Dynamometer Cooling Pipe Interface Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dynamometer devices face increased pressure loss and a higher number of parts due to the use of long pipes connecting the dynamo body and tank in a vertical configuration, leading to inefficiencies and complexity.
Innovation Solution
A dynamometer device design where the pipe passes through the interface between the dynamo body and tank, with outlets opening inside the tank, allowing for a shorter pipe connection and reducing the need for additional parts, thereby minimizing pressure loss and simplifying assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a long pipe is used to connect the dynamo body and tank in vertical configuration, then the connection is structurally simple, but pressure loss increases and the number of parts increases
Solution Approach 1:
The patent transitions from a vertical configuration to a horizontal configuration where the pipe passes through the interface between the dynamo body and tank. This dimensional change allows the pipe to be shorter while maintaining functional connectivity, thereby reducing pressure loss and minimizing the number of required parts.
2Ease of manufacture
If a long pipe is used for connecting the dynamo body and tank, then connection flexibility is maintained, but assembly steps increase and device compactness decreases
Solution Approach 1:
The patent merges the pipe connection with the interface structure between the dynamo body and tank. The pipe passes directly through the interface, integrating the connection function into the existing structural boundary. This eliminates the need for separate connection parts and reduces assembly steps while achieving a more compact device configuration.

AI summary
In a dynamometer device (1), a dynamometer (5) is placed on a dynamometer-side bed (6), and the dynamometer-side bed (6) is stacked on a tank-side bed (15) located on the top part of a bed tank (3). The dynamometer (5) is connected to the bed tank (3) by an oil discharge pipe (9) which returns a cooling oil (2) to the bed tank (3) from the dynamometer (5). The oil discharge pipe (9) passes through an interface (23) between the dynamometer-side bed (6) and the tank-side bed (15), and extends into the bed tank (3).
