Composite Sprayer Boom Support Resolving Weight and Corrosion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural sprayer boom supports are heavy due to metal construction, leading to buckling, vibrations, and breakage, limiting length, speed, and requiring frequent repairs, while being corrosive and inefficient.
Innovation Solution
The use of composite material articulated arms with a rectangular tube geometry and rounded vertices, made from carbon fibre, fibreglass, or aramid fibre with epoxy or polyester resin, reducing weight and maintaining horizontality without a latticed structure, along with a repair kit for easy field repairs and resistance to corrosive products.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If metal latticed structure is used for boom support, then structural strength and horizontality are maintained, but weight increases significantly
Solution Approach 1:
The patent replaces traditional metal latticed structures with composite material boom supports. The composite material provides sufficient structural strength while significantly reducing weight, eliminating the need for heavy latticed frameworks and thereby resolving the contradiction between strength and weight.
Solution Approach 2:
The patent changes the material parameter from metal to composite material, which fundamentally alters the weight-to-strength ratio. This parameter change allows the boom support to maintain required strength while reducing weight, directly addressing the technical contradiction.
2Strength
If metal structure is used for boom support, then structural integrity is maintained, but susceptibility to corrosion increases
Solution Approach 1:
The patent employs composite materials that inherently possess superior corrosion resistance compared to metal. The composite structure maintains structural integrity while being immune to the corrosive effects of agricultural chemicals, thereby resolving the contradiction between strength and corrosion resistance.
3Stability of the object's composition
If heavy metal structure is used, then stability during operation is improved, but speed and maneuverability decrease
Solution Approach 1:
The composite material boom support achieves an optimal balance between stability and speed. The reduced weight improves acceleration and maneuverability while the material properties and structural design maintain operational stability, resolving the contradiction between stability and speed.
4Force
If metal latticed structure is used, then load-bearing capacity is sufficient, but frequency of breakage and repair needs increases
Solution Approach 1:
The composite material boom support exhibits superior breakage resistance and fatigue life compared to metal structures. The material's inherent properties and the design maintain full load-bearing capacity while significantly reducing breakage frequency and repair needs, resolving the contradiction between force capacity and reliability.

AI summary
A sprayer boom support for an agricultural sprayer including two articulated arms that are coupled in an articulated manner on both sides of the sprayer, wherein each articulated arm is comprised of bar sections that are formed in a composite material consisting of a reinforcing agent chosen from carbon fibre, fibreglass, aramid fibre, boron fibre or a combination thereof, and a matrix of epoxy, vinyl ester, phenolic or polyester resin, the bar sections having a tube geometry with a substantially rectangular cross section with rounded vertices and arched sides, the length of two of its equal sides being constant along the bar section.
