Sewage Pump Lid Access via Box Body Drain Holes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sewage and wastewater shredding and pumping apparatus with immersion engines face difficulties in maintenance due to clogging and obstruction, requiring the disconnection and removal of drainage pipes, leading to time-consuming and inconvenient processes.
Innovation Solution
The apparatus features a drain pipe system with drainage holes directly in the box body, allowing the lid to be removed without disconnecting drainage pipes, enabling easy access to internal components for maintenance without disassembling the unit from the WC.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If drainage pipes are connected to the lid for sewage discharge, then the drainage function is achieved, but the maintenance operation becomes complicated and time-consuming
Solution Approach 1:
The drainage function is segmented from the lid by providing separate drainage holes in the box body. This allows the lid to be independently removed for maintenance without affecting the drainage pipes, resolving the contradiction between ease of maintenance and device complexity.
Solution Approach 2:
The drainage holes are extracted from the lid and placed directly in the box body. This extraction eliminates the need for pipes passing through the lid, enabling simple lid removal for maintenance while preserving drainage functionality.
2Ease of repair
If the lid is removed for maintenance access, then internal components become accessible, but drainage pipes must be disconnected causing liquid leakage
Solution Approach 1:
The sealing function is segmented from the lid by providing gaskets at the interface between the lid and box body. This allows the lid to be removed for maintenance while the gasket prevents liquid leakage, resolving the contradiction between ease of repair and harmful effects.
Solution Approach 2:
Gaskets are installed beforehand at the lid-box interface to create a seal. This prior cushioning prevents liquid leakage when the lid is removed for maintenance, eliminating the harmful effect while maintaining ease of repair.
3Adaptability or versatility
If multiple pipes are connected to the lid, then drainage and delivery functions are integrated, but the overall device structure becomes more complex
Solution Approach 1:
The drainage and delivery functions are segmented into separate openings in the box body. This allows each function to be independently connected without requiring complex pipe arrangements on the lid, reducing device complexity while maintaining versatility.
Solution Approach 2:
The box body is designed with multiple openings that can serve different functions (drainage, delivery). This universal approach allows various pipe connections to be made directly on the box body without requiring a complex lid structure, achieving multi-functionality with simpler geometry.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design simplifies maintenance by allowing quick and easy access to internal components, reducing the risk of liquid leakage and saving time, as the lid can be removed without disconnecting external conduits, facilitating efficient maintenance operations.
Implementation Method 1
The operation of the engine makes, on the one hand, that the impeller creates a depression that carries the liquid contained in the box towards an external drainage

AI summary
The present invention concerns an apparatus (1) for the treatment of sewage coming from one or more external utilities and comprising: A box (2) for collecting sewage coming from said external utilities; A lid (3) for closing the box; An apparatus for the shredding/pumping (100) of the sewage arranged inside the box (2) so as to shred the sewage coming from at least one of said external utilities and push all the sewage carried in the box (2) towards the outside; A drain pipe (117, 17, 17', 17", 17'") connected to said apparatus (100) to drain towards the outside of the box (2) the sewage contained in it. In accordance with the invention the drain pipe (117,17, 17', 17", 17'") terminates outside through one or more drain holes (27, 25) directly found in the body of the box (2) so that the lid (3) results lacking any opening configured to connect one or more conduits for the drain of sewage or the entry of sewage in the box.
