Dual-Clutch Gearbox Vibration Absorber With Single-Carrier Fixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing damper arrangements for motor vehicle drive trains face issues with high reject rates during quality inspection and operational problems due to overdetermination when both absorber carriers are attached to the drive train element, leading to functional delays.
Innovation Solution
Only one absorber carrier is fixed to the drive train element, with the other carrier remaining non-determined, allowing for a releasable attachment via a screw or rivet, and spacer elements are used to maintain spacing and facilitate assembly access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If both damper carriers are fixed to the drive train element, then the damper attachment appears more secure, but overdetermination occurs leading to distortion and functional problems
Solution Approach 1:
The patent extracts the fastening function from one of the two damper carriers, leaving it unfixed. This removes the overdetermination conflict by having only one carrier (the other being extracted from the fastening system) attached to the drive train element, thereby eliminating distortion while maintaining secure attachment through the single fixed carrier
2Stability of the object's composition
If both damper carriers are riveted to the drive train element, then the attachment appears more stable, but distortion occurs leading to quality control rejections
Solution Approach 1:
The patent extracts the riveting fastening from one damper carrier, leaving it without attachment to the drive train element. This prevents the overdetermination that causes distortion during assembly, thereby improving manufacturing precision and reducing quality control rejections while maintaining stability through the single riveted carrier
3Strength
If both damper carriers are attached to the drive train element, then the structural integrity appears enhanced, but operational problems arise due to overdetermination
Solution Approach 1:
The patent extracts the attachment function from one damper carrier, leaving it unfixed relative to the drive train element. This eliminates the overdetermination conflict that causes operational problems, allowing the damper to function smoothly while maintaining structural integrity through the single attached carrier
