Modular Chair with Releasable Arm Assemblies for Versatile Portability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional beach and garden chairs are often limited in their versatility and portability, as they are designed for specific uses and are not easily adaptable to different environments or surfaces, making them less versatile and harder to transport and store.
Innovation Solution
A modular chair design featuring a seating portion, back portion, and lateral support arm assemblies with pivot members and extender frames that allow for adjustable positions and easy disassembly, enabling the chair to be configured for various uses and surfaces, and compact storage and transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional beach and garden chairs are designed for specific uses, then they provide functional stability for that specific purpose, but they lack versatility for different environments and surfaces
Solution Approach 1:
The chair is divided into separate modular components including a seating portion, back portion, lateral support arm assemblies, and extender frames. Each component can be independently assembled or disassembled, allowing the chair to be configured for different uses and environments while maintaining functional stability through proper component design
Solution Approach 2:
The modular components are designed with universal connection features that allow the same basic components to serve multiple functions across different chair configurations. The lateral support arm assemblies can be positioned in various locations, and the extender frames can be attached to create different chair types (beach chair, garden chair, lounge chair) from the same component set
2Ease of operation
If conventional chairs are designed as fixed structures, then they provide structural stability, but they are difficult to transport and store
Solution Approach 1:
The chair structure is segmented into multiple components connected by releasable connections, allowing the chair to be easily disassembled for transport and storage. The lateral support arm assemblies can be detached from the seating portion, and the extender frames can be removed, reducing the overall size and weight for convenient handling while maintaining structural integrity when assembled
Solution Approach 2:
The chair incorporates movable and adjustable components including pivot members that allow the back portion to rotate between vertical and reclined positions, and lateral support arm assemblies that can be positioned at different locations. These dynamic features allow the chair to adapt to different user needs while maintaining structural stability through secure connection mechanisms
3Adaptability or versatility
If a modular chair includes multiple adjustable components, then it provides enhanced versatility and adaptability, but it increases the complexity of assembly and disassembly
Solution Approach 1:
The chair is divided into clearly defined modular components with standardized connection interfaces. The lateral support arm assemblies, extender frames, and back portion each have specific attachment points and connection mechanisms that simplify the assembly process, allowing users to quickly assemble and disassemble the chair without dealing with complex internal structures
Solution Approach 2:
The components are pre-configured with connection features and attachment points positioned for optimal assembly efficiency. The lateral support arm assemblies include pre-positioned connectors that align with corresponding receptacles on the seating portion, and the extender frames include pre-drilled holes and mounting brackets that facilitate quick attachment, reducing the time and effort required for assembly

AI summary
A modular furniture seat assembly comprises a seating portion having a front end, a rear end, a pair of opposing side edges, and a seating connector component on each of the opposing side edges. A back portion is provided and has a lower end, an upper end, and a pair of opposing side edges. The lower end of the back portion connects to the rear end of the seating portion. A pair of lateral support arm assemblies is provided, each having an inner surface and an outer surface, with each of the pair of lateral support arm assemblies having a first arm connector component which is releasably connectable to the seating connector component. The lateral support arm assemblies comprise an armrest portion and a leg portion, with the leg portion supporting the modular furniture seating item when it is an assembled condition.
