Hollow Roller Pin Bone Removal with Internal Fluid Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for removing pin bones from fish fillets are complex, difficult to clean, and prone to high operating temperatures due to encapsulated electric motors, which reduces their service life and fails to maintain hygienic standards.
Innovation Solution
A compact device design with a hollow roller unit that integrates the drive unit internally, utilizing a fluid-permeable interior for cooling and heat dissipation, ensuring reliable operation and easy cleaning by using a fluid as a cooling medium to maintain specified temperatures and prevent overheating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electric motor is completely encapsulated or arranged spatially separate from the roller unit, then the motor is protected from contamination and moisture, but the device becomes complex and difficult to clean, and heat dissipation is impeded leading to high operating temperatures
Solution Approach 1:
The drive unit is integrated directly into the roller unit, merging two previously separate components into one unified structure. This eliminates the need for separate motor housings and complex sealing arrangements, while the fluid-cooled design provides protection without requiring complete encapsulation.
Solution Approach 2:
A fluid cooling system is implemented where coolant flows through channels in the roller unit to remove heat from the drive unit. This hydraulic approach provides both cooling and protective functions simultaneously, replacing the need for complex thermal management and sealing systems.
2Reliability
If the electric motor is completely encapsulated, then protection from moisture and dirt is improved, but heat dissipation is impeded leading to reduction in service life
Solution Approach 1:
The roller unit incorporates fluid flow channels that allow coolant to pass through the interior structure, creating a porous-like flow path. This enables continuous heat removal from the drive unit while maintaining structural integrity and protection from contamination.
Solution Approach 2:
A fluid coolant is introduced as an intermediary medium between the drive unit and the external environment. The coolant absorbs heat from the drive unit and transports it away, providing thermal management without requiring direct thermal contact with the external environment or complex heat sinks.
3Device complexity
If the roller unit is designed as hollow with integrated drive unit, then compactness and ease of cleaning are improved, but protection against moisture and dirt ingress must be maintained
Solution Approach 1:
The drive unit and roller unit are merged into a single integrated component, eliminating separate housings and joints that would complicate cleaning. The fluid-cooled design provides protective functionality without requiring additional encapsulation layers or seals.
Solution Approach 2:
The fluid cooling system serves dual purposes: thermal management and protective sealing. The continuous fluid flow creates a protective barrier that prevents contamination ingress while the integrated design maintains compactness and ease of cleaning.
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 solution provides a compact, easy-to-clean device that effectively protects the drive unit from moisture and dirt, maintains optimal operating temperatures, and prevents overheating, thereby extending the service life and ensuring reliable operation while removing pin bones without heating the fish fillets.
Implementation Method 1
the fluid is set up as a cooling medium in order to absorb the waste heat produced by the drive unit and to transport it away from the interior
Implementation Method 2
The fluid continuity of the interior means that both the drive unit and the roller unit are always kept at a specified operating temperature or a specified operating temperature range by supplying and discharging a fluid
