Drivable Drainage Device With Angle Profiles For Load Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drivable drainage devices face challenges with complex profile shapes leading to strength losses in load transfer and high production costs due to reentrant shoulders and non-positive clamp connections, as well as limited adjustability and drainage efficiency.
Innovation Solution
A drivable drainage device with a channel profile featuring vertical longitudinal walls and separate angle profiles that provide load transfer support via parallel wall legs, allowing for simple construction and effective drainage without reentrant shoulders, along with adjustable screw bolts for easy adjustment and drainage through-holes for enhanced seepage management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If reentrant shoulders are formed in the channel profile to support the cover grating, then the cover grating can be supported, but the profile shape becomes complex and strength is lost in load transfer
Solution Approach 1:
The support function is segmented from the channel profile by introducing separate angle profiles (Winket profiles) that are attached to the longitudinal walls. These angle profiles provide the reentrant shoulders needed to support the cover grating, while the channel profile itself maintains a simple rectangular cross-section optimized for load transfer.
Solution Approach 2:
The reentrant shoulders are extracted from the channel profile structure and implemented as separate angle profiles. This extraction allows the channel profile to be simplified while still providing the necessary support function through the attached angle profiles.
2Adaptability or versatility
If additional wall profiles with U-shaped cross section are added to adjust channel height, then height adjustability is achieved, but production cost increases and clamp connection is non-positive
Solution Approach 1:
The angle profiles are designed with adjustable components that allow the channel height to be modified after installation. The clamp connection enables dynamic adjustment of the angle profiles' position and orientation, providing versatility while maintaining a relatively simple manufacturing process.
3Reliability
If crossbars are used to connect cover grating to channel profile, then the cover grating can be secured, but the structure becomes more complex
Solution Approach 1:
The angle profiles serve multiple functions simultaneously: they provide the reentrant shoulders for cover grating support, act as connection elements between the channel profile and cover grating, and eliminate the need for separate crossbars. This merging of functions simplifies the overall connection structure while maintaining reliability.

Function Achieved in This Case
This solution ensures efficient load transfer and drainage while maintaining a simple profile shape, allowing for post-installation adjustments and improved seepage handling, reducing production costs and enhancing the overall performance of the drainage system.
Implementation Method 1
The wall legs of the angle profiles that are parallel to the wall only need to be welded to the longitudinal walls of the channel profile
Implementation Method 2
the wall limbs of the angle profiles can be provided with drainage holes, so that liquid can flow through the drainage holes in the wall limbs of the angle profiles into the channel profile

AI summary
The dewatering device has longitudinal walls (3) that are connected to a gutter bottom (2) to form gutter profile (1). A cover grating (9) is supported between longitudinal walls of the gutter profile. The bracket sections (10) are welded at the longitudinal walls of the gutter profile. A support leg (14) in bracket section is projected from wall leg (12) of gutter profile at predefined spacing above the gutter bottom to support cover grating.
