Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge lies in efficiently and effectively attaching large and heavy vehicle suspensions to vehicle frames, as existing methods are labor-intensive and awkward due to the size and weight of the suspensions, requiring improvements for easier alignment and securement.
Innovation Solution
An interface device and method are introduced that utilize various configurations of connector sets, including hanger brackets and frame interface devices, to securely attach suspensions to vehicle frames, allowing for alignment and attachment using lighter and more manageable components, such as the interface device, which can be attached to the frame or suspension, simplifying the process and providing flexibility for different suspension types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the suspension is directly attached to the vehicle frame, then the attachment is secure, but the process is labor-intensive and difficult due to the size and weight of the suspension
Solution Approach 1:
The patent introduces a frame interface device as an intermediary component between the suspension and the vehicle frame. This device has a first interface that connects to the suspension and a second interface that connects to the frame, effectively mediating the attachment process. The frame interface device breaks down the complex task of attaching heavy suspension directly to the frame into simpler, more manageable steps, reducing labor intensity and improving ease of operation while maintaining secure attachment.
Solution Approach 2:
The attachment system is segmented into multiple independent components: the suspension, the frame interface device, and the vehicle frame. The frame interface device itself can be further segmented into different interface configurations (first interface and second interface). This segmentation allows each component to be optimized independently and makes the overall attachment process more manageable and less complex.
2Productivity
If the suspension is maneuvered into alignment with the frame, then secure attachment is possible, but the process becomes awkward and time-consuming
Solution Approach 1:
The frame interface device serves as a mediator that simplifies the alignment process. By providing standardized interfaces with specific geometric configurations, it guides the suspension into proper alignment with the frame during the connection process, reducing the manual maneuvering and adjustment required. This improves both productivity and ease of operation.
Solution Approach 2:
The frame interface device can be pre-installed on the vehicle frame with alignment features already in place. This preliminary action prepares the attachment location in advance, so that when the suspension arrives, the alignment process is simplified and faster, improving productivity without sacrificing ease of operation.
3Ease of operation
If traditional direct attachment methods are used, then structural integrity is maintained, but labor requirements and time increase
Solution Approach 1:
By segmenting the attachment system into modular components (suspension, frame interface device, frame), the patent enables parallel preparation and pre-positioning of components. This reduces the actual attachment time on the assembly line while maintaining structural integrity through properly designed connection interfaces. The modular approach simplifies the operation and reduces the time penalty.
4Reliability
If the suspension is held in place during securing, then proper alignment is achieved, but additional positioning mechanisms are required
Solution Approach 1:
The frame interface device acts as a stable intermediary that provides a fixed reference point during the attachment process. Its rigid connection to the frame and standardized interface geometry ensure proper positioning of the suspension without requiring complex active positioning mechanisms. The interface design itself incorporates alignment features that guide correct positioning, maintaining reliability while avoiding additional complexity.

AI summary
A method for securing a suspension may include attaching a frame interface device to a vehicle frame and aligning a first connector set. Two first connectors may straddle a second connector, or a first connector may be straddled by two second connectors, when the connector set is aligned. These aligned connectors may be secured by a fastener, thereby securing the suspension to the frame. A suspension attachment system may include a hanger bracket of a suspension, a frame interface device, and a connector set. Two first connectors may straddle a second connector when the connector set is aligned. The suspension may be secured to the frame as a result of the aligned and secured connector set.
