Solution Overview

Problem

Existing tool carts used for transporting tools from delivery vans to work locations are prone to accidents during loading and unloading due to their weight, which can be hazardous for a single person to handle safely.

Innovation Solution

A docking mechanism with a transport undercarriage that can only be transferred from a position of use to a docking position when in a blocking mode, featuring a blocking actuator and coupling assembly to prevent the transport means from falling, allowing for safe loading and unloading without lifting, and a receiving assembly with an engaging member to compensate for height differences.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If a tool cart is made heavy to carry sufficient tools, then the carrying capacity is improved, but the safety during loading and unloading deteriorates

Engineering Contradiction:
Improvecarrying capacityVSAvoidsafety during loading and unloading
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The patent introduces a vehicle as an intermediary carrier between the tool cart and the final destination. The docking mechanism enables the tool cart to be securely coupled to and decoupled from the vehicle, transferring the safety burden from manual handling to the vehicle-based system with blocking mechanisms.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The blocking mechanism is activated before the tool cart is fully loaded or unloaded. The blocking member prevents the tool cart from moving off the vehicle prematurely, ensuring that coupling and uncoupling operations are performed safely before weight changes occur.

Inventive Principle:
Principle #10Preliminary action

2Quantity of substance

If a tool cart is made heavy to carry sufficient tools, then the carrying capacity is improved, but the ease of operation deteriorates

Engineering Contradiction:
Improvecarrying capacityVSAvoidease of handling
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The vehicle serves as an intermediary that handles the heavy tool cart during transport. The docking mechanism with coupling and blocking members enables easy attachment and detachment operations, transferring the heavy lifting task from manual effort to the vehicle-based system.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system separates the tool cart from the vehicle, allowing the tool cart to be a lightweight, maneuverable unit that can be easily coupled and uncoupled. The heavy carrying capacity is achieved through the combined system rather than the cart alone.

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If the transport means is lifted during docking, then the loading and unloading is facilitated, but the complexity of the docking mechanism increases

Engineering Contradiction:
Improveease of loading and unloadingVSAvoiddocking mechanism complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The docking mechanism operates at a constant height without lifting or lowering the transport means. The blocking member and coupling assembly are designed to function at the same vertical level, eliminating the need for height adjustment mechanisms while maintaining ease of operation.

Inventive Principle:
Principle #12Equipotentiality

4Ease of operation

If the transport means is allowed to move freely during docking, then the ease of positioning is improved, but the safety deteriorates

Engineering Contradiction:
Improveease of positioningVSAvoidsafety during docking
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The blocking member is engaged before the transport means is fully positioned on the vehicle. This preliminary blocking action prevents accidental movement or falling during the docking operation, ensuring safety while maintaining ease of positioning.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The blocking member acts as an intermediary safety mechanism between the transport means and the vehicle. It provides a mechanical constraint that prevents unsafe movement while allowing the operator to position the transport means easily.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

The present invention relates to a docking mechanism for docking a dockable transport means, comprising at least a transport undercarriage with transport means such as wheels, in safeguarded manner to a receiving location, such as a receiving location which can be arranged on a vehicle, such as a road, marine or airborne vehicle, wherein the transport undercarriage can only be transferred from a position of use to a docking position when the transport means is situated in a blocking mode relative to the receiving location, and wherein the blocking mode can be discontinued only when the transport undercarriage is situated in the position of use.
