Movable Cable Spooling Cart With Lightweight Rigid Base Plate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing movable cable spooling apparatuses are bulky and not suited for manual handling without ancillary tracking means, necessitating a lightweight and cost-effective design that allows for manual operation.
Innovation Solution
A frame with a rigid base plate supports the drum and cable guide, equipped with wheels, a handlebar, and an anchoring organ, along with a compact design and pulley system to facilitate manual handling and stability, while a motor-driven drum enhances functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a traditional single axle trailer frame is used to support the drum, then the apparatus can support cable winding operations, but the apparatus becomes bulky and unsuitable for manual handling
Solution Approach 1:
The frame is segmented into a rigid base plate for structural support and separate functional components (drum, cable guide, anchoring organ) that can be optimally positioned. This segmentation allows the base plate to be thin and lightweight while maintaining overall structural stability through strategic component placement and the triangulation effect of the anchoring organ positioning.
2Weight of moving object
If the base plate is made thin and lightweight to facilitate manual handling, then the apparatus becomes easier to move, but the structural stability may be compromised under cable load
Solution Approach 1:
The base plate is designed with local quality optimization - it is thin and lightweight overall but strategically reinforced at critical stress points where the drum and cable guide are mounted. The anchoring organ positioning creates a triangulated support structure that distributes loads efficiently across the base plate, allowing minimal material usage while maintaining stability.
Solution Approach 2:
The anchoring organ is positioned in advance on the base plate to create a predetermined stable triangulation geometry. This preliminary positioning ensures that when the apparatus is suspended or loaded, the forces are automatically distributed along optimal paths, preventing stress concentration on the thin base plate.
3Ease of operation
If the cable runs far from the base plate to accommodate drum rotation, then the drum can operate freely, but the apparatus becomes bulkier and harder to handle manually
Solution Approach 1:
The cable path is routed through the third dimension by passing under the base plate between the drum and cable guide. This vertical dimension utilization allows the cable to clear the drum rotation path while keeping the horizontal footprint minimal, maintaining apparatus compactness for manual handling while preserving full drum operational freedom.
