Jack Holder Self-Latching Structure for Fast Vehicle Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing jack holder installation methods on motor vehicles are complex and require additional fastening means like screws, rivets, or expansion pins, making the process cumbersome and time-consuming.
Innovation Solution
A jack holder design featuring elastically resilient latching elements that automatically spring back to form a locking mechanism upon installation, eliminating the need for additional fastening means by deflecting into a cavity within the fastening section and securing to the receptacle structure without external force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional fastening methods (screws, rivets, expansion pins) are used to attach the jack holder to the body, then the attachment strength and reliability are improved, but the device complexity and installation difficulty increase
Solution Approach 1:
The patent merges the fastening function directly into the jack holder body by integrating elastically resilient latching elements into the fastening section. This eliminates the need for separate fastening components like screws, rivets, or expansion pins, thereby reducing device complexity while maintaining secure attachment through the self-contained latching mechanism.
Solution Approach 2:
The latching elements are designed to automatically engage with the receptacle structure through elastic deformation and spring-back action during insertion. This self-service mechanism eliminates the need for additional manual fastening operations or external fastening tools, simplifying the installation process while ensuring reliable attachment.
2Reliability
If traditional fastening methods (screws, rivets, expansion pins) are used to attach the jack holder to the body, then the attachment strength and reliability are improved, but the installation time and productivity decrease
Solution Approach 1:
The latching elements are pre-configured in the fastening section with elastic resilience built into their structure. During installation, the elastically resilient latching elements automatically deflect and engage with the receptacle structure through spring-back action, eliminating the need for separate fastening steps. This preliminary configuration enables rapid one-step installation while ensuring secure attachment.
Solution Approach 2:
The self-latching mechanism performs the fastening action automatically during insertion without requiring manual intervention for fastening operations. The elastically resilient latching elements self-engage with the receptacle structure, dramatically reducing installation time and improving productivity while maintaining reliable attachment.
3Ease of operation
If elastically resilient latching elements are used to simplify installation, then the ease of operation and installation speed are improved, but the attachment strength may be compromised
Solution Approach 1:
The patent utilizes elastic resilience as a key parameter of the latching elements, allowing them to deflect during insertion and then spring back to engage securely with the receptacle structure. This parameter change enables the latching elements to generate sufficient engagement force for reliable attachment while maintaining simple installation operation.
Solution Approach 2:
The fastening section is designed as a composite structure integrating the main body with elastically resilient latching elements. This composite design combines the structural integrity of the main body with the elastic deformation capability of the latching elements, ensuring both easy installation and strong attachment strength.

AI summary
A jack holder, including a base body and a fastening section projecting therefrom. The fastening section for fastening the jack holder is insertable along its longitudinal direction into a receptacle section of a body-fixed receptacle structure of a motor vehicle. The fastening section has at least one latching element which, with respect to an installation position in which the jack holder is fastened to the receptacle structure, interacts in a locking manner with the receptacle section to secure this fastening. At least one latching element is designed to be elastically resilient and/or is fastened to a main body of the fastening section in such an elastically resilient manner such that when the fastening section is inserted into the receptacle section, it elastically deflects and automatically springs back when the installation position is reached to form the locking mechanism.
