Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for cleaning pond sediment are inadequate for residential ponds, as they face challenges with access to deeper areas, suction loss, efficiency, debris distribution, and water return, and gravity-fed systems are expensive and difficult to install.
Innovation Solution
A portable, powered vacuum device with adjustable elevation and a frame supported by wheels, equipped with a pump system and suction end pieces that can handle pebbles and stones, and a filtration system to manage debris, allowing for efficient sediment removal without damaging the pond liner.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a portable powered vacuum device with wheels is used, then ease of operation and maneuverability improve, but device complexity increases compared to simple hose devices
Solution Approach 1:
The device is divided into separate functional modules: a powered vacuum unit with motor and pump, a wheeled frame for mobility, a suction head with adjustable elevation, and a filtration system. This segmentation allows each component to be optimized independently while maintaining overall ease of operation through modular assembly and disassembly.
Solution Approach 2:
The wheeled frame acts as an intermediary between the operator and the vacuum system, providing mechanical support and mobility without requiring the operator to directly handle heavy equipment. The adjustable elevation mechanism serves as an intermediary to maintain optimal suction distance from the pond bottom, reducing the need for manual adjustment during operation.
2Productivity
If the suction end is positioned close to the pond bottom, then sediment removal efficiency improves, but the risk of damaging the pond liner increases
Solution Approach 1:
The suction head is equipped with an adjustable elevation mechanism that allows dynamic adjustment of the distance between the suction end and the pond bottom. This enables the operator to maintain optimal suction efficiency while preventing the suction end from contacting or damaging the liner, adapting to different pond conditions in real-time.
Solution Approach 2:
The device allows changing the operational parameter of suction head elevation to balance between sediment removal efficiency and liner protection. By adjusting this parameter, the system can operate at different distances from the bottom surface, optimizing performance while avoiding harmful contact with the liner.
3Productivity
If a filtration system is added to handle pebbles and stones, then the ability to remove larger debris improves, but device complexity and weight increase
Solution Approach 1:
The filtration system is designed to extract and separate larger debris such as pebbles and stones from the water-sediment mixture before it enters the pump. This extraction function protects the pump from damage and allows the device to handle a wider range of debris sizes, with the filtered materials being discharged separately or retained for later removal.
4Reliability
If the motor is positioned out of the water, then safety and reliability improve, but access to deeper portions of the pond becomes difficult
Solution Approach 1:
The device uses a wheeled frame that contacts the pond bottom, providing a stable platform that extends the operator's reach into deeper areas. The wheels distribute the device's weight and provide mechanical support, allowing the vacuum unit to be positioned in deep water while the operator remains on or near the surface, effectively adding a dimensional aspect to the operation.

AI summary
An apparatus for removing a layer of sediment which has settled on the bottom of a large water body that includes a structural frame configured to contain a bottom water flow and avoid a re-suspension of sediment outside the vicinity of the structural frame. The structural frame has a control zone configured for containing liquid and suspended particles dispersed during removal of bottom sediment in a suctioning area that is at least about 3 square feet. A sediment removing vacuum unit is operably associated with the structural frame to conduct a suctioned bottom water flow.
