Solution Overview

Problem

Existing methods for mounting a forklift onto a carrying vehicle require operators to work at elevated heights, posing safety risks and requiring significant skill, as they need to manually position the forklift while it is raised or lowered.

Innovation Solution

A method using a top mount system with a track and carriage, operated by a remote control unit, allows the forklift to be raised and positioned onto the vehicle bed without the operator needing to be at height, utilizing a hydraulic ram to move the carriage along the track and a lifting assembly to adjust the forks, enabling remote operation of the forklift's lifting and drive units.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the operator manually positions the forklift while it is raised or lowered, then the forklift can be mounted onto the carrying vehicle, but the operator is exposed to height-related hazards and requires significant skill

Engineering Contradiction:
Improveease of mounting forkliftVSAvoidheight-related hazards
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

A remote control unit acts as an intermediary device, allowing the operator to control the forklift's lifting and positioning from a safe distance on the ground. The remote control unit transmits control signals to the lifting assembly and drive units, eliminating the need for the operator to be at height while maintaining full control over the mounting process.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The manual mechanical positioning system is replaced with an automated hydraulic lifting system controlled remotely. The hydraulic ram and lifting assembly automatically raise and lower the forklift based on remote control signals, substituting manual mechanical operations with an automated system that reduces operator exposure to hazards.

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

2Ease of operation

If the operator manually positions the forklift while it is raised or lowered, then the forklift can be mounted onto the carrying vehicle, but the operator requires significant skill for operation

Engineering Contradiction:
Improveease of mounting forkliftVSAvoidskill requirement
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The remote control unit serves as an intermediary that simplifies the operation interface. Instead of requiring the operator to manually manipulate complex mechanical controls at height, the remote control unit provides simplified control mechanisms that can be operated from the ground, reducing the skill threshold while maintaining precise control over the mounting process.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If the forklift is raised up onto the bed of the carrying vehicle, then the forklift can be securely mounted, but the operator must work at significant height posing safety risks

Engineering Contradiction:
Improvesecurity of forklift mountingVSAvoidsafety risks at height
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The remote control unit acts as a mediator that enables secure mounting while maintaining operator safety. It transmits control signals to the hydraulic lifting assembly, allowing the forklift to be raised and secured on the carrying vehicle bed without the operator needing to be present at height, thus eliminating safety risks while maintaining mounting reliability.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The manual mechanical lifting system is replaced with an automated hydraulic system controlled remotely. The hydraulic ram automatically performs the lifting and securing operations based on remote control signals, substituting manual mechanical operations with an automated system that ensures reliable mounting while keeping the operator safe on the ground.

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

AI summary

This invention relates to a top mount method, a top mount system (41) and a combination of forklift truck (1) and carrying vehicle (5) having such a top mount system. The top mount method differs from the known methods in that the forklift truck lifting assembly (11) at least is provided with a remote control unit (33) to permit the operator of the forklift to mount the forklift onto the carrying vehicle (5) from a position remote from the forklift. The top mount system (41) comprises a track (7) having a carriage (9) slidably mounted therein and a ram (49) for moving the carriage relative the track. This obviates the need to use the drive of the forklift under remote operation. Finally, there is provided a combination of a forklift and a carrying vehicle having the top mount system which together provide a useful and safer alternative to the known combinations.
