Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for securing nuts to aluminum U-shaped structural members in vehicles, such as welding and pull riveting, face challenges like high holing precision requirements and the need for specialized tools, which complicate the mounting process and can result in nut displacement or rotation during bolt installation.
Innovation Solution
A pre-assembly member with a base portion and clamping portion, featuring a hole, bending edges, and elastic clamping tails, securely mounts a nut to a U-shaped structural member, preventing rotation and allowing for easy alignment and secure fastening with reduced manufacturing tolerance requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If welding or pull riveting methods are used to secure nuts to aluminum U-shaped structural members, then the nuts can be attached to the structural member, but high holing precision requirements and specialized tools are needed, complicating the mounting process and potentially causing nut displacement or rotation during bolt installation
Solution Approach 1:
The patent introduces a pre-assembly member as an intermediary component between the nut and the U-shaped structural member. This pre-assembly member includes a base portion with a hole that receives the nut, and a clamping portion that secures the pre-assembly member to the structural member. By using this intermediary, the system eliminates the need for high holing precision in the structural member itself, as the pre-assembly member provides the precise mounting interface for the nut.
Solution Approach 2:
The patent divides the mounting function into two separate components: the pre-assembly member and the U-shaped structural member. The pre-assembly member is designed with specific geometric features (base portion with hole, clamping portion) that handle the nut mounting function, while the structural member maintains its primary structural function. This segmentation allows each component to be optimized independently, reducing the precision requirements for the structural member.
2Ease of manufacture
If welding or pull riveting methods are used to secure nuts to aluminum U-shaped structural members, then the nuts can be attached to the structural member, but specialized tools are required, which complicates the mounting process
Solution Approach 1:
The pre-assembly member serves as a mediator that simplifies the mounting process. Instead of requiring specialized welding equipment or pull riveting tools, the pre-assembly member can be attached using simpler fastening methods. The clamping portion of the pre-assembly member is designed to be secured to the U-shaped structural member through straightforward mounting operations, eliminating the need for complex specialized tools.
3Reliability
If conventional mounting methods are used, then nuts can be attached to the U-shaped structural member, but nut displacement or rotation can occur during bolt installation
Solution Approach 1:
The patent implements preliminary action by pre-assembling the nut onto the pre-assembly member before mounting it to the U-shaped structural member. The pre-assembly member is designed with a base portion that receives and secures the nut in a precise position. This preliminary assembly ensures that the nut is properly positioned and secured before the final mounting step, preventing any displacement or rotation during subsequent bolt installation operations.
Solution Approach 2:
The pre-assembly member acts as an intermediary that provides a stable mounting interface for the nut. The base portion with the hole is designed to securely hold the nut, while the clamping portion provides a stable connection to the structural member. This intermediary structure prevents nut displacement or rotation by distributing forces and providing a rigid mounting interface, thereby improving both reliability and ease of operation during bolt installation.

Function Achieved in This Case
The pre-assembly member simplifies the nut mounting process, reduces manufacturing costs, and ensures secure fastening by compensating for manufacturing tolerances and preventing nut rotation, thus enhancing the convenience and efficiency of bolt installation.
Implementation Method 1
a clamping portion, wherein the clamping portion is formed by bending and extending upward from a rear portion of the base portion, and the clamping portion is configured to secure the pre-assembly member to the U-shaped structural member
Data Source
AI summary
The present disclosure relates to the technical field of vehicle components, and in particular, to a pre-assembly member for securing a vehicle nut to a U-shaped structural member. The pre-assembly member includes: a base portion; and a clamping portion.
