Rotary Cup Holder with Dynamic Support Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rotary cup holders require increased height to securely hold tall containers, which results in larger storage space requirements when not in use and reduced holding performance when the beverage level decreases, as the elevating mechanism relies on the bottle's weight for support.
Innovation Solution
A rotary cup holder design featuring a lid body with a support part that moves upward via an urging member when opened, allowing for enhanced vertical support without increasing storage space, and a stopper member to maintain the elevated position, ensuring stability even when the bottle's weight is reduced.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cup holder is made larger in height to enhance holding performance for tall containers, then the holding performance is improved, but the storing space required increases
Solution Approach 1:
The support part is designed to move dynamically between a retracted position (when lid is closed) and an extended position (when lid is open). This dynamic configuration allows the cup holder to achieve greater holding height only when needed, while maintaining a compact storing profile when not in use.
Solution Approach 2:
The support part is configured to nest within or adjacent to the holder part when retracted, similar to a nested doll structure. This nesting arrangement maximizes space efficiency during storage while allowing full extension when the cup holder is actively used.
2Reliability
If the support part is kept in an elevated position to provide vertical support, then the holding performance for tall containers is improved, but the storing space requirement increases
Solution Approach 1:
The support part transitions from a static elevated position to a dynamic configuration that retracts when not in use. This allows the system to provide vertical supporting power only when the lid is open and needed, while minimizing depth occupation during storage.
Solution Approach 2:
The support part is designed to move not only vertically but also horizontally or angularly relative to the holder part. This multi-dimensional movement allows the support structure to achieve its elevated supporting position when needed while collapsing or retracting in the depth direction for compact storage.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The cup holder achieves high holding performance for tall containers without needing additional storage space, maintaining support power regardless of the beverage's weight, and allows for flexible installation options.
Implementation Method 1
a support part (3) pivotally held by the holder part (22) and urged by an urging member (4) in a direction of moving apart from the holder part (22)
Implementation Method 2
a stopper member (7) which is urged so as to move apart from the holder part (22) is pivotally held between the support part (3) and the holder part (22), and the stopper member (7) is adapted to be engaged with the support part (3) from below, in an open state of the lid body (2), thereby to prevent the support part (3) from moving downward

AI summary
A cup holder of rotary type has a holder part provided on a back face of a lid body. A support part which is urged so as to move apart from the holder part and pivotally connected to the holder part at its one end will move up and down along with opening and closing motions of the lid body. It is possible to realize the cup holder having high holding performance for a tall container without requiring a large storing space.
