Seat Cup Holder Assembly With Leveling Angle Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cup holders integrated with seats, especially child safety seats, cannot adjust the inclined angle of the cup holder, leading to potential spills when the seat is adjusted, as the cup tends to incline with the backrest.
Innovation Solution
A cup holder assembly with a lateral cover, main body, and connection portion that allows adjustable engagement of a positioning rib into sunken portions on the lateral cover, preventing the cup from tilting and ensuring it remains level even when the seat is inclined.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cup holder is integrated with the seat backrest, then the cup holder is stable and securely positioned, but the cup holder cannot adjust its inclined angle independently, causing the cup to tilt and spill when the backrest angle is adjusted
Solution Approach 1:
The cup holder assembly is segmented into a main body and a separate connection portion that can rotate relative to each other. The connection portion connects to the seat backrest while the main body holds the cup, allowing independent angular adjustment of the main body relative to the connection portion. This segmentation enables the cup holder to maintain stability through its secure connection while providing adaptability through the rotatable joint.
Solution Approach 2:
The connection portion is designed with rotational capability, transforming the static cup holder structure into a dynamic one. The connection portion can rotate relative to the main body, allowing the user to adjust the inclined angle of the cup holder independently from the seat backrest angle. This dynamic feature ensures the cup remains level even when the backrest is adjusted.
2Device complexity
If the cup holder structure is made simple and integrated, then the device complexity is reduced, but the ability to prevent cup overturning during seat adjustment is compromised
Solution Approach 1:
The cup holder is divided into a main body and a connection portion that can rotate relative to each other. This simple segmentation allows the connection portion to adjust its angle independently while the main body remains stable, preventing cup overturning during seat adjustment without adding complex mechanisms.
Solution Approach 2:
The rotatable connection portion introduces dynamic adjustment capability into an otherwise simple structure. This allows the cup holder to adapt to different seat angles and prevent cup overturning while maintaining overall structural simplicity and ease of manufacture.
3Device complexity
If the armrest and backrest are integrated, then the seat structure is simplified and more stable, but the cup holder position cannot be adjusted independently from the backrest angle
Solution Approach 1:
The cup holder assembly is segmented into a connection portion that attaches to the integrated armrest-backrest structure and a main body that holds the cup. The connection portion can rotate relative to the main body, allowing independent angular adjustment of the cup holder position while the integrated seat structure remains simple and stable.
Solution Approach 2:
The rotatable connection portion provides dynamic adjustment capability that allows the cup holder position to be independently adjusted from the backrest angle. This maintains the simplicity and stability of the integrated seat structure while adding the necessary adaptability for the cup holder.

AI summary
The present invention provides a cup holder assembly adapted for a seat and the seat with the cup holder assembly. The cup holder assembly includes a lateral cover installed on a lateral side of the seat, a main body, and a connection portion connected to a lateral side of the main body. The connection portion hangs on the lateral cover so as to hang the main body on the lateral cover, and a cup can be disposed inside the main body of the cup holder assembly. It not only has simple structure and convenient operation but also can prevent from overturning the cup.
