Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hygienic motors in environments requiring frequent high-temperature and high-pressure cleaning cycles face challenges in maintaining pressure equilibrium due to sealed designs, leading to excessive wear and maintenance costs, as conventional venting solutions compromise the motor's sealed condition.
Innovation Solution
A cable vent connector system that includes a vent tube and breathable membrane to allow air passage while preventing moisture ingress, enabling pressure equilibrium between the motor's interior and atmosphere without exposing the motor to harsh cleaning environments, and a drive cable guide insert for secure electrical connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sealed motor design is used to prevent bacteria infiltration, then hygiene standards are met, but pressure equilibrium cannot be maintained leading to excessive wear
Solution Approach 1:
A breathable membrane is introduced as an intermediary element between the motor interior and exterior environment. This membrane allows water vapor transmission to maintain pressure equilibrium while blocking liquid water and bacteria, thus resolving the contradiction between sealed hygiene requirements and pressure balance needs
Solution Approach 2:
The patent employs a breathable membrane (thin film) that provides selective permeability - allowing vapor passage while blocking liquids and contaminants. This flexible film solution enables the motor to maintain both hygiene sealing and pressure equilibrium simultaneously
2Stability of the object's composition
If a vent opening is provided on the motor housing to achieve pressure equilibrium, then pressure balance is maintained, but the motor becomes exposed to cleaning cycles and damage occurs
Solution Approach 1:
The breathable membrane acts as a mediator that enables pressure equilibrium through vapor transmission while protecting the motor interior from direct exposure to harmful cleaning agents, liquids, and bacteria during high-temperature and high-pressure cleaning cycles
3Reliability
If the motor is completely sealed to protect internals during cleaning, then durability during cleaning is improved, but pressure differential causes excessive wear
Solution Approach 1:
The breathable membrane provides a flexible sealing solution that protects the motor during cleaning cycles while allowing pressure equalization, thereby extending the motor's service life by preventing both cleaning damage and wear from pressure differentials
