces intermediary components (proximity sensors and a control unit) that mediate between the heating elements and the power supply. These intermediaries detect transport unit presence and control the activation of heating elements, adding minimal complexity while eliminating significant energy waste

Inventive Principle:
Principle #24Intermediary (Mediator)
