Sheet Metal Fixing Bracket for Engine Anchoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anchoring systems for securing components to rigid elements in internal combustion engines are either heavy and costly due to casting techniques or lack rigidity when using stamped angle bracket supports.
Innovation Solution
A fixing anchor composed of bent and punched sheet metal parts, featuring a base with flanges for bolted joints and a compression part with cylindrical sectors, providing high rigidity and ease of manufacturing through welding or brazing, suitable for anchoring heavy components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If casting techniques are used to manufacture the anchor as an integral part of the component, then the anchor provides sufficient rigidity for heavy components, but the manufacturing cost increases and the anchor becomes heavier
Solution Approach 1:
The anchor is divided into two separate parts: a base part that is stamped from sheet metal and a compression part that is also stamped from sheet metal. These parts are then joined together through welding or brazing. This segmentation allows each part to be manufactured using cost-effective stamping processes rather than expensive casting, while the assembled structure maintains the required rigidity for heavy component anchoring.
2Ease of manufacture
If stamped angle bracket support is used, then the manufacturing cost decreases and ease of manufacture improves, but the rigidity becomes insufficient for heavy components
Solution Approach 1:
The invention combines two stamped sheet metal parts (the base with flanges and the compression part with cylindrical sector) into a unified anchor structure through welding or brazing. This merging creates a rigid assembly that can effectively secure heavy components, overcoming the limitation of single-piece angle brackets while maintaining the cost advantages of stamped manufacturing.
3Ease of manufacture
If casting techniques are used, then the anchor can be manufactured as an integral part, but the manufacturing complexity increases due to through holes or cavities requiring cores and moving parts in molds
Solution Approach 1:
By segmenting the anchor into two separately stamped parts, the invention eliminates the need for complex casting molds with cores and moving parts. Each part can be stamped using relatively simple dies, and the holes for fasteners are created directly during the stamping process rather than requiring complex mold cavities.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The anchor offers a cost-effective and robust solution for securing heavy components by distributing compressive forces effectively, enhancing stability against vibrations and inertial forces, while simplifying the manufacturing process.
Implementation Method 1
The base and the compression part are joined by welding at least between the surfaces of the end flanges of the base and the force transmission surfaces of the compression part which are in contact with one another

AI summary
The present invention relates to a fixing bracket for bolted joints suitable for being secured on a support surface, comprising a bent and punched sheet metal base comprising a first longitudinal segment having a joining surface, first and second end flanges prolonging from one and the other of the ends of the first longitudinal segment, where both flanges are arranged transverse to the first longitudinal segment and essentially parallel to one another, and where both end flanges comprise a hole such that the line extending between the centers of both holes establishes the longitudinal direction X-X' in which a screw fastener extends; furthermore comprising a bent and punched sheet metal compression part comprising a segment having a cylindrical sector, where the steering axis thereof is parallel to direction X-X', and extending longitudinally from the first end flange to the second end flange; and comprises a force transmission surface at each longitudinal end of the compression part, where one force transmission surface is in contact with the first end flange of the base, and the other force transmission surface is in contact with the second end flange of the base, where the base and the compression part are joined by welding at least between the surfaces of the end flanges of the base and the force transmission surfaces of the compression part which are in contact with one another.
