Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for adjusting the position of vehicle hoods near the lateral ends of a motor vehicle are difficult due to reduced accessibility, compromising the precision and simplicity of hinge adjustments.
Innovation Solution
A hood assembly and mounting process using a sleeve and threaded locking nuts to adjust and fasten the hinge pin to a structure, allowing precise positioning of the hood near the lateral ends with improved accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the holes for fastening hinges are positioned near the lateral ends of the motor vehicle, then the accessibility of intermediate zones is improved for receiving other devices, but the ease of adjusting the hinge position deteriorates due to reduced accessibility
Solution Approach 1:
The patent introduces a sleeve as an intermediary component between the hinge pin and the chassis hole. The sleeve includes an adjustment mechanism with threaded holes and locking nuts that allows the hinge position to be adjusted without direct operator access to the hole itself. This mediator enables adjustment functionality while maintaining the benefit of having holes positioned near lateral ends for device placement.
2Manufacturing precision
If the hinge position adjustment is made with high precision, then the aesthetic continuity of the vehicle bodywork is improved, but the device complexity increases due to the need for precise adjustment mechanisms
Solution Approach 1:
The patent employs a threaded adjustment mechanism that converts rotational motion into linear displacement, allowing precise control of the hinge position along the longitudinal axis. By changing the parameter of thread pitch and using locking nuts to secure positions, the system achieves high precision adjustment without requiring complex mechanical linkages or multiple adjustment stages.

AI summary
A hood assembly for a motor vehicle includes a hood, a hinge with a first arm, and a pin fixed to the first arm in a projecting manner along a mounting axis and a second arm of the hood hinged to the first arm around a hinge axis, a structural member fixed to the pin and provided with a hole axially receiving the pin along the mounting axis, wherein the hinge axis and the mounting axis lie respectively on a first plane and on a second plane parallel to one another, and wherein a projection of the hinge axis onto the second plane is orthogonal to the mounting axis.
