Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for securing additional devices, such as child seats, within a motor vehicle's interior fail to provide a secure and temporary fastening mechanism that ensures stability during driving and braking.
Innovation Solution
A bracket with a bent bar structure, featuring end sections, arcuate sections, and a central section, which can be fastened to the vehicle's bodyshell structure, allowing for secure attachment of additional devices like child seats through a combination of direct and indirect connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rigid fastening system is used to secure additional devices during driving and braking, then stability and safety are improved, but the device complexity and installation difficulty increase
Solution Approach 1:
The bracket is divided into multiple individual sections (end sections, arcuate sections, central section) that are connected via bending points. This segmentation allows the bracket to be fastened at multiple discrete locations on the bodyshell structure, providing stable support while keeping each individual section simple in design and easy to manufacture.
Solution Approach 2:
The bracket transitions from a two-dimensional planar structure to a three-dimensional spatial structure by bending the bar at multiple points to form arcuate sections that extend in different directions. This dimensional change allows the bracket to engage with the bodyshell structure at multiple points in space, enhancing stability without increasing the complexity of individual components.
2Reliability
If a bent bar structure with multiple sections is used to provide stable fastening, then the fastening reliability is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The bent bar is segmented into standardizable individual sections (end sections, arcuate sections, central section) with defined geometric relationships. This segmentation allows each section to be manufactured and measured independently, reducing the cumulative precision requirements compared to a single complex bent bar, while still achieving high fastening reliability through the coordinated arrangement of sections.
3Adaptability or versatility
If a bracket structure with arcuate sections is used to accommodate different fastening positions, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The bracket design with multiple arcuate sections and bending points creates a universal fastening structure that can accommodate various fastening positions and orientations on the bodyshell structure. The same bracket configuration can adapt to different installation locations without requiring multiple specialized bracket designs, reducing overall system complexity while enhancing adaptability.

AI summary
A bracket (2) is provided for fastening to a bodyshell structure (6) of a motor vehicle. The bracket (2) is a bar that is bent to define first and second end sections (10, 28), first and second arcuate sections (11, 19) and a central section (18). The first end section (10) merges into the first arcuate section (11), the first arcuate section (11) merges into the central section (18), the central section (18) merges into the second arcuate section (19), and the second arcuate section (19) merges into a second end section (28). The end sections (10, 28) are parallel, and the central section (18) is perpendicular to the end sections (10, 28). Each arcuate section (11, 19) has plural partially arcuate sections (12, 14, 16, 20, 22, 24, 26), including one that is parallel to the central section (18).
