Pedal Unit Coupling Assembly for Fluid Line Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing pedal units for vehicles require a time-consuming and complex installation process due to the need for multiple separate coupling devices, leading to increased risks of installation errors and higher costs associated with design modifications.
Innovation Solution
A pedal unit with a single coupling assembly that includes internal passageways and gaskets to establish fluid communication between multiple fluid lines and ports, simplifying the installation process and reducing the risk of errors through a sealed connection using gaskets and a clamping ring, and ensuring proper alignment with recesses and asymmetric through-holes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate coupling devices are used to connect fluid lines to inlet ports or outlet ports, then each connection can be established individually, but the installation process becomes time-consuming and complex
Solution Approach 1:
The patent combines multiple separate coupling devices into a single integrated coupling assembly that can connect multiple fluid lines simultaneously. The coupling assembly includes a body with multiple coupling elements arranged in a circular pattern, allowing multiple fluid lines to be connected in one operation rather than requiring multiple separate coupling devices to be mounted individually to the main body.
2Adaptability or versatility
If multiple separate coupling devices are mounted to the main body, then multiple fluid communication lines can be established, but the risk of installation errors increases
Solution Approach 1:
The patent combines multiple separate coupling devices into a single integrated coupling assembly that can connect multiple fluid lines simultaneously. The coupling assembly includes a body with multiple coupling elements arranged in a circular pattern, allowing multiple fluid lines to be connected in one operation rather than requiring multiple separate coupling devices to be mounted individually to the main body.
Solution Approach 2:
The coupling assembly incorporates asymmetric features including a non-circular clamping ring with flat sides that must align with corresponding flat surfaces on the main body, and asymmetric through-holes for mounting. These asymmetric features ensure correct orientation and positioning of the coupling assembly during installation, preventing incorrect assembly and reducing installation errors.
3Adaptability or versatility
If multiple coupling devices are used, then multiple connections can be made, but quality control and leakage testing become more time-consuming
Solution Approach 1:
The patent combines multiple separate coupling devices into a single integrated coupling assembly that can connect multiple fluid lines simultaneously. The coupling assembly includes a body with multiple coupling elements arranged in a circular pattern, allowing multiple fluid lines to be connected in one operation rather than requiring multiple separate coupling devices to be mounted individually to the main body.
4Adaptability or versatility
If the design of the main body is modified, then improved performance can be achieved, but all coupling devices must be modified as well
Solution Approach 1:
The patent segments the coupling function from the main body by using a detachable coupling assembly that can be separated from the main body. The coupling assembly is mounted to the main body through recesses and can be removed and replaced independently. This allows modifications to the main body design without requiring modifications to the coupling devices, as the coupling assembly can be independently designed and manufactured.
