Solution Overview

Problem

Existing personnel lifts face challenges in ensuring safety during the transport of objects, as they may collide with obstacles due to inadequate path visibility or unforeseen obstructions, leading to potential damage or accidents.

Innovation Solution

A loading system for freight elevators that includes a platform with detection means to identify lateral mechanical stresses, triggering a stop mechanism when obstacles are detected, ensuring safety by preventing collisions and allowing for easy conversion between seat and platform configurations without requiring tools.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a remote control is used to command the basket to complete the entire journey automatically, then the operator's hands are freed for other tasks, but the basket may hit obstacles that the operator cannot see

Engineering Contradiction:
Improveoperator convenienceVSAvoidsafety during transport
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The detection means (sensors, cameras, or other detection devices) are mounted on the basket to enable it to autonomously detect obstacles in its path. The basket essentially monitors its own environment and can trigger automatic stopping without continuous operator attention, allowing the operator to use remote control for other tasks while maintaining safety

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The detection means provide real-time feedback about obstacles to the control system. When an obstacle is detected, the system receives feedback and automatically stops the basket, creating a closed-loop control system that enhances safety during automated operation

Inventive Principle:
Principle #23Feedback

2Reliability

If the platform is permanently installed on the cradle, then safety during object transport is ensured, but the ability to quickly convert between seat and platform configurations is reduced

Engineering Contradiction:
Improvesafety during object transportVSAvoidconversion between seat and platform
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The platform is designed with dynamic fixing means that can be quickly engaged and disengaged from the cradle. This allows the platform to transition between a fixed state (when transporting objects for enhanced safety) and a removable state (when seat configuration is needed), providing both safety during transport and operational flexibility

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The fixing means are designed to be universal, allowing the same mechanism to securely attach both the platform and the seat to the cradle. This multi-functional attachment system ensures that either configuration can be quickly installed and removed without requiring different fixing mechanisms, maintaining both safety and adaptability

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

3Reliability

If detection means are added to detect obstacles, then safety is improved, but the device complexity increases

Engineering Contradiction:
Improvesafety during transportVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The detection function is extracted as a separate, modular component that can be independently added to or removed from the basket. This allows the core safety function to be enhanced without fundamentally redesigning the entire lift system, and the detection means can be selectively installed based on specific operational needs

Inventive Principle:
Principle #2Taking out (Extraction)
