Rotatable Armrest Cup Holder for Deeper Cup Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing armrest assemblies have poor cup-holding effectiveness and compromise headrest comfort and safety due to the integration of cup holders within the headrest, leading to reduced space and compromised safety features.
Innovation Solution
An armrest assembly design featuring a rotatable headrest with a cup receptacle on its back and a ejectable cup holder mechanism, allowing for enhanced cup holding depth and avoiding excessive headrest space occupation, with adjustable height and locking mechanisms for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the cup holder assembly is arranged inside the headrest, then the cup holder function is integrated, but the depth at which the cup can be held is limited and the holding effect is poor
Solution Approach 1:
The cup holder function is segmented from the headrest structure. The cup holder assembly is now a separate component arranged in the armrest body cavity, while the headrest maintains its original structure for comfort and safety. This segmentation allows the cup holder to have sufficient depth independent of headrest space constraints.
Solution Approach 2:
The cup holder is repositioned from the headrest's internal space to the armrest body's cavity, utilizing a different spatial dimension. The armrest body cavity provides adequate depth for the cup holder to effectively hold cups, while the headrest remains undisturbed for its comfort and safety functions.
2Adaptability or versatility
If the cup holder assembly is arranged inside the headrest, then the cup holder function is integrated, but the internal space of the headrest is occupied resulting in reduced comfort and safety
Solution Approach 1:
The cup holder assembly is segmented as an independent component located in the armrest body cavity rather than being integrated into the headrest. This allows the headrest to maintain its full internal space for comfort and safety features while the armrest body provides the cup holder function.
Solution Approach 2:
The cup holder assembly is extracted from the headrest structure and repositioned to the armrest body. This extraction eliminates the space occupation problem in the headrest, ensuring that headrest components have sufficient space to ensure comfort and safety, while the cup holder function is preserved in its new location.
3Stability of the object's composition
If the headrest is fixed to the armrest body, then the structure is stable, but the angle adjustment for storage and placement is limited
Solution Approach 1:
The headrest connection to the armrest body is changed from a fixed rigid structure to a dynamic rotatable joint. The headrest can now rotate relative to the armrest body within a predetermined angle range, providing adaptability for different storage and placement needs while maintaining structural stability through proper mechanical design of the rotation mechanism.

AI summary
The disclosure relates to an armrest assembly and a vehicle having the armrest assembly. The armrest assembly is configured to be capable of holding a cup. The armrest assembly includes: an armrest body, wherein a cavity and an opening communicating with the cavity are arranged in the armrest body; a headrest, wherein the headrest is rotatably fixed to an end portion of the armrest body close to the opening, and a cup receptacle capable of receiving the cup is arranged on the back of the headrest; and a cup holder mechanism, wherein the cup holder mechanism has a cup holder arranged in the cavity, and the cup holder is ejectable from the opening to hold the cup. With the armrest assembly in the vehicle of the disclosure, the depth at which the cup is held can be increased, the holding effect can be improved, and the comfort and safety of the headrest can be ensured.
