Modular Gully Rib Structure and Connector Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Gullies experience integrity issues due to vibrations and pressures from heavy vehicles and heavy rains, leading to fracturing or blocking, and require adaptable filters and safe animal removal mechanisms while ensuring mechanical strength and water tightness.
Innovation Solution
A modular gully design with connector parts for easy orientation and assembly, incorporating a rib structure for improved water tightness and a filter system with modular parts for adjustable pore sizes, and an odor lock or aerator function.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a gully is designed with a solid non-modular structure to ensure mechanical strength and integrity, then resistance to vibrations and pressures from heavy vehicles improves, but adaptability for different situations and locations deteriorates
Solution Approach 1:
The gully is divided into multiple modular body parts (first body part, second body part, third body part) that can be stacked in different configurations. Each module maintains structural integrity through rib structures and connector parts, while the overall system achieves adaptability through modular assembly. This segmentation allows the same standardized modules to serve different drainage needs at various locations.
2Ease of manufacture
If a gully uses a fixed filter design to simplify structure, then manufacturing complexity reduces, but ability to adapt filter pore sizes for different locations deteriorates
Solution Approach 1:
The filter system is designed as a removable and replaceable component rather than a fixed structure. Filters with different pore sizes can be swapped depending on the specific drainage location requirements (e.g., larger pores in areas with more debris, smaller pores in cleaner areas). This dynamic configuration maintains manufacturing simplicity while achieving filter adaptability.
3Manufacturing precision
If connector parts are designed with complex orientation features to ensure correct assembly, then assembly accuracy improves, but device complexity increases
Solution Approach 1:
The connector parts incorporate asymmetric features such as protrusions and recesses that provide visual and physical orientation cues. These asymmetric elements guide workers to assemble modules in the correct orientation without requiring complex alignment mechanisms. The asymmetry is simple enough to maintain low device complexity while ensuring high assembly accuracy.
4Reliability
If a gully is designed as a single integrated piece to ensure water tightness, then sealing reliability improves, but ease of maintenance and cleaning deteriorates
Solution Approach 1:
The gully is segmented into multiple stackable body parts with connector parts that include sealing elements (such as gaskets or integrated seals). This segmentation maintains water tightness through the sealing connectors while enabling easy maintenance - workers can disassemble the modular sections to access and clean internal components, remove blockages, or replace filters without dealing with a monolithic structure.
