Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional fish pots for catching cod are heavy, rigid, and inefficient, requiring increased time and effort to fulfill fishing quotas in harsh arctic environments, and do not effectively utilize deck space for storage.
Innovation Solution
An expandable fish pot design featuring a main frame structure with an extendable frame and floating elements, adjustable pipes, and mesh panels with one-way entrances, allowing for increased internal volume and fishing capacity without additional storage needs, utilizing steel bars and buoyant materials for enhanced buoyancy and retrieval.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the fish pot is made larger to increase fishing capacity, then more fish can be caught, but the pot requires more deck storage space
Solution Approach 1:
The fish pot employs an extendable frame structure that transforms from a compact configuration during storage to an expanded configuration during fishing operations. The frame includes extendable sections with joints that allow the pot to increase its internal volume when deployed, while maintaining a smaller footprint on the deck during transport and storage.
Solution Approach 2:
The extendable frame structure utilizes nested components where telescoping bars and joints allow sections to be stored within each other in a compact arrangement. When deployed, these nested sections extend outward to form the larger fishing volume, effectively hiding the increased size during storage while providing it during operation.
2Weight of moving object
If the fish pot is made heavier to sink to the sea floor, then it provides sufficient weight for fishing, but it becomes harder to handle and retrieve
Solution Approach 1:
The fish pot incorporates buoyant elements attached to the frame structure that provide upward buoyant force to counterbalance the weight of the heavy steel frame. These buoyancy elements allow the pot to be easily retrieved by hauling on the rope without requiring excessive force, while still enabling the frame to sink when deployed due to its overall negative buoyancy when the buoyant elements are not engaged.
3Strength
If the fish pot uses a rigid frame structure for strength, then it can hold fish, but it cannot increase volume without increasing storage space requirements
Solution Approach 1:
The frame structure transitions from a static rigid design to a dynamic extendable design. The frame includes joints and connection points that allow controlled movement and extension of frame members. When deployed, the frame maintains sufficient rigidity to hold fish, but during storage, the frame members can be positioned in a compact, nested arrangement that reduces the volume occupied on the deck.
4Productivity
If fishing time is reduced to meet quotas, then productivity increases, but the fish pot must be more efficient to compensate
Solution Approach 1:
The extendable frame structure adds vertical dimension to the fish pot by extending upward from the sea floor. This increased height creates additional internal volume and allows more fish to enter through the mesh panels, thereby increasing the fishing capacity and efficiency of each deployment without requiring multiple pots.

Function Achieved in This Case
The expandable fish pot increases fishing capacity, reduces time spent at sea, and maintains efficient deck storage by extending internally when submerged and retracting during retrieval, improving fishing efficiency and safety in challenging conditions.
Implementation Method 1
the extendable frame structure is provided with a number of floating elements extending the extendable frame structure from the main frame structure when the pot is immersed in water
