Solution Overview
Problem
Existing draining devices, such as pipes and ditches, face issues like poor draining efficiency, blockage, high costs due to secondary processing, and limited flexibility, especially when dealing with permeated water and rainwater.
Innovation Solution
A draining device with a permeable wall body comprising a plurality of ribs having a wavy cross-section, where the wave amplitude changes from one side to the other, providing alternating wave crest and trough parts, and connected in a spiral shape, allowing for elastic expansion and anti-blocking properties, made from plastic material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If secondary drilling is performed on impermeable walls to create draining holes, then draining efficiency is improved, but compression performance deteriorates and additional processing costs increase
Solution Approach 1:
The patent applies preliminary action by pre-forming through-holes during the extrusion molding process before the product is put into service. The draining holes are created during manufacturing rather than through secondary drilling after production, which prevents damage to the wall structure and avoids compromising compression performance while achieving the required draining efficiency
Solution Approach 2:
The patent changes the parameter of hole formation from post-manufacturing drilling to in-manufacturing extrusion. By adjusting the molding parameters and using a multi-opening mold during extrusion, the system creates through-holes with optimal size and distribution that maintain wall strength while enabling drainage functionality
2Productivity
If drilling rate is increased to improve draining effect, then draining efficiency is improved, but compression performance deteriorates
Solution Approach 1:
The patent optimizes the drilling rate parameter by integrating hole formation into the extrusion process. The through-holes are created with controlled distribution and size during molding, achieving high draining effect while maintaining wall integrity and compression performance that would be compromised by post-manufacturing drilling
3Strength
If pipe wall thickness is increased to improve compression performance, then structural strength is improved, but draining channel size decreases and draining effect deteriorates
Solution Approach 1:
The patent transforms the solid pipe wall into a porous structure with integrated through-holes. This creates dedicated draining channels within the wall thickness that provide effective drainage pathways while maintaining the overall wall strength through optimized hole distribution and size, resolving the trade-off between wall thickness, strength, and draining capability
4Stability of the object's composition
If rigid structures are used for draining devices, then structural stability is improved, but flexibility and ease of installation deteriorate
Solution Approach 1:
The patent employs a flexible hollow plastic pipe as the base structure, allowing the draining device to be bent and adapted to various installation configurations. The integrated through-holes and rib structures provide sufficient structural stability while the flexible material enables easy installation in different locations and orientations
5Productivity
If high drilling rate is applied to well box walls, then draining efficiency is improved, but compression performance and structural stability deteriorate
Solution Approach 1:
The patent applies preliminary action by forming through-holes in the well box walls during the extrusion molding process. This pre-forming approach creates drainage channels without compromising the structural stability of the well box, as the holes are integrated into the wall structure during manufacturing rather than being added through secondary drilling that would weaken the walls

AI summary
A draining device, which can discharge permeated water and/or rainwater quickly, and adapt to different construction requirements is provided. The draining device may have a permeable wall body. The permeable wall body may have a plurality of ribs, where a cross section of the ribs in a first direction is wavy, and a wave amplitude of the cross section gradually changes, from a first side to a second side, in a second direction. Therefore, the ribs have alternating wave crest parts and wave trough parts at either side of the first direction. The wave crest part of one rib, among two adjacent ribs is opposite to the wave trough part of the other. The first direction intersects the second direction. The second direction is a thickness direction of the permeable wall body.
