Blower Filter Housing Adapter Module Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing housing designs for blower filter devices have a high risk of leaks and contamination due to multiple sealing points and exposed contact elements, which complicates operation and increases the risk of damage and accidents.
Innovation Solution
A housing design that integrates an adapter module with a connector for non-destructive attachment to the contact element, reducing the number of sealing points and allowing only one housing through-opening for data, signal, and power transmission, while protecting the contact element from contamination by covering it with the adapter module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple housing through-openings are provided for operating status display, control element, and contact element, then each element can be individually accessed and sealed, but the number of sealing points increases leading to higher leak risk
Solution Approach 1:
The patent combines the operating status display, control element, and contact element into a single integrated functional unit that is accommodated in one housing through-opening. This merging reduces the number of sealing points from three separate openings to one sealing point, thereby improving sealing reliability while maintaining ease of operation through the integrated interface.
Solution Approach 2:
The single housing through-opening serves multiple functions by accommodating the entire functional unit including display, control, and contact elements. This multi-functional design eliminates the need for separate openings for each element, reducing sealing complexity while preserving all operational capabilities.
2Ease of operation
If contact elements are exposed on the housing exterior, then they are easily accessible for connection, but they are vulnerable to contamination from the housing environment
Solution Approach 1:
The contact element is nested within the functional unit that is itself accommodated in the housing through-opening. The functional unit acts as a protective enclosure for the contact element, shielding it from environmental contamination while keeping it accessible for connection through the single opening.
Solution Approach 2:
The functional unit serves as an intermediary structure between the housing environment and the contact element. It provides a protected interface that allows external connection while preventing direct exposure of the contact element to contaminants in the housing environment.
3Object-affected harmful factors
If additional cover caps or lids are provided to protect contact elements, then contamination is prevented, but device complexity and number of components increase
Solution Approach 1:
The protective function previously requiring separate cover caps or lids is merged into the functional unit structure itself. The functional unit integrates the contact element protection, display, and control functions into a single component assembly, eliminating the need for additional protective covers and reducing overall device complexity.
