Rotatable Seat Assembly With Tablet Arm and Base Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional seating options are not flexible enough to accommodate various seating arrangements for group learning, do not provide adequate storage or easy access to personal belongings, and fail to offer a range of postural choices suitable for diverse users, while also being economical.
Innovation Solution
A seating unit with a rotatable seat structure and a tablet assembly that includes a support arm with a pivot assembly, allowing the tablet to rotate freely while preventing contact with the seat, combined with a stable base with storage capabilities and adjustable features to accommodate different user sizes and postures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional seating options are used, then comfort and simplicity are maintained, but flexibility for various seating arrangements and adaptability to group learning is insufficient
Solution Approach 1:
The seating unit is divided into separable components: a base with mounting assembly and a seat structure with mounting bracket. This segmentation allows the seat to be easily attached to different base configurations (single base, dual bases, varying heights) without redesigning the entire seating system, thereby improving adaptability while keeping individual components simple.
Solution Approach 2:
The mounting bracket and mounting assembly use standardized female and male connectors that can accommodate multiple base configurations. The same seat structure can be mounted on single bases, dual bases, adjustable height bases, or fixed height bases, making the seating unit universal across different learning environment requirements.
2Adaptability or versatility
If traditional seating options are used, then manufacturing simplicity is maintained, but storage capability and access to personal belongings are insufficient
Solution Approach 1:
The mounting bracket is integrated directly into the seat structure, and the mounting assembly is integrated into the base. This merging eliminates the need for separate mounting mechanisms and allows storage compartments to be built into the base structure itself, providing storage functionality without adding significant complexity to the overall design.
3Adaptability or versatility
If traditional seating options are used, then cost-effectiveness is maintained, but range of postural choices and accommodation for diverse users is insufficient
Solution Approach 1:
The mounting system allows the seat structure to be positioned at different heights and orientations by selecting different base configurations. The adjustable height bases and varying base arrangements enable users to customize their seating position and posture, providing dynamic adaptability for diverse user needs without requiring complex active adjustment mechanisms.
4Ease of operation
If mounting bracket with female connector and mounting assembly with male connector are used, then ease of assembly is improved, but manufacturing precision requirements increase
Solution Approach 1:
The male and female connectors are designed with asymmetric geometries that provide visual and tactile guidance for proper alignment during assembly. The asymmetric shapes ensure that components can only be assembled in the correct orientation, reducing alignment errors while maintaining ease of assembly through intuitive fitting.
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 seating unit promotes interaction and collaboration by providing flexible seating arrangements, easy access to personal belongings, and accommodating various postures, while maintaining stability and durability at a low cost.
Implementation Method 1
The bushing is inserted into the support arm second end such that the projection protrudes through the cutout. The bottom of the inner tube is inserted into the bushing and the top of the inner tube is inserted into the connecting portion.
