Cross Control Fitting Layout for Easier Concrete Line Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing concrete components using liquid concrete face difficulties in cleaning hard-to-reach regions of control fittings, requiring additional steps and tools for residual concrete ejection and intermediate cleaning processes.
Innovation Solution
A control fitting with a two-way cross design and a guide piece that allows the control member to move between open and closed positions, facilitating easier access for cleaning by retracting the control member and using a sponge ball for cleaning, reducing the need for additional assembly steps and ensuring continuous delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If hose lines are connected and reconnected to various nozzles for cleaning, then cleaning coverage is improved, but device complexity and time consumption increase
Solution Approach 1:
The control member is designed to retract automatically or be easily moved into a cleaning position that exposes hard-to-reach regions to cleaning media, allowing the system to clean itself without requiring external hoses or additional assembly steps
Solution Approach 2:
The control member transitions from a static position to a dynamic cleaning position, changing its spatial configuration to enable access for cleaning operations without requiring reconnection of external cleaning equipment
2Ease of operation
If additional ejection spindle and intermediate cleaning operations are performed, then residual concrete removal is improved, but productivity decreases
Solution Approach 1:
The control member is designed to facilitate preliminary cleaning access by retracting or repositioning before concrete ejection, preventing residual concrete accumulation and eliminating the need for additional intermediate cleaning operations
Solution Approach 2:
The design enables continuous concreting operations without interruption for cleaning, as the control member's retraction provides ongoing access for removing residual concrete during the concreting process itself
3Stability of the object's composition
If control member is fixed in guide piece, then structural stability is improved, but cleaning accessibility deteriorates
Solution Approach 1:
The control member transitions from a fixed position during operation to a retracted or repositioned state during cleaning, dynamically changing its location to provide access to the guide piece while maintaining structural stability during concreting
