Solution Overview

Problem

Existing pendulum supporting devices in filter press apparatuses suffer from unreliable pendulum motion, abnormal sliding, and skew orientation, leading to wear, misalignment, and increased maintenance, which affects the efficiency and durability of the filtration process.

Innovation Solution

A pendulum supporting device with a carriage block member rigidly mounted to inner and outer carriage block holding members, featuring an engagement portion for a drive member, and replaceable sliding elements that distribute force evenly, allowing stable pendulum motion and minimizing wear on bearing elements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a prior art pendulum supporting device is coupled to a drive member via an engagement portion, then the filter plate member can be moved, but the device suffers from abnormal sliding and skew orientation leading to wear and misalignment

Engineering Contradiction:

Improvereliable pendulum motionVSAvoidabnormal sliding and skew orientation

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The pendulum supporting device is segmented into multiple functional components: a carriage block member with sliding elements for guiding motion, an inner carriage block holding member for pivotable connection, and an outer carriage block holding member for rigid engagement with the drive member. This segmentation allows each component to perform its specific function optimally, preventing abnormal sliding and skew orientation.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different parts of the device have specialized properties: the carriage block member features replaceable sliding elements for low-friction guiding, the inner holding member provides pivotable connection with proper clearance, and the outer holding member ensures rigid engagement. Each local region is optimized for its specific function, eliminating uniform wear and misalignment issues.

Inventive Principle:

Principle #3Local quality

2Adaptability or versatility

If the pendulum supporting device allows pendulum motion of the filter plate member, then the un-loading position can be achieved, but wear and misalignment increase during operation

Engineering Contradiction:

Improvependulum motion capabilityVSAvoidservice life of sliding elements

Core Design Contradiction:

Adaptability or versatilityVSDuration of action of stationary object

Solution Approach 1:

The sliding elements are designed to be replaceable, allowing the operator to easily replace worn elements without replacing the entire carriage block member. This self-service feature extends the overall service life of the device by enabling maintenance of only the consumable sliding elements while retaining the durable structural components.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The device incorporates both dynamic elements (pivotable inner holding member enabling pendulum motion) and static elements (rigid outer holding member providing stable engagement). This dynamic-static combination allows the filter plate member to achieve the necessary un-loading position through pendulum motion while maintaining proper alignment and reducing wear through controlled guiding.

Inventive Principle:

Principle #15Dynamics

3Force

If the carriage block member is rigidly mounted to holding members, then force transmission is improved, but the complexity of assembly and maintenance increases

Engineering Contradiction:

Improveforce transmission from drive memberVSAvoidassembly and maintenance complexity

Core Design Contradiction:

ForceVSEase of manufacture

Solution Approach 1:

The rigid force transmission path is segmented into modular components: the carriage block member rigidly connected to the outer holding member, which is separately assembled to the inner holding member. This segmentation maintains strong force transmission while enabling independent assembly and maintenance of each module, reducing overall complexity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The inner carriage block holding member acts as an intermediary between the rigid force transmission path (outer holding member) and the pivotable connection to the filter plate fitting member. This intermediary component transmits forces effectively while accommodating the necessary motion, simplifying the overall assembly structure.

Inventive Principle:

Principle #24Intermediary (Mediator)
