Mounting Bracket With Rotating Threaded Insert
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in mounting brackets to two separate components, such as an alternator to a cylinder block and a cylinder head, is the gap caused by tolerance stack-up, leading to increased stresses in fasteners and potential damage due to movement and stress on the bracket.
Innovation Solution
A bracket system incorporating a threaded insert and fastener configuration that allows selective repositioning within openings in the cylinder head and cylinder block, using spacers to bridge gaps and secure the bracket firmly, reducing movement and stress on fasteners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a bracket is mounted to two separate components (cylinder head and cylinder block), then the bracket can support heavier loads and provide better stability, but a gap exists due to tolerance stack-up which increases stresses in fasteners and causes bracket movement
Solution Approach 1:
The threaded insert is made rotatable within the opening of the cylinder head, allowing dynamic adjustment of the bracket's position. This enables the bracket to adapt to tolerance variations and eliminate gaps, thereby reducing fastener stress while maintaining the strength benefits of dual-component mounting
Solution Approach 2:
The position of the bracket is adjusted by changing the rotational parameter of the threaded insert. By rotating the insert to different angular positions, the bracket's location can be optimized to eliminate gaps caused by tolerance stack-up, resolving the contradiction between mounting stability and fastener stress
Applied Scientific Principles
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 system effectively reduces bracket movement and stress on fasteners, enhancing the stability and durability of the mounting by allowing adjustable positioning and secure attachment to both components.
Implementation Method 1
The threaded insert includes an exterior surface threadably engaged with the first opening

AI summary
A bracket includes a bracket body, a threaded insert, and a fastener. The bracket body defines a first opening positioned to align with a second opening in a cylinder head. The threaded insert is positioned in the first opening. The threaded insert includes an exterior surface threadably engaged with the first opening, an inner surface defining an aperture, and an end face. Rotation of the threaded insert in the first opening facilitates selective repositioning of the threaded insert in the first opening. The fastener is configured to be received in the aperture of the threaded insert. The aperture is configured to receive a tool for selective rotation of the threaded insert.
