Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle body vibration damping apparatuses face challenges in compact mounting due to high tightening torque, leading to distortion and increased part count, which restricts other component placements and increases manufacturing costs.
Innovation Solution
A mount structure featuring a hydraulic damping force generation means with an extended section on the mounting bolt's head, allowing for correct mounting to a vehicle body frame without dedicated brackets, using a male screw for secure attachment and reducing the number of parts required.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If high tightening torque is applied to mount the vibration damping apparatus to the body frame, then the mounting firmness is improved, but the apparatus becomes distorted and mounting precision deteriorates
Solution Approach 1:
The mounting system is segmented into two independent parts: the body frame mounting (using original mounting bolts) and the vibration damping apparatus mounting (using separate mounting bolts with extended sections). This segmentation allows each part to be tightened to its optimal torque independently, preventing distortion while ensuring firm mounting.
Solution Approach 2:
The extended section of the mounting bolt acts as an intermediary element that provides a dedicated mounting interface for the vibration damping apparatus. This intermediary structure allows the apparatus to be mounted separately from the main suspension system, enabling independent torque control and preventing the transmission of high tightening forces that would cause distortion.
2Manufacturing precision
If dedicated mounting brackets are used to mount the vibration damping apparatus, then the mounting correctness is improved, but the number of parts increases and device complexity worsens
Solution Approach 1:
The mounting function is merged into the existing suspension system mounting structure. The vibration damping apparatus is mounted directly to the body frame using the same mounting bolts that secure the suspension system, eliminating the need for separate dedicated mounting brackets and reducing overall part count.
Solution Approach 2:
The mounting bolts serve multiple functions: they simultaneously mount both the suspension system and the vibration damping apparatus to the body frame. This multi-functionality eliminates the need for dedicated single-purpose mounting brackets, simplifying the overall structure while maintaining correct mounting alignment.
3Manufacturing precision
If dedicated mounting brackets are used, then the mounting correctness is improved, but the occupied space increases and compactness deteriorates
Solution Approach 1:
The mounting structure is merged with the existing suspension system mounting points on the body frame. By utilizing the existing mounting locations and structures, the vibration damping apparatus is mounted in a compact manner without requiring additional space for separate mounting brackets.
Solution Approach 2:
The unnecessary mounting bracket component is extracted from the system. The invention directly mounts the vibration damping apparatus to the body frame using the existing suspension mounting bolts, removing the redundant bracket structure and thereby reducing the occupied space.
