Vehicle Grab Handle Single Bracket Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing grab handles for vehicle passenger compartments are time-consuming and costly to manufacture and install, and may not provide a sturdy mounting system for easy passenger entry and exit.
Innovation Solution
A grab handle with a single mounting bracket featuring an L-shaped cross section, including an attachment portion with apertures and an abutment flange for easy alignment and mounting to the vehicle body, and a retaining portion with orthogonal design for securing a grip body, made from a single piece of sheet metal for cost-effective manufacturing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a traditional multi-part mounting bracket is used, then the structural strength may be sufficient, but the manufacturing and installation time and cost increase
Solution Approach 1:
The patent combines multiple separate mounting bracket components into a single integrated mounting bracket that includes both the attachment portion for securing to the vehicle body and the retaining portion for holding the grip body. This merging of functions reduces the number of parts, simplifies manufacturing, and accelerates installation while maintaining structural strength.
2Manufacturing precision
If a complex alignment system is used, then the mounting precision may be improved, but the installation time and complexity increase
Solution Approach 1:
The mounting bracket is designed with an abutment flange that extends substantially orthogonal to the attachment portion, forming an L-shaped cross section. This preliminary structural design built into the single-piece bracket enables automatic alignment with the vehicle body member during installation, eliminating the need for complex alignment systems or procedures and significantly reducing installation time.
3Ease of manufacture
If a single-piece mounting bracket is used, then the manufacturing cost and time decrease, but the structural strength may be compromised
Solution Approach 1:
The mounting bracket is formed as a single piece from sheet metal, utilizing the material's inherent strength properties. The L-shaped cross section design with the abutment flange extending orthogonal to the attachment portion creates a structurally robust configuration that can handle forceful tugs and pulls while maintaining ease of manufacture from a single material piece.
4Reliability
If multiple separate components are used, then the structural integrity may be maintained, but the installation complexity and time increase
Solution Approach 1:
The patent integrates the attachment portion and retaining portion into a single mounting bracket component, reducing the number of parts that need to be assembled while maintaining structural integrity. The single-piece construction eliminates joints or connections between multiple components, thereby maintaining reliability while simplifying the overall device structure and installation process.
