Device for fixing a wiping felt and assembly including the same
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for fixing felt pads on crepe pans are difficult to implement due to the stiffness of the felt, which can lead to partial detachment and excessive fat retention, causing food quality issues.
Innovation Solution
A device with a gripping member and a pinching member that are selectively movable to pinch or release the felt, featuring a removable stud and a cam path guide groove, allowing for easy attachment and detachment of the felt without storing excess fat.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a groove is used to tightly engage the felt periphery, then the felt is securely fixed, but the felt is difficult to implement and may partially detach
Solution Approach 1:
The device employs a dynamic pinching mechanism where two pinching members can move relative to each other between open and closed positions. This allows the felt to be easily inserted when the members are separated, then securely clamped when brought together, resolving the contradiction between easy attachment and secure fixation.
Solution Approach 2:
The pinching members act as intermediary elements between the felt and the device body. Instead of directly engaging the felt periphery in a groove, the pinching members provide a controlled clamping action that secures the felt without requiring complex groove engagement, thus improving ease of manufacture while maintaining reliability.
2Stability of the object's composition
If a thick felt is used to provide structural stability, then the felt is easier to handle, but excessive fat is retained and stored for long time
Solution Approach 1:
The invention enables the use of thin felt by changing the structural parameter from thickness-based stability to mechanism-based security. The pinching mechanism provides the necessary stability and security without requiring increased felt thickness, thereby reducing fat retention and preventing degradation while maintaining handling stability.
3Ease of operation
If the pinching member is movable to enable easy felt replacement, then the device is easier to operate, but the structure becomes more complex
Solution Approach 1:
The pinching mechanism is designed with dynamic elements that allow movement between open and closed states for easy felt replacement. The cam profile converts simple rotational motion into the required pinching action, providing ease of operation while keeping the mechanical structure relatively simple through efficient use of cam geometry rather than complex actuation systems.
