Solution Overview

Problem

Existing automated container handling systems face issues with the short lifespan and increased size of catenary cable holders, leading to inefficiencies in space optimization and reduced cycle life, particularly when handling smaller containers.

Innovation Solution

The system incorporates a telescopic fork with energy accumulating means, such as a capacitor battery, and a wireless connecting module for the actuators, allowing for reduced overall size and extended cycle life, while optimizing space usage by eliminating the need for traditional catenary cable holders.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a catenary cable holder is used to electrically supply actuators, then the actuators can be powered, but the cable holder has a short lifespan (maximum 100,000 cycles) compared to the telescopic system (about 3 million cycles)

Engineering Contradiction:
Improvelifespan of electrical supply systemVSAvoidcycle life of catenary cable holder
Core Design Contradiction:
ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The patent extracts and eliminates the catenary cable holder from the system by using a wireless power transmission mechanism. The actuators are powered wirelessly through electromagnetic induction, removing the mechanical cable holder that limited the system to 100,000 cycles and allowing the telescopic system to achieve its full 3 million cycle potential.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces the mechanical catenary cable holder system with an electromagnetic wireless power transmission system. This substitution eliminates the mechanical wear and fatigue issues of the cable holder while maintaining reliable electrical supply to the actuators throughout the extended operational life of the telescopic system.

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

2Use of energy by moving object

If a catenary cable holder is used to electrically supply actuators, then the actuators can be powered, but the holder increases the vertical lateral overall sizes and encumbrance of the telescopic system

Engineering Contradiction:
Improveelectrical supply to actuatorsVSAvoidvertical lateral overall sizes
Core Design Contradiction:
Use of energy by moving objectVSVolume of moving object

Solution Approach 1:

The patent removes the catenary cable holder entirely from the system architecture. By implementing wireless power transmission through electromagnetic fields, the system eliminates the physical cable holder that added vertical lateral dimensions, thereby reducing the overall volume and encumbrance of the telescopic system.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent transitions from a three-dimensional mechanical cable holder occupying vertical lateral space to an electromagnetic field-based power transmission that operates in the electromagnetic dimension. This dimensional shift allows power supply without physical encumbrance, reducing the system's spatial footprint.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Use of energy by moving object

If a catenary cable holder is used, then electrical supply is provided, but the increased encumbrance prevents optimization of automatic warehouse sizes for smaller containers

Engineering Contradiction:
Improvepower supply capabilityVSAvoidadaptability to containers of various sizes
Core Design Contradiction:
Use of energy by moving objectVSAdaptability or versatility

Solution Approach 1:

By extracting and removing the catenary cable holder, the patent enables the telescopic system to achieve its minimum possible dimensions. This elimination of excess volume allows the system to adapt to and efficiently handle smaller containers, improving versatility across different container sizes while maintaining full power supply capability through wireless transmission.

Inventive Principle:
Principle #2Taking out (Extraction)

4Use of energy by moving object

If the encumbrance of the catenary cable holder is included, then electrical supply is ensured, but the minimum shelf height increases to about 200 mm, causing space waste for smaller boxes

Engineering Contradiction:
Improveelectrical power to actuatorsVSAvoidminimum shelf height
Core Design Contradiction:
Use of energy by moving objectVSLength of stationary object

Solution Approach 1:

The patent extracts and eliminates the catenary cable holder that imposed the 200 mm minimum shelf height constraint. By replacing it with wireless power transmission, the system reduces its vertical footprint, allowing shelves to be positioned at optimal heights for smaller containers and eliminating the 20 mm space waste per shelf.

Inventive Principle:
Principle #2Taking out (Extraction)
