Solution Overview

Problem

Existing forklift truck battery arrangements are not flexible enough to accommodate different sizes and load lifting heights, affecting the center of gravity and stability, especially when using battery elements of varying weights.

Innovation Solution

A holding device with compartments that allow horizontal placement of battery elements and weights, maintaining the center of gravity's horizontal position, enabling easy adaptation to different load sizes and lifting heights, and incorporating transport means for safe handling and secure fastening.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If battery elements are arranged vertically in the holding device, then the forklift truck can accommodate different battery configurations, but the center of gravity shifts horizontally in the transversal direction, affecting stability and turning properties

Engineering Contradiction:
Improvebattery configuration flexibilityVSAvoidcenter of gravity position
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The holding device is designed with asymmetric compartment arrangement where compartments are positioned to receive battery elements in a horizontal arrangement. This asymmetric design ensures that the weight of the battery element is applied on the centre of a longitudinal symmetry axis of the forklift truck, preventing horizontal shift of the center of gravity in the transversal direction while maintaining configuration flexibility.

Inventive Principle:
Principle #4Asymmetry

Solution Approach 2:

The patent transitions from traditional vertical battery arrangement to horizontal arrangement within the holding device compartments. This dimensional change allows battery elements to be placed horizontally rather than vertically, enabling the weight to be centered on the longitudinal symmetry axis and maintaining center of gravity stability while accommodating different battery configurations.

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

2Adaptability or versatility

If battery elements of varying weights are used, then the forklift truck can be adapted to different load sizes, but the horizontal position of the center of gravity changes, affecting stability

Engineering Contradiction:
Improveload size adaptationVSAvoidcenter of gravity horizontal position
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The holding device employs asymmetric compartment positioning that aligns with the longitudinal symmetry axis of the forklift truck. This asymmetric arrangement ensures that regardless of the battery element weight, the weight is always applied on the centre of the longitudinal symmetry axis, preventing horizontal shift of the center of gravity in the transversal direction while allowing adaptation to different load sizes.

Inventive Principle:
Principle #4Asymmetry

3Stability of the object's composition

If the holding device allows vertical support on the ground, then the forklift truck can be stabilized, but the flexibility to adapt to different lifting heights is reduced

Engineering Contradiction:
Improvevertical support stabilityVSAvoidlifting height adaptation
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The holding device is designed with universal compartments that can accommodate both battery elements and weights in horizontal arrangements. This multi-functional design allows the same holding device structure to serve multiple purposes: providing stability through horizontal battery placement and enabling adaptation to different lifting heights through weight accommodation, without requiring separate mechanisms for each function.

Inventive Principle:
Principle #6Universality (Multi-functionality)
