Solution Overview
Problem
Existing food processing devices face challenges in achieving a sealed engagement between vacuum conduits, which can lead to air leakage and potential damage during assembly, compromising the effectiveness of the vacuum mechanism.
Innovation Solution
The design incorporates displaceable engaging ends for the first and second vacuum conduits, allowing for engagement only when correctly aligned, utilizing a driven actuator and resilient members to ensure secure connection and minimize risk of damage, with optional modular and flexible components for enhanced functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a spigot and socket joint is used to seal the vacuum conduits, then air leakage is prevented, but the risk of damage during assembly increases
Solution Approach 1:
The patent introduces a displaceable engagement mechanism with a cushioning element that absorbs impact forces during assembly. The engaging end can move relative to the conduit body, allowing misaligned or forceful assembly attempts to be cushioned rather than causing damage to the spigot and socket joint. This prior cushioning protection maintains the reliability of the sealed engagement while reducing assembly damage risk.
2Stability of the object's composition
If the vacuum conduits are rigidly connected, then structural stability is improved, but adaptability to assembly variations is reduced
Solution Approach 1:
The patent implements a dynamic engagement system where the engaging end of the vacuum conduit can displace relative to the main conduit body. This displacement capability allows the rigid conduit structure to adapt to assembly variations and tolerances while maintaining structural stability during operation. The dynamic element provides flexibility during assembly but ensures rigidity when engaged, resolving the contradiction between structural stability and assembly adaptability.
3Manufacturing precision
If the engaging ends are fixed in position, then manufacturing precision is improved, but ease of operation during assembly is reduced
Solution Approach 1:
The displaceable engaging end allows operators to easily assemble the vacuum conduit system without requiring high precision alignment, while the engagement mechanism itself maintains precise sealing when connected. The dynamic displacement capability absorbs alignment tolerances during assembly, making operation easier, while the engaged position ensures manufacturing precision for the sealed connection.
Solution Approach 2:
The patent introduces an intermediary displaceable element between the fixed conduit body and the engaging end. This intermediary component absorbs the complexity of precision positioning, allowing the main conduit structure to remain simple and fixed while the intermediary element handles the precise engagement and sealing function, improving both ease of operation and maintaining engagement precision.
