Vehicle Console Lid Damping Mechanism for Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle console assemblies with armrest lids often experience wobbling or excessive noise due to inadequate control over lid movement, lacking a mechanism to smoothly transition between raised, lowered, and intermediate positions.
Innovation Solution
A console assembly design featuring a body with support extensions and resilient members that define channels, where a connector and engagement member interact with the resilient members to stabilize the lid, allowing it to rotate smoothly between positions via a hinge pin, with frictional engagement providing stability and minimizing noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional hinge assembly is used to couple the armrest lid to the console bin, then the lid can be operated between opened and closed positions, but the lid experiences wobbling and excessive noise due to inadequate control over lid movement
Solution Approach 1:
A damper assembly is introduced as an intermediary component between the lid and console bin. The damper assembly includes a rod that interfaces with the hinge assembly and a piston that moves within a bore, creating a damping mechanism that controls lid movement without requiring a complete redesign of the hinge system
Solution Approach 2:
The damper assembly changes the movement parameters of the lid by providing viscous damping through the piston-bore interaction. This controls the speed and smoothness of lid transitions, reducing wobbling and noise while maintaining the ability to operate between opened and closed positions
2Ease of operation
If the lid is allowed to rotate freely between raised and lowered positions, then ease of operation is improved, but stability and control over intermediate positions deteriorates
Solution Approach 1:
The damper assembly acts as a mediator that provides continuous damping force during lid rotation, allowing free movement while simultaneously providing stability control. The piston-bore mechanism creates viscous resistance that smooths transitions and stabilizes intermediate positions without restricting operability
Solution Approach 2:
The damper assembly provides dynamic damping force that adapts to the lid's movement state. The viscous damping characteristic allows the system to maintain stability during motion while providing controlled deceleration, enabling both ease of operation and intermediate position stability

AI summary
A console assembly includes a body that has a front portion and a rear portion. The body defines a support extension extending from a rear portion. The support extension includes a guide and a resilient member that defines a channel. A lid is operably coupled to the body. A connector outwardly extends from the lid and is coupled to the support extension. An engagement member is positioned within the channel and is coupled to the connector and mutually engageable with the resilient member.
