Concrete Vibrator Cart and Cable Drum for Easier Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Concrete vibrators are heavy and require frequent lifting, making them cumbersome to move around construction sites.
Innovation Solution
A concrete vibrator system comprising a vibrating head, power box, and storage cart with a frame, cable, and drum, allowing for easy transport and storage of the vibrator by offsetting the center of mass and using a rotatable shaft with a motor, along with a cable system for power transmission and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the concrete vibrator is made heavy-duty for construction operations, then the vibration power and motor strength are improved, but the weight increases making it difficult to move
Solution Approach 1:
The concrete vibrator is divided into separate components: a head assembly containing the motor and shaft, a power box with battery pack, and a storage cart. This segmentation allows the heavy components to be distributed and transported separately, reducing the burden during movement while maintaining full functionality when assembled.
Solution Approach 2:
A storage cart serves as an intermediary device to transport both the head assembly and power box. The cart includes a drum for cable storage and provides a platform for moving the heavy vibrator components without requiring manual lifting, thus resolving the contradiction between power and portability.
2Adaptability or versatility
If the cable length is increased to extend working range, then the operational flexibility is improved, but the cable management and storage becomes more difficult
Solution Approach 1:
The cable is wound and stored on a drum integrated into the storage cart. This nesting arrangement allows the long cable to be compactly stored within the drum structure, preventing tangling and making cable management simple while maintaining the ability to extend the cable to various lengths for operational flexibility.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates easy and efficient movement of the concrete vibrator between sites, reducing user effort and improving operational efficiency in construction operations.
Implementation Method 1
The motor is configured to provide torque to cause the shaft to rotate
Implementation Method 2
The drum is supported by the frame, and the second cable is selectively wrapped around and selectively extendible from the drum
Implementation Method 3
The wheel is rotatably coupled to the frame to facilitate transport of the storage cart along a surface

AI summary
A concrete vibrator system comprising a vibrating head, a power box, a first cable, and a storage cart. The vibrating head includes a shaft and a motor. The shaft has a center of mass radially offset from a rotational axis of the shaft. The first cable is coupled to vibrating head at a first end thereof. The first cable is configured to transmit electrical current to the motor. The first cable has a first length extending from the vibrating head to an opposite, second end of the first cable. The storage cart includes a frame, a second cable, and a drum. The second cable is connectable to the first cable and the power box. The second cable has a second length greater than the first length. The drum is supported by the frame, and the second cable is selectively wrapped around and selectively extendible from the drum.
