The weight optimization of the entire machine is the first breakthrough. The weight of traditional gasoline flat vibrators ranges from 70 to 90 kg. I reduced the weight to 55 kg through four weight reduction designs: the engine uses an aluminum cylinder block, which is 35% lighter than cast iron; the frame uses high-strength steel tubes, with the wall thickness reduced from 3 mm to 2.5 mm while maintaining the same strength; the base plate adopts a honeycomb structure design, reducing the weight by 20% while maintaining 95% rigidity; all non-load-bearing components use engineering plastics. During actual testing, my equipment was easily lifted and moved by two people, while traditional equipment required three people.
The balance of operating torque reduces physical exertion. I calculated ergonomic data and designed the operating handle height to be adjustable within the range of 850-1050 mm, suitable for operators of different heights. The handle angle I set is 15 degrees forward tilt, in line with the natural grip posture of the human body. The steering system I optimized the transmission ratio, with the full-load steering torque not exceeding 35 N·m, 45% lower than the traditional design. In the Barcelona test, after female operators worked continuously for 2 hours, the arm fatigue was only 40% of that of the traditional equipment.
The innovation of the starting system simplifies the operation process. The traditional recoil starting requires forceful and rapid pulling. I designed a助力 starting system： an internal torsion spring provides auxiliary assistance when pulling； the compression ratio was optimized， reducing the starting resistance by 30%； the starting handle conforms to the hand shape， with a grip diameter of 32 mm and a surface anti-slip design. During actual testing， the starting pull force of my equipment was no more than 150 N, and female operators could easily start it.
The optimization of walking control improves operational accuracy. I developed a stepless speed regulation walking system, with the speed smoothly adjustable within the range of 0-20 m/min. The speed control handle I arranged is within the natural movement range of the right thumb， and the operation does not require changing the grip posture. The braking system I adopted a progressive design to avoid equipment shaking caused by sudden stops.
