A-Frame Wire Pull Cart Structure for Stable Spool Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional pull carts are inadequate for transporting heavy wires, lacking stability, capacity, maneuverability, and compatibility, leading to issues such as wire falling off, difficulty in maneuvering through tight spaces, and inadequate support for the wires and people transporting them.
Innovation Solution
An A-frame pull cart design featuring two A-frame trusses and a base portion with wheels, which provides stability and maneuverability by evenly distributing the weight of heavy spools across multiple wheels, allowing spools to rotate and includes a shelf for additional weight to prevent tipping, and incorporates a spool crossbar for secure wire storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional pull carts are used to transport heavy wires, then the cart structure is simple, but the cart lacks stability and wires may fall off during transport
Solution Approach 1:
The cart is divided into distinct functional components: an A-frame support structure with crossmembers for wire storage, a separate base portion with wheels for mobility, and a shelf portion for additional support. This segmentation allows each component to be optimized for its specific function while maintaining overall stability.
Solution Approach 2:
The A-frame support structure uses asymmetric geometry with crossmembers positioned at specific angles and heights to create a stable triangular configuration. This asymmetric design provides inherent structural stability and prevents the cart from tipping during wire transport.
2Quantity of substance
If traditional pull carts are used to carry heavy wires, then the cart is easy to manufacture, but the cart lacks capacity to hold thick or heavy lengths of wire
Solution Approach 1:
The cart utilizes vertical space through the A-frame structure with crossmembers extending at different heights, creating multiple storage levels. This dimensional approach allows the cart to hold longer and heavier wire lengths by distributing them across multiple crossmembers rather than requiring a larger horizontal footprint.
3Ease of operation
If traditional pull carts are loaded with lengths of wire, then the cart can transport wire, but the cart is difficult to maneuver through tight spaces
Solution Approach 1:
The shelf portion positioned at the rear of the cart acts as a counterweight to balance the weight of wire stored on the A-frame crossmembers. This counterbalancing design reduces the overall center of gravity and makes the cart easier to maneuver through tight spaces even when loaded with heavy wire.
4Object-affected harmful factors
If traditional pull carts are used for wire transport, then the cart design is simple, but the cart provides inadequate support and protection for the wire and people transporting it
Solution Approach 1:
The cart is designed with multi-functional components: the A-frame crossmembers serve both as structural support and wire storage; the shelf portion provides both additional wire capacity and counterbalancing; the base portion with wheels provides both mobility and stability. This universality allows the cart to protect wire and support operators without requiring separate specialized components.

AI summary
Pull carts configured for holding, transporting, and storing spools of wire or cable. A cart includes an A-frame truss comprising a plurality of crosswise beams, wherein the plurality of crosswise beams comprises: a proximal end attached to a cart base, and a distal end opposite the proximal end, wherein the distal end forms an apex of the A-frame truss. The cart includes a rod support configured to receive a spool crossbar, wherein the rod support is disposed at the apex of the A-frame truss.
