Sofa Armrest with Rotatable Cupholder and Hidden Function Rack
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sofas with cupholders and storage grooves on the armrests compromise the appearance and privacy, especially when designed for soft armrests, as they are exposed and affect the overall shape.
Innovation Solution
A multifunctional sofa design featuring a middle armrest with a rotatable cupholder and a movable function rack that can be hidden or exposed, allowing for convenient placement of items without compromising the sofa's appearance, including a function table with cup slots and storage grooves.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If cupholders and storage grooves are exposed on the armrests, then user convenience is improved, but the sofa appearance and privacy are compromised
Solution Approach 1:
The cupholder and storage groove are designed as movable components that can rotate between an exposed position (providing user convenience) and a hidden position (maintaining sofa appearance). The armrest assembly includes a rotating mechanism that allows these functional elements to dynamically adjust their visibility and accessibility based on user needs.
2Ease of operation
If cupholders are arranged on the upper surface of soft armrests, then tea cups can be conveniently placed, but the overall shape and appearance of the sofa are affected
Solution Approach 1:
The cupholder is designed as a rotatable component integrated into the armrest assembly rather than being fixed on the upper surface. This allows the cupholder to be rotated into position for use and then rotated back to be hidden, dynamically adjusting the armrest's shape and appearance while maintaining cup placement functionality.
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
Provides users with multiple functional areas while maintaining a sleek appearance, as the cupholder and function rack can be selectively hidden or exposed, enhancing user convenience without altering the sofa's style.
Implementation Method 1
An outer cover is also provided outside the cupholder. The outer cover may rotate relative to the cupholder to allow the at least one cup slot to be unfolded or folded.
Implementation Method 2
a movable function rack which can rotate outwards relative to the armrest assembly is arranged in the accommodating groove

AI summary
A multifunctional sofa includes armrest assemblies and seat units. A middle armrest is arranged between the adjacent seat units, and a front end of the middle armrest is provided with a cupholder. An upper end surface of the cupholder is provided with a cup slot, and an outer cover is also provided outside the cupholder. The outer cover may rotate relative to the cupholder to allow the one cup slot to be unfolded or folded. A movable function rack capable of rotating outwards relative to the armrest assembly is arranged in each of armrest assemblies. The movable function rack is provided with a function table. In the hidden position, the movable function rack is entirely located in the accommodating groove. In the use position, the movable function rack rotates outwards from the accommodating groove to protrude from the armrest assembly, and the function table is exposed outside.
