Solution Overview

Problem

Existing automatic cloth-vibrating and cake-removing devices are hindered by the fixed mounting of their main body on pull-plate trolleys, interfering with the normal operation of the automatic filter cloth cleaning mechanism, resulting in a lack of automatic cloth washing functionality and incompatibility between cloth vibration and washing.

Innovation Solution

The device is redesigned with a trailer-type pneumatic vibrating device that can be hung on and unhooked from pull-plate trolleys, incorporating cantilever type air cylinder platforms and elastic cloth-vibrating devices to allow simultaneous cloth vibration and washing, with a trailer type pneumatic vibrating device comprising movable trailer seats, gate-type frames, and cantilever type air cylinder platforms.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If the pneumatic vibrating device is fixedly mounted on pull-plate trolleys, then automatic cloth vibration and cake removal is achieved, but the automatic filter cloth cleaning mechanism is hindered from normal operation

Engineering Contradiction:
Improveautomatic cloth vibration and cake removalVSAvoidcloth washing mechanism operation
Core Design Contradiction:
Extent of automationVSEase of operation

Solution Approach 1:

The pneumatic vibrating device is transformed from a fixed mounting structure to a movable trailer-type structure that can dynamically adjust its position. The device can be hooked onto the pull-plate trolleys when cloth vibration is needed, and unhooked when the cleaning mechanism needs to operate, enabling dynamic adaptation between different operational modes.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The vibrating device is divided into independent functional modules including the trailer frame, pneumatic vibrating mechanism, and hooking/unhooking components. This segmentation allows the device to be independently controlled and positioned, enabling it to be detached from the pull-plate trolleys when the cleaning mechanism requires unobstructed access.

Inventive Principle:
Principle #1Segmentation

2Productivity

If the pneumatic vibrating device is fixedly mounted on pull-plate trolleys, then automatic cake removal is achieved, but automatic cloth washing functionality is lost

Engineering Contradiction:
Improveautomatic cake removal efficiencyVSAvoidcloth washing capability
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The trailer-type pneumatic vibrating device is designed with universal hooking and unhooking capabilities, allowing it to be attached when cake removal is needed and detached when cloth washing is required. This multi-functional design enables the filter press system to perform both automatic cake removal and automatic cloth washing operations effectively.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Extent of automation

If the pneumatic vibrating device is fixedly mounted, then cloth vibration function is achieved, but compatibility with cloth washing mechanism is lost

Engineering Contradiction:
Improveautomatic cloth vibrationVSAvoidcompatibility with washing mechanism
Core Design Contradiction:
Extent of automationVSAdaptability or versatility

Solution Approach 1:

The trailer-type mounting structure enables the pneumatic vibrating device to dynamically transition between attached and detached states. When attached, it provides automatic cloth vibration for cake removal; when detached, it allows the cloth washing mechanism to operate without interference, achieving compatibility between the two functions.

Inventive Principle:
Principle #15Dynamics
