Solution Overview

Problem

The manual assembly and disassembly of heavy and bulky carding elements, such as false bottoms, in carding machines are labor-intensive and time-consuming, limiting access and maintenance efficiency due to their significant weight and size.

Innovation Solution

A mobile maintenance carriage with height-adjustable carrying means, including articulated support arms and pneumatic actuators, allows for easy lifting and positioning of card elements, facilitating their assembly and disassembly without the need for manual handling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual handling methods are used for false bottom assembly/disassembly, then equipment complexity remains low, but labor intensity and time consumption increase significantly

Engineering Contradiction:
Improveease of false bottom assemblyVSAvoidtime for maintenance operations
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

A mobile carriage equipped with carrying means serves as an intermediary device between the false bottom and the operator. The carriage includes a carrying platform that receives the false bottom, articulated support arms that provide mechanical assistance for positioning, and height adjustment mechanisms that adapt to different maintenance positions. This intermediary system eliminates the need for direct manual handling of the heavy false bottom while maintaining operational simplicity.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If the false bottom is made fully removable for easy maintenance access, then ease of operation improves, but the structural complexity of the mounting system increases

Engineering Contradiction:
Improveaccess to cylinder for maintenanceVSAvoidcomplexity of mounting system
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The mounting system incorporates dynamic elements including a mobile carriage that can be repositioned along the card frame, height-adjustable carrying means with articulated support arms, and movable fixing mechanisms. These dynamic components allow the false bottom to be easily removed and reinstalled at different positions and orientations, providing full maintenance access without requiring a complex fixed mounting structure.

Inventive Principle:
Principle #15Dynamics

3Area of stationary object

If heavy false bottoms are designed with larger working width to cover more cylinder surface, then protective function improves, but handling difficulty increases

Engineering Contradiction:
Improvecoverage area of false bottomVSAvoidhandling ease during assembly
Core Design Contradiction:
Area of stationary objectVSEase of operation

Solution Approach 1:

The mobile carriage with its carrying platform and articulated support arms acts as a mediator that distributes the handling load. The carrying platform supports the entire weight of the large-area false bottom, while the articulated support arms provide mechanical leverage for positioning. This intermediary system enables operators to handle oversized false bottoms that would otherwise be impossible to maneuver manually.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The mounting system introduces vertical dimension through height-adjustable carrying means and articulated support arms with multiple degrees of freedom. This allows the false bottom to be positioned at optimal heights for assembly and disassembly, reducing the physical effort required to handle large-area components by eliminating the need for awkward low-position manual lifting.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

The machine has a card component e.g. false floor, mounting and dismounting system (2) comprising a moving carriage (20) which is mounted on two parallel guide rails (21). The guide rails permit to guide the carriage in translation with respect to the ground and are positioned under cylinders of the card e.g. cotton card. The carriages comprise castors (201) and rests on the guide rails by utilizing the castors. The system has a carrier unit (22) which is adjustable in height and supports the card component.
