Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle suspension systems require additional bracket assemblies or weldments for installing jounce bumpers, complicating the installation process and reducing efficiency.
Innovation Solution
A damping assembly that includes a spring, a hydraulic jounce bumper, and a reinforcement member integrated with a spring isolator, allowing for easy installation without additional brackets or weldments, with the reinforcement member securing the hydraulic jounce bumper and distributing jounce forces effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional bracket assemblies or weldments are used for installing jounce bumpers, then the jounce bumper can be securely installed, but the installation process becomes complicated and production time increases
Solution Approach 1:
The reinforcement member is integrated directly into the spring isolator structure, combining two separate components (spring isolator and reinforcement member) into a single unified component. This eliminates the need for additional bracket assemblies or weldments, simplifying the installation process while maintaining secure installation of the jounce bumper.
2Reliability
If additional bracket assemblies or weldments are used for installing jounce bumpers, then the jounce bumper can be securely installed, but production time and parts quantity increase
Solution Approach 1:
The reinforcement member is integrated directly into the spring isolator structure, combining two separate components (spring isolator and reinforcement member) into a single unified component. This reduces the total number of parts needed and simplifies the installation process, thereby improving production efficiency while maintaining secure installation of the jounce bumper.
3Productivity
If a reinforcement member is integrated with the spring isolator, then installation is simplified and production efficiency improves, but the structural complexity of the damping assembly increases
Solution Approach 1:
The reinforcement member is integrated directly into the spring isolator structure, combining two separate components (spring isolator and reinforcement member) into a single unified component. This integration simplifies installation and improves manufacturing efficiency while the internal reinforcement structure provides the necessary structural support within the unified component.
Solution Approach 2:
The spring isolator incorporates a reinforcement member within its structure, creating a composite component that combines the isolating properties of the spring isolator material with the structural strength of the reinforcement member. This composite structure maintains simplicity from an installation perspective while providing enhanced structural capability.

AI summary
A damping assembly for a vehicle suspension system may include a spring including a first end operably coupled to a body of a vehicle and a second end operably coupled to a wheel assembly of the vehicle, a spring isolator operably coupling the body of the vehicle to the first end of the spring, a hydraulic jounce bumper to dampen jounce forces on the vehicle, and a reinforcement member operably coupled to the hydraulic jounce bumper at a proximal end of the reinforcement member and to the spring isolator at a distal end of the reinforcement member. The reinforcement member may be integrated with the spring isolator at the distal end of the reinforcement member.
