Solution Overview

Problem

The arrangement of batteries in existing handling machines, particularly in small-sized machines, negatively impacts their compactness and lateral balance.

Innovation Solution

Positioning first and second electrical energy storage units on either side of the lifting arm, with the first unit rear of the cab and the second unit opposite in a transverse direction, balances mass distribution and maintains lateral balance while preserving accessibility and protecting against impacts.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If the battery is placed behind the chassis, then the compactness of the handling machine is improved, but the lateral balance of the machine is worsened

Engineering Contradiction:

ImprovecompactnessVSAvoidlateral balance

Core Design Contradiction:

Volume of moving objectVSStability of the object's composition

Solution Approach 1:

The battery system is divided into two separate electrical energy storage units positioned on opposite sides of the lifting arm. This segmentation allows the mass to be distributed laterally rather than concentrated at the rear, thereby maintaining compactness while achieving lateral balance through symmetric placement.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent employs asymmetric positioning relative to the chassis centerline but symmetric positioning relative to the lifting arm axis. The batteries are placed on either side of the lifting arm at positions that create lateral balance, transforming the asymmetric constraint into a balanced configuration that satisfies both compactness and stability requirements.

Inventive Principle:

Principle #4Asymmetry

2Ease of operation

If the battery is positioned at the rear of the vehicle, then accessibility is improved, but the risk of impacts during use is increased

Engineering Contradiction:

ImproveaccessibilityVSAvoidrisk of impacts

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The battery units are positioned in the lateral dimension (on either side of the lifting arm) rather than only in the longitudinal dimension (at the rear). This dimensional shift allows the batteries to be accessible from the side while being elevated and positioned away from ground-level impact zones, thereby reducing impact risk while maintaining accessibility.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)
