Solution Overview

Problem

Conventional filter assemblies face challenges in easily securing and unsecuring removable filter members, such as filter bags, from filter vessel assemblies, particularly under difficult conditions, indicating a need for improved systems or designs that facilitate secure and convenient attachment and detachment.

Innovation Solution

The development of a filter vessel assembly with a releasable locking assembly that includes a supporting assembly or basket assembly, featuring a locking mechanism with securing members and a gasketing system, allowing for easy and secure attachment and detachment of filter members, ensuring a fluid-tight seal and efficient filtration process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a conventional filter assembly uses a basket member to house and secure the filter bag, then the filter bag can be contained and positioned, but the filter bag is difficult to secure and unsecure during operations

Engineering Contradiction:
Improveease of securing and unsecuring filter bagVSAvoidcomplexity of locking mechanism
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The locking assembly is divided into separate functional components: a locking member with cam surface, securing members (clamps or clips) with release mechanisms, and a basket member with engagement features. This segmentation allows each component to perform its specific function efficiently while enabling easy operation through simple actuation of the release mechanism.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The locking mechanism incorporates movable securing members that can transition between locked and unlocked positions. The cam surface on the locking member provides a mechanical advantage that allows quick engagement and disengagement of the securing members, transforming a static basket into a dynamic locking system that responds to operator input.

Inventive Principle:
Principle #15Dynamics

2Reliability

If the filter assembly uses a simple basket member without locking mechanism, then the device complexity is reduced, but the filter bag cannot be securely held in position

Engineering Contradiction:
Improvesecurity of filter bag attachmentVSAvoidcomplexity of locking assembly
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The securing members are pre-configured with release mechanisms that are activated by the locking member. The cam surface is pre-positioned to engage with the securing members, so that when the locking member is actuated, the securing members automatically move to the locked or unlocked position without requiring additional manual manipulation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The locking member acts as an intermediary between the operator and the securing members. By providing a cam surface that interacts with the securing members, the locking member translates simple operator input into reliable locking or unlocking action, ensuring secure attachment while maintaining operational simplicity.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If the filter assembly uses multiple securing mechanisms to ensure reliable filtration, then the filtration reliability is improved, but the time required for securing and unsecuring the filter bag increases

Engineering Contradiction:
Improvereliability of fluid-tight sealVSAvoidtime for securing and unsecuring filter bag
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

Multiple securing members (clamps or clips) are combined with a single locking member that controls all of them simultaneously. The cam surface on the locking member engages with all securing members at once, allowing them to be locked or unlocked in a single coordinated action. This merging reduces the time required for securing and unsecuring while maintaining the reliability provided by multiple securing points.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The locking mechanism operates through periodic action: a single actuation of the locking member causes all securing members to move from locked to unlocked position (or vice versa) in a rapid, coordinated sequence. This periodic action eliminates the need for sequential manipulation of each securing member, significantly reducing the time required for filter bag changes.

Inventive Principle:
Principle #19Periodic action
