Mussel Feeding via Inhalation Flow Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mussel aquaculture systems are inefficient and invasive, leading to food waste and water pollution, as they require labor-intensive and costly algae production, with suspended feeding methods that do not optimize supply to individual mussels, causing unnecessary stress and environmental impact.
Innovation Solution
A device with a supply pipe having a supply opening positioned near the mussel's inhalation flow, allowing direct and non-invasive feeding, using a pipette for precise delivery and a metering valve for controlled dosing, which can be adjusted based on mussel size and flow rates, reducing waste and optimizing resource use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If algae are suspended in flowing water for feeding mussels, then the feeding process can be simplified, but a large portion of algae is not consumed leading to food waste and water pollution
Solution Approach 1:
The invention divides the feeding system into individual feeding units, each with its own supply pipe and opening. Each mussel receives food individually through its own channel, preventing food waste and allowing precise control of food distribution to each organism.
Solution Approach 2:
The supply opening of each supply pipe is positioned at a specific distance in front of the mussel in the inhalation flow area, creating a localized food delivery zone. This ensures food is delivered precisely where mussels can consume it, preventing dispersion and waste in the water column.
2Productivity
If a hole is drilled into the mussel shell for feeding tube insertion, then direct food delivery to the mussel interior is achieved, but the procedure is complex and invasive harming the mussel
Solution Approach 1:
Instead of inserting the feeding tube into the mussel through shell drilling, the invention inverts the approach by positioning the supply opening in the inhalation flow path in front of the mussel. The mussel actively draws food-laden water into its shell through its natural inhalation mechanism, eliminating invasive procedures.
Solution Approach 2:
The mussel's natural inhalation behavior is utilized to draw food-laden water into its shell. The system leverages the mussel's own physiological actions (opening shell valves to create inhalation flow) to achieve food delivery without external intervention or invasive procedures.
3Device complexity
If mussels are fed in groups with suspended algae, then the feeding system is simpler to operate, but individualized feeding optimization cannot be achieved
Solution Approach 1:
The feeding system is segmented into multiple independent supply pipes, each serving an individual mussel. This modular structure allows individualized feeding control for each mussel while maintaining overall system simplicity through standardized components and repetitive units.

AI summary
Feeding mussels (Bivalvia) with food suspended in the water is ineffective and leads to water pollution. It is known to force-feed the mussels through a bore in their shell valves. According to the invention, a non-invasive solution is proposed in which the supply opening (14) of the supply tube (13) is arranged near the mussel (02) in the area of its inhalation stream (10), without touching the shell valves (08). The mussels (02) are preferably fixed in a frame (05), and pipettes (16) with the supply openings (14) are preferably arranged in front of them. Either the mussels (02) can be conditioned to the feeding, or contact or non-contact sensors (21) are provided, the signals from which, when the mussel (02) opens, actuate metering valves (25). The dosage depends primarily on the size of the mussel (02) and on the strength of the inhalation flow (10) and the water current (11).A very efficient supply of mussels (02) is achieved, which is suitable for both rearing and feeding, conserves resources, and enables the establishment of aquaculture facilities even in water-sensitive areas.
