Irrigation Wrench Angled Handles Reduce Turning Radius
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing irrigation tools require significant terrain removal around sprinkler head caps due to large turning radii, limiting the ability to replace or realign sprinkler components efficiently, as they need ample space to apply torque effectively.
Innovation Solution
An irrigation wrench with angled handles and pivot-connected gripping jaw members that reduce the turning radius while maintaining sufficient torque, featuring lugs and teeth for secure engagement with the cap, allowing for efficient loosening and tightening of sprinkler head assemblies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If traditional irrigation tools are used to loosen the cap, then sufficient torque can be applied, but a large turning radius is required which necessitates removal of significant terrain surrounding the sprinkler head
Solution Approach 1:
The tool transitions from a conventional linear arrangement to a multi-dimensional configuration with handles extending in different spatial dimensions. The first handle extends in a first direction while the second handle extends in a second direction different from the first direction, allowing the tool to apply torque within a smaller planar footprint by utilizing three-dimensional spatial arrangement rather than requiring extended linear space.
Solution Approach 2:
The tool features nested structural elements where the first and second handles are positioned within or alongside each other in a compact arrangement. The gripping members at the ends of the handles engage with the cap features, while the handles themselves are arranged to minimize the overall envelope of the tool, effectively nesting functional components to reduce the turning radius requirement.
2Area of stationary object
If terrain removal is minimized to preserve landscape, then the turning radius is reduced, but the ability to apply sufficient torque is compromised
Solution Approach 1:
The tool incorporates curved or angled geometries in the handle arrangements and gripping member orientations that allow rotational motion to be achieved within a smaller radius. The non-linear, curved paths enabled by the multi-directional handle configuration allow the user to apply torque effectively without requiring a large linear turning space, converting the constraint into a design advantage.
Solution Approach 2:
The tool divides the torque application function across multiple segmented components - the first handle with its gripping member, the second handle with its gripping member, and the pivot connection between them. This segmentation allows each component to contribute to torque application independently, distributing the mechanical advantage across multiple points of engagement with the cap rather than relying on a single long lever arm.
3Force
If the tool length is increased to provide greater torque, then sufficient loosening force is achieved, but the turning radius increases requiring more terrain removal
Solution Approach 1:
The tool employs asymmetric handle configurations where the first and second handles extend in different directions from the pivot point, creating an asymmetric geometry that optimizes torque application. This asymmetric arrangement allows the handles to be positioned at optimal angles relative to the cap features and user application force, achieving maximum mechanical advantage without requiring symmetric extension of handle lengths that would increase overall tool length and turning radius.
Solution Approach 2:
The gripping members are pre-configured with engagement features (such as teeth or gripping surfaces) that are designed to engage with corresponding features on the cap before torque application begins. This preliminary engagement ensures that the torque is applied efficiently through properly positioned contact points, maximizing the effectiveness of the available handle length without requiring excessive extension.

The irrigation wrench enables efficient cap loosening and tightening with a smaller turning radius, minimizing terrain disruption and providing adequate torque, thus facilitating easier maintenance of sprinkler systems without extensive terrain removal.
Implementation Method 1
The handles rotate about the pivot to increase or decrease a separation distance between the gripping jaw members
Implementation Method 2
Gripping teeth are formed on the inner side surface of each gripping jaw member
