Engine Side Rib Drainage Guide for Cooling Pump
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle engine designs for cooling water pumps require enlarged cover members to direct drainage, limiting flexibility and increasing complexity in the drainage discharge path.
Innovation Solution
The integration of engine side ribs and windshield ribs on the engine body and pump case allows for direct downward drainage without the need for additional cover members, creating a labyrinth structure that enhances drainage directionality and reduces air flow influence, while maintaining a compact design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cover members are used to direct drainage from the cooling water pump, then drainage can be discharged to a predetermined position, but the cover members are likely to be enlarged and their shapes are limited
Solution Approach 1:
The patent merges the drainage guiding function into the engine side rib structure that is already present on the engine body. The engine side rib is positioned to receive drainage from the cooling water pump and guide it downward, eliminating the need for separate cover members to perform this function. This integration reduces the number of components and avoids the enlargement of cover members while maintaining effective drainage discharge.
Solution Approach 2:
The engine side rib serves dual purposes: it provides structural support for mounting the cooling water pump and simultaneously functions as a drainage guide. By making the engine side rib itself responsible for directing the drainage, the system uses existing structures to perform additional functions, avoiding the need for enlarged or specialized cover members.
2Reliability
If a drainage discharge path is formed by cover members, then drainage can be led to a given position, but the flexibility of cover member shapes is reduced
Solution Approach 1:
The drainage guiding function is merged with the engine side rib structure, which is an integral part of the engine body. This allows the drainage path to be formed by the natural geometry and positioning of the engine side rib rather than requiring separate cover members with limited shape flexibility. The engine side rib can be designed with greater freedom in its geometric configuration to optimize drainage flow.
3Reliability
If cover members are enlarged to accommodate drainage discharge path, then drainage can be discharged, but the overall structure becomes more complex
Solution Approach 1:
The drainage guiding function is extracted from the cover members and transferred to the engine side rib structure. This separation allows the cover members to maintain their original, simpler forms while the engine side rib assumes the responsibility of directing drainage. The result is a reduction in overall structural complexity while maintaining effective drainage discharge functionality.
Solution Approach 2:
The drainage guiding function is combined with the existing engine side rib structure, eliminating the need for enlarged cover members. This integration simplifies the overall structure by using already-present components to perform multiple functions, thereby reducing device complexity while maintaining drainage discharge reliability.

AI summary
While enlargement of cover members attached to an engine body is avoided, the flexibility of the shapes of the cover members is increased and it is made possible to lead to a predetermined position drainage discharged from a cooling water pump attached to the external surface of a lateral wall of the engine body. A drainage discharge hole for discharging drainage is provided in a lower portion of a pump case. An engine side rib leads downward drainage discharged from the drainage discharge hole is integrally provided on an engine body forming part of the engine body so as to project from an external surface of a lateral surface thereof.
