Jack Bracket Mechanical Clamping and Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing car jack brackets for vehicles are not sufficiently strong and durable for attachment to the vehicle floor, as the anti-corrosion treatment on the floor prevents reliable adhesion, leading to potential displacement and moisture penetration during use.
Innovation Solution
A jack bracket with a centering pin and multi-part extension that includes a conical peripheral collar and pawl body for precise positioning and locking into the vehicle floor hole, combined with a clamping screw for secure attachment and flexible sealing ribs for reliable sealing, ensuring firm connection and sealing across different vehicle types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If adhesive film is used between the support surface and the vehicle floor, then the bracket can be attached to the vehicle floor, but the anti-corrosion treatment using wax prevents reliable adhesive attachment
Solution Approach 1:
The patent replaces the chemical adhesive attachment system with a mechanical attachment system. The bracket includes a support surface with a recess that receives the vehicle floor, and a clamping element that mechanically secures the bracket to the floor by clamping the support surface against the floor. This mechanical clamping mechanism overcomes the problem of adhesive failure on wax-treated surfaces.
Solution Approach 2:
The patent introduces an intermediary mechanical clamping element that acts between the bracket and the vehicle floor. This clamping element provides a reliable connection mechanism that does not depend on the chemical properties of the floor surface, thereby mediating the attachment problem caused by the anti-corrosion wax treatment.
2Ease of manufacture
If the bracket is attached using adhesive film, then the bracket can be mounted on the vehicle floor, but the attachment is not sufficiently strong and durable, leading to displacement during use
Solution Approach 1:
The patent replaces the weak adhesive bonding system with a strong mechanical clamping system. The clamping element applies continuous mechanical pressure to secure the bracket firmly to the vehicle floor, preventing displacement during use while maintaining ease of installation through the simple insertion and clamping mechanism.
3Ease of manufacture
If the bracket uses a simple attachment design, then the bracket can be produced simply, but the attachment is not firm enough to prevent moisture penetration
Solution Approach 1:
The patent segments the attachment function into multiple components: a support surface with recess, a clamping element, and a sealing element. This segmentation allows each component to perform its specific function effectively - the recess provides structural support, the clamping element provides firm attachment, and the sealing element prevents moisture penetration, while the overall design remains simple to manufacture.
Solution Approach 2:
The patent introduces a sealing element as an intermediary component between the bracket and the vehicle floor. This sealing element specifically addresses the moisture penetration problem by creating a barrier, while the simple clamping mechanism maintains production simplicity.
4Adaptability or versatility
If the bracket is designed to accommodate different vehicle types, then the bracket can be universally applied, but the attachment must work with varying floor thicknesses
Solution Approach 1:
The patent incorporates a dynamically adjustable clamping element that can adapt to different floor thicknesses. The clamping element can be adjusted in position or force to accommodate varying distances between the support surface and the vehicle floor, providing universality across different vehicle types without requiring complex specialized mechanisms for each vehicle type.

AI summary
The jack bracket has an extension (9) with an inside formed in single piece as central body at the console body and has a bolt body (8) connected outside of the extension resting at the wall hole (6). The bolt body is connected with the central body by a central tightening screw (15). The bolt body has a head unit (10) standing in engagement with the tightening screw.
