Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hydraulic pressure relief mechanisms in high-performance vehicle torque converters require labor-intensive and time-consuming adjustments of output valves to optimize performance, which is unsafe and inefficient due to the need for frequent exchanges and sensitivity to environmental and track conditions.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If prior art output valves are exchanged to adjust opening size, then torque converter performance can be optimized, but the adjustment process becomes labor-intensive and time-consuming
Solution Approach 1:
The valve body is designed with multiple openings of different sizes that can be selectively positioned into the fluid flow path. The mechanism allows dynamic selection of opening sizes by rotating the valve body to different angular positions, enabling quick adjustment of fluid flow characteristics without exchanging valve components. This resolves the contradiction by providing performance adaptability through positional variation rather than physical component exchange.
Solution Approach 2:
The valve body is segmented into multiple functional openings (first opening, second opening, third opening) with different sizes and positions. Each opening represents a discrete flow configuration option. By segmenting the flow control function into multiple selectable openings within a single valve body, the system enables performance optimization through selection rather than exchange, significantly reducing adjustment time.
2Adaptability or versatility
If prior art output valves are exchanged to optimize performance, then fluid flow can be adjusted, but the process requires removal and installation of parts which is unsafe and inefficient
Solution Approach 1:
The valve mechanism allows dynamic adjustment of fluid flow by rotating the valve body to different angular positions, selecting among multiple pre-configured openings. This dynamic repositioning eliminates the need for removal and installation operations, making the adjustment process safer and more efficient while maintaining full fluid flow adjustment capability.
Solution Approach 2:
A single valve body incorporates multiple openings of different sizes and positions, making it a multi-functional component that can provide various flow adjustment modes. This universal design eliminates the need for multiple separate valves or exchange operations, allowing all fluid flow adjustments to be made by one component through positional variation, thereby improving operational safety and efficiency.
3Manufacturing precision
If tight tolerances are maintained for torque converter pressure control, then optimal performance is achieved, but the system becomes sensitive to environmental and track condition changes
Solution Approach 1:
The system provides dynamic pressure control by allowing selection among multiple opening sizes and positions within the valve body. When environmental or track conditions change, the operator can rotate the valve to select a different opening configuration that compensates for the changes, maintaining optimal performance without being constrained by fixed tight tolerances. This dynamic adaptability resolves the contradiction between precision and environmental sensitivity.
Solution Approach 2:
The valve mechanism enables changes in fluid flow parameters by selecting among multiple pre-designed opening configurations. Each opening represents a different flow parameter setting. By allowing parameter selection rather than requiring precise manufacturing tolerances, the system becomes adaptable to varying environmental and track conditions while maintaining effective pressure control.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution enhances safety and reduces labor and time spent on optimizing torque converter performance by allowing rapid adjustment of fluid flow without exchanging parts, improving stall speed and overall engine performance.
Implementation Method 1
The pressure relief mechanism includes a solenoid and one or more prior art output valves. The solenoid acts to selectively block fluid flow through the prior art output valves.
Implementation Method 2
The engine of the vehicle is mechanically connected to the impeller of the torque converter. Power from the engine turns the impeller, which moves the hydraulic fluid within the torque converter toward the turbine, generating fluid pressure.
Implementation Method 3
The pressure relief mechanism is typically attached to the housing of the transmission and assists in pressure modulation of the torque converter by providing selective fluid communication between a turbine-side of the torque converter and the rest of the transmission.
