Handcart Movable Platform for Heavy Load Alignment

Solution Overview

Problem

Conventional handcarts struggle to align heavy loads, such as batteries, with vehicle mounting sections due to the difficulty in maneuvering the handcart while handling the weight.

Innovation Solution

A handcart with a movable platform on its upper surface, allowing lateral movement, and an omni-directional wheel system at the rear, enabling easy adjustment and alignment of loads without requiring manual steering of the handcart.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the handcart is operated by moving the entire cart to align the load with the mounting section, then the alignment can be achieved, but it becomes very difficult when the load is heavy (several hundred kilograms)

Engineering Contradiction:

Improveease of alignmentVSAvoidweight of load

Core Design Contradiction:

Ease of operationVSWeight of moving object

Solution Approach 1:

The handcart is divided into a fixed vehicle main body and a movable platform that can be independently positioned. The platform can move laterally relative to the vehicle main body, allowing the load on the platform to be aligned with the mounting section without moving the entire heavy cart. This segmentation enables independent positioning of the load-carrying portion.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The platform is designed with dynamic movement capability in the lateral direction, transitioning from a static fixed position to a movable position. This dynamic feature allows the platform to be adjusted laterally to align the load with the mounting section while the vehicle main body remains stationary, making operation feasible even with heavy loads.
