Vehicle Card Holder Assembly Vibration Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing card holding assemblies for vehicles fail to effectively reduce vibration, leading to instability and movement of disposable cards during operation, which affects their usability and durability.
Innovation Solution
A card holding assembly comprising a card retaining sleeve, a collar, and a holder that are in fixed and removable communication, with features such as cut-out edge portions, tabs, and ridges for engagement, and a collar support post to provide stability and reduce vibration transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple card holding assembly is used, then the device complexity is reduced, but the vibration reduction capability deteriorates
Solution Approach 1:
The patent implements a nested structure where the card is held within a sleeve, which is mounted in a holder, which in turn attaches to the vehicle. This multi-layer nesting approach provides vibration reduction through distributed mounting points and structural damping while maintaining a compact, integrated design that does not excessively increase complexity.
Solution Approach 2:
The card holding assembly is divided into separate functional segments: the card itself, the sleeve that holds the card, the holder that mounts to the vehicle, and the mounting mechanism. This segmentation allows each component to be optimized for its specific function while collectively providing vibration reduction through the distributed structure.
2Stability of the object's composition
If the card holding assembly is securely fixed to reduce movement, then the stability is improved, but the ease of removing and replacing cards deteriorates
Solution Approach 1:
The mounting mechanism incorporates dynamic elements that allow the assembly to be securely fixed during operation while enabling easy removal when needed. The collar and holder design provides stable engagement through friction and geometric constraints during normal use, but allows deliberate disengagement through a simple removal action, transitioning between stable and removable states as needed.
Solution Approach 2:
The sleeve acts as an intermediary element between the card and the holder, providing a interface that secures the card firmly during operation while allowing easy insertion and removal. The collar serves as another intermediary that mediates between the sleeve and the holder, enabling stable mounting while facilitating simple detachment.
3Reliability
If vibration reduction features are added to the collar and holder, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The collar and holder incorporate features that change geometric parameters to reduce vibration, such as ridges that increase friction, cut-out edge portions that provide engagement points, and tabs that distribute mounting stresses. These parameter changes are achieved through standard manufacturing techniques rather than complex mechanisms, providing vibration reduction with minimal increase in overall device complexity.
