Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual climbing method is used for fruit picking, then picking can be performed, but safety is poor and labor intensity is high
Solution Approach 1:
The patent replaces manual mechanical climbing with a ground-based vibrating machine that uses vibration to shake fruits from the tree. The machine transmits vibrating force through a transmission rod to the tree trunk, causing fruits to detach naturally without requiring workers to climb the tree, thus improving safety while maintaining picking effectiveness.
Solution Approach 2:
The patent employs a vibrating mechanism that generates oscillating motion to shake the tree trunk and branches, causing Camellia oleifera fruits to detach. The vibration source produces controlled vibrations that are transmitted through the tree structure, enabling fruit harvesting without manual climbing and reducing labor intensity and safety risks.
2Reliability
If knocking method with stick is used, then safety is improved by avoiding climbing, but branches and buds are damaged
Solution Approach 1:
The patent uses controlled vibration instead of direct mechanical impact. The vibrating mechanism generates oscillating forces that are transmitted through the tree trunk, causing fruits to detach through vibration-induced shaking rather than direct knocking. This approach avoids the concentrated impact forces that damage branches and buds while still achieving effective fruit detachment.
Solution Approach 2:
The patent employs periodic vibrating motion rather than continuous or impact-based action. The vibration source generates rhythmic oscillations at specific frequencies that resonate with the tree structure, gradually building up motion to detach fruits. This periodic action is gentler than continuous knocking and allows the tree structure to respond without sustaining damage to branches and buds.
3Productivity
If large vibrating machine is used, then picking efficiency is improved, but portability is poor for steep slopes
Solution Approach 1:
The patent divides the vibrating machine into separable components: a vibrating source unit that can be transported to the harvesting location and a transmission rod that can be assembled on-site. The transmission rod can be segmented into multiple sections that are connected together to reach the desired height. This segmentation allows the machine to maintain high picking efficiency while improving portability for steep slope environments.
Solution Approach 2:
The patent employs a telescopic or adjustable transmission rod that can change its effective length and configuration. The rod can be extended or retracted, and adjusted in height, allowing the machine to adapt to different tree heights and terrain conditions. This dynamic adjustability enables the use of a smaller, more portable vibrating source while maintaining the picking efficiency needed for tall trees on steep slopes.

AI summary
Disclosed is a portable telescopic push-pull vibrating-shaking type Camellia oleifera fruit picking and beating machine. The machine includes a picking and beating head, a gear shifting mechanism, a power transmission and picking and beating rod, a direct current motor, a control system, a handheld grip, and a lithium battery. A battery supplies power to enable the direct current motor to rotate, the direct current motor drives a worm and worm wheel mechanism in the gear shifting mechanism to rotate through a power transmission rod, the worm and worm wheel mechanism drives the picking and beating head to achieve reciprocating push-pull motion, such that the picking and beating rod can pull a branch to generate push-pull and vibration to pick Camellia oleifera fruit down. The picking and beating head is provided with a force sensor capable of monitoring picking and beating strength at any time.
