Livewell Pump Snap-Fit Base and Rotating Pickup Tube
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing livewell/baitwell pumps are difficult to install and replace due to their fixed base design, which requires the use of mounting screws, leading to time-consuming and costly processes, and potential screw vibration issues.
Innovation Solution
A pump cartridge assembly with flexible cantilever snap tabs and an anti-rotation locking ring that allows for rotatable coupling with the pickup tube, eliminating the need for screws and enabling easy positioning and secure locking without vibration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mounting screws are used to secure the pump base, then the pump can be firmly fixed in position, but the installation and replacement process becomes time-consuming and complex
Solution Approach 1:
The patent removes the mounting screws entirely from the pump base design. Instead of using traditional screw fastening, the pump base incorporates a snap-fit mechanism that allows the pump to be securely mounted directly into the livewell without any separate fastening components, thereby eliminating installation time while maintaining firm fixation.
Solution Approach 2:
The pump base features self-aligning and self-securing characteristics through its snap-fit design. The base automatically positions itself and secures into place during installation without requiring separate fastening operations, making the installation process intuitive and time-efficient while ensuring reliable mounting.
2Reliability
If mounting screws are used to secure the pump base, then the pump can be firmly fixed, but the possibility of screws vibrating loose increases
Solution Approach 1:
By completely removing the mounting screws from the design, the patent eliminates the source of vibration-related problems. The snap-fit mechanism replaces screw fastening, thereby eliminating the harmful factor of screws vibrating loose while maintaining secure pump fixation in the livewell.
3Manufacturing precision
If the pickup tube position is fixed at the manufacturer, then manufacturing precision can be maintained, but field adjustment and repositioning become difficult and time-consuming
Solution Approach 1:
The patent makes the pickup tube dynamically adjustable by incorporating a rotation mechanism that allows the tube to be repositioned to various angles and orientations. The tube can rotate within a defined range while maintaining a secure connection, enabling field adjustment without requiring manufacturer intervention or complex repositioning procedures.
Solution Approach 2:
The pickup tube assembly is segmented into adjustable components that can be independently positioned. The tube can be rotated and repositioned relative to the pump body, allowing flexible adjustment in the field while maintaining manufacturing precision through standardized connection interfaces.
4Stability of the object's composition
If the pump base is made fixed and secured by screws, then structural stability is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent eliminates the complex screw mounting mechanism entirely, replacing it with a simple snap-fit base design. This reduction in components decreases device complexity and manufacturing cost while maintaining base stability through the inherent mechanical interlock of the snap-fit structure.
Solution Approach 2:
The snap-fit base incorporates flexible elements that allow the base to deform slightly during installation and then lock into place, providing structural stability without requiring rigid fastening mechanisms. This flexible design simplifies the overall structure while ensuring secure mounting.

AI summary
A livewell/baitwell pump for installing in a boat or other suitable vessel or apparatus, the pump comprising a pump cartridge assembly having a cartridge body with one or more flexible cantilever snap tabs and with a discharge hose; a pickup tube having an interior cavity with one or more undercuts and with a pickup tube; and each cantilever snap tab of the cartridge body being releasably coupled to a respective undercut of the pickup tube when the cartridge body is inserted into the interior cavity for permitting rotation of the pickup tube and the cartridge body in relation to one another for quickly and easily coupling the discharge hose and the pickup tube in any direction to corresponding hosing or tubing during installation of the pump in the boat or other suitable vessel or apparatus. The pump further comprises an anti-rotation locking ring that permits the rotation of the pickup tube to a desired orientation in relation to the pump cartridge assembly when the anti-rotation locking ring in a first position, and that prevents rotation of the pickup tube once in the desired direction in relation to the pump cartridge assembly when in a second position.
