Telescoping Paddle Pump With Hollow Handle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing combination paddle and pump devices require auxiliary hoses and necessitate removal from the water to function effectively, limiting their versatility and space efficiency.
Innovation Solution
A self-contained combination paddle and pump with a telescoping handle featuring a hollow interior and opposed check valves, allowing liquid to be suctioned and expelled without hoses, enabling operation within the water without removing the paddle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a combination paddle and pump device is designed with inlet and outlet at the bottom of the paddle, then the device can pump water, but auxiliary hoses must be attached and the paddle must be removed from the water to function
Solution Approach 1:
The outlet is relocated from the bottom dimension to the handle dimension, allowing the pump to discharge water vertically upward rather than horizontally at the bottom. This dimensional change enables the paddle to remain submerged while pumping, as the outlet extends above the water line through the handle structure.
Solution Approach 2:
The handle is designed to serve dual functions: as a structural component for paddling and as a conduit for water discharge. This multi-functionality eliminates the need for separate hoses and allows the device to operate effectively both as a paddle and as a self-contained pump.
2Adaptability or versatility
If a combination paddle and pump device is designed with inlet at the bottom, then the device can suction water, but the paddle must be lifted out of the water to expel the water
Solution Approach 1:
The telescoping handle with outlet allows continuous pumping action without interruption. The user can maintain the paddle in the water and simply telescope the handle to discharge water, eliminating the time-consuming cycle of lifting the paddle out, expelling water, and re-submerging it.
3Ease of manufacture
If separate paddle and pump devices are used, then each device can be optimized for its specific function, but more space is required to store both devices
Solution Approach 1:
The pump mechanism is integrated into the paddle structure itself, with the handle serving as both the paddling grip and the pump outlet conduit. This merging of functions into a single unified device eliminates the need to carry separate paddle and pump equipment, reducing storage space while maintaining functional optimization.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device efficiently pumps liquid from one place to another while serving as a paddle, eliminating the need for separate hoses and allowing continuous use in water, enhancing versatility and space efficiency.
Implementation Method 1
Within the hollow interior of the handle, a pair of check valves are provided. One check valve opens when the handle is extended and the other opens when the handle is retracted.

AI summary
A combined paddle and pump can be used to propel a small boat. The handle telescopes with a locking nut that may be loosened to allow extension and retraction of the handle. The handle is hollow throughout and a pair of check valves are provided. One check valve opens when the handle is extended and the other opens when the handle is retracted. When one check valve is open, the other is closed. When the distal end of the paddle is placed within a volume of water, extension and retraction of the handle results in a liquid first being sucked into the hollow interior of the handle and then propelled out of the handle.
