Forklift Charging Cable Holder Integrated Into Wall Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing forklift trucks with battery-electric drive systems face challenges in carrying charging cables efficiently, requiring additional construction effort and cumbersome handling due to storage containers in the counterweight, which complicate access and usage.
Innovation Solution
A wall element is designed as a holder for the charging cable, allowing it to be detachably attached, eliminating the need for additional storage containers and enabling easy handling by integrating a storage recess and flexible retaining clips for secure attachment of both ends of the cable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a storage container is arranged in the counterweight to carry the charging cable, then the charging cable can be stored, but additional construction effort and space requirements within the counterweight are required
Solution Approach 1:
The patent merges the charging cable storage function with the existing counterweight structure by providing a storage compartment within the counterweight that is integrated into its design. This eliminates the need for separate additional storage containers while maintaining cable storage capability.
Solution Approach 2:
The counterweight is designed to serve multiple functions: maintaining vehicle balance and providing integrated storage for the charging cable. The storage compartment is formed as part of the counterweight structure, allowing the same component to fulfill both its traditional function and cable storage without requiring separate dedicated space.
2Quantity of substance
If a storage container in the counterweight is used to carry the charging cable, then the cable can be stored, but handling becomes cumbersome and time-consuming since the counterweight cover must be opened and the storage container opened to access the cable
Solution Approach 1:
The patent extracts the charging cable from deep within the counterweight structure and provides direct access to it. The storage compartment is designed with an opening that allows the cable to be accessed without opening the counterweight cover, separating the cable access function from the counterweight cover operation.
Solution Approach 2:
The charging cable is positioned in the storage compartment such that it is readily accessible and can be quickly removed when needed. The compartment design allows the cable to be pulled out directly without requiring preliminary steps of opening covers or lids, enabling immediate access for charging operations.
3Quantity of substance
If additional storage containers are provided in the counterweight, then charging cable storage is enabled, but space requirements within the counterweight increase
Solution Approach 1:
The storage compartment for the charging cable is nested within the counterweight structure itself. The compartment utilizes the internal volume of the counterweight, nesting the storage function within the existing structural component rather than adding external or separate storage elements.
Solution Approach 2:
The storage compartment is merged with the counterweight structure, forming an integrated unit. The compartment walls are formed by the counterweight structure itself, combining the storage function with the existing component and eliminating the need for additional space-consuming separate storage containers.
