Modular Backpack Sprayer Frame With Concave Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Backpack sprayers require frequent tank cleaning and chemical segregation due to the need to switch between different pesticide solutions, leading to waste, contamination risks, and limited configuration options due to manufacturing inefficiencies and design costs.
Innovation Solution
A modular frame for backpack sprayers that allows for versatile mounting of various tank and pump configurations, featuring a frame plate with receiving channels, a support member, and a mounting member with a concave portion to securely attach tanks and pump units, enabling easy assembly and use of single or dual tanks with internal or external pumps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single tank is used for storing both water and chemical concentrate, then the device complexity is reduced, but chemical waste and contamination risks increase due to the need for frequent cleaning between different pesticide solutions
Solution Approach 1:
The patent divides the fluid storage system into separate tanks: a water tank for diluent and a chemical concentrate tank for pesticide solutions. This segmentation allows each tank to be dedicated to a specific fluid type, eliminating the need to clean a single tank between different chemical applications and preventing cross-contamination.
Solution Approach 2:
The chemical concentrate is extracted from the water tank and stored in a separate concentrate tank. A metering device then adds the required amount of chemical to the water flow, allowing the chemical to remain isolated from the water tank and minimizing contamination risks.
2Adaptability or versatility
If multiple sprayer configurations are supported, then adaptability increases, but manufacturing complexity and production costs increase
Solution Approach 1:
The patent employs a universal mounting frame with standardized mounting members that can accommodate various tank configurations (single tank, dual tanks) and pump types (manual, electric, battery-powered). This multi-functional design allows one frame structure to support multiple sprayer configurations, reducing the need for dedicated frames for each configuration and simplifying manufacturing.
Solution Approach 2:
The mounting members are designed with adjustable and interchangeable components that can be configured for different tank and pump arrangements. This dynamic adaptability allows the same frame to be reconfigured for various sprayer types without requiring completely different manufacturing processes.
3Reliability
If frequent tank cleaning is performed to switch between pesticide solutions, then chemical contamination is prevented, but time consumption and productivity decrease
Solution Approach 1:
By segmenting the fluid storage into separate water and chemical concentrate tanks, the system eliminates the need to clean a single tank when switching between different pesticide solutions. Each tank can be dedicated to its specific fluid, allowing rapid solution changes without cleaning operations.
Solution Approach 2:
The system allows for easy removal and replacement of tank components or entire tanks when switching between different chemical applications. Rather than cleaning the tank thoroughly, users can simply remove the old tank and attach a new one, significantly reducing the time required to switch between different pesticide solutions.

AI summary
A modular frame for a backpack sprayer system includes a frame plate having a front surface, a back surface and first and second side edges. A first receiving channel is located along the first side edge and a second receiving channel is located along the second side edge. A support member has a first arm which is received within the first receiving channel and a second arm which is received within the second receiving channel. A stand portion extends at an angle relative to the first and second arms. A mounting member is coupled to the front surface of the frame plate and mounts a tank and a pump unit thereon. The mounting member includes opposing left and right sides, a planar top face and a front face including a concave portion to receive at least a portion of one or both of the tank and the pump unit.
