Offset Motor Pole Saw Compact Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current telescoping pole saws cannot fit within the tubes mounted on utility vehicles in a fully assembled state, posing challenges for efficient storage and accessibility on utility vehicles like those used in tree service and landscape maintenance.
Innovation Solution
A telescoping pole saw design that includes a housing with an electric motor, a work element, and a drive shaft extending between the motor and the work element, allowing it to fit within a cylinder with a diameter of no greater than 6 inches in a fully assembled state, with the motor axis offset to minimize the profile and enable compact storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If telescoping pole saws are designed with conventional configurations, then they provide adequate functionality and power, but they cannot fit within tubes mounted on utility vehicles in a fully assembled state
Solution Approach 1:
The pole saw is divided into multiple telescoping pole segments that can nest within each other, allowing the tool to be compacted to a small diameter for storage in tubes while maintaining full length and functionality during use. The housing and work element are designed as separate removable components that can be stored independently or nested together.
Solution Approach 2:
The pole segments are designed to telescope and nest within each other like nested dolls, with each segment containing the next smaller segment. The housing and work element can also be positioned to nest within the pole structure, achieving a compact fully-assembled storage configuration that fits within tube-mounted containers on utility vehicles.
2Volume of moving object
If telescoping pole saws are made compact to fit in tubes, then storage space is optimized, but the tools become difficult to access and retrieve
Solution Approach 1:
The pole segments are designed with dynamic telescoping mechanisms that allow quick extension and retraction. The segments can be rapidly deployed from compact storage to full operational length, and the housing and work element can be quickly attached or detached, minimizing the time required to retrieve and prepare the tool for use.
3Shape
If the motor axis is centered on the longitudinal axis, then the design is simpler, but the profile is too large to fit within 6-inch diameter cylinders
Solution Approach 1:
The motor axis is deliberately offset from the longitudinal axis of the pole saw, creating an asymmetric configuration. This offset positioning allows the motor housing to be arranged more compactly, reducing the overall diameter of the tool so it can fit within 6-inch diameter storage tubes while still providing adequate power and functionality.
