Solution Overview
Problem
Conventional soil compaction devices and vibrating plate compactors are heavy, voluminous, and require high electrical power, leading to incompatible power supply systems with power tools, limiting weight distribution optimization and compaction efficiency on construction sites.
Innovation Solution
A vibrating plate compactor with a fast-rotating electric motor operating at over 12,000 rpm, a compact drive unit design with the motor and power supply arranged in a lower region, and a spur gearing system, allowing for a lightweight, compact, and efficient compaction device with improved weight distribution and handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If conventional motors with 3,000-6,000 rpm are used to drive the base plate, then sufficient vibration power is achieved, but the motor size, weight, and volume increase significantly
Solution Approach 1:
The patent changes the rotational speed parameter of the motor from conventional 3,000-6,000 rpm to high-speed 12,000-20,000 rpm. This parameter change allows achieving the required vibration power with a smaller, lighter motor, directly resolving the contradiction between power output and motor weight
2Power
If high power motors are used to vibrate the base plate, then compaction effectiveness is improved, but the drive unit becomes large and voluminous
Solution Approach 1:
By increasing the motor speed parameter to 12,000-20,000 rpm, the patent achieves high power output in a compact form factor. The high-speed motor requires less torque, allowing for a smaller drive unit volume while maintaining the necessary 1,000-3,000 watts power level for effective compaction
3Power
If large capacity power supply devices are used to meet the 1,000-3,000 watts power demand, then sufficient electrical power is provided, but compatibility with standard power tools is lost
Solution Approach 1:
The patent designs the power supply system to be universal by accepting standard rechargeable battery packs (18V, 36V, 54V) that are commonly used across various power tools. This multi-functionality allows the same battery platform to serve both power tools and the vibrating plate compactor, resolving the contradiction between power delivery and compatibility
4Weight of moving object
If the motor and power supply are arranged in the lower region, then weight distribution is optimized for compaction, but accessibility for maintenance becomes more difficult
Solution Approach 1:
The patent employs a modular drive unit design where the motor and power supply can be dynamically accessed through removable panels or quick-release mechanisms. This allows the components to remain in the optimal lower position for weight distribution while providing easy accessibility for maintenance and repair operations
