Telescopic Portable Seat Structure for Compact Storage and Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable seating devices are bulky, cumbersome, difficult to carry, and store, and often challenging to use due to their inflexible designs.
Innovation Solution
A portable seat apparatus featuring a telescopic support member with extendable and retractable concentric sections and a seat receptacle, allowing for configuration between a sit-mode and storage-mode through interlocking features and adjustable height, enabling easy transportation and secure user support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If conventional portable seating devices use fixed rigid structures, then they provide stable user support, but they become bulky and difficult to carry and store
Solution Approach 1:
The telescopic support member employs nested concentric sections where one section is inserted within another, allowing the structure to collapse into a compact form for portability while maintaining full extension capability for stable seating. This nesting mechanism directly resolves the contradiction by enabling the structure to transition between compact storage and stable support configurations.
Solution Approach 2:
The support member transitions from a static fixed structure to a dynamic telescopic structure that can extend and retract. This dynamic capability allows the device to adapt between a compact state for easy carrying and a fully extended state for stable user support, eliminating the need to choose between portability and structural stability.
2Adaptability or versatility
If conventional portable seating devices use fixed height designs, then they are simple in structure, but they lack adaptability to different user needs and terrains
Solution Approach 1:
The telescopic support member provides dynamic height adjustment capability, allowing the seat height to be varied according to different user needs and ground conditions. This dynamic adjustment mechanism adds adaptability while maintaining relatively simple interlocking components that lock at various height positions.
Solution Approach 2:
The support member is divided into multiple discrete telescopic sections that can be independently extended or retracted. This segmentation enables incremental height adjustment while keeping each individual section simple in structure, resolving the contradiction between adaptability and structural complexity.
3Volume of moving object
If conventional portable seating devices use non-collapsible designs, then they maintain structural integrity, but they are difficult to store and transport
Solution Approach 1:
The concentric telescopic sections nest within each other during collapse, reducing the storage volume to a fraction of the extended state. The interlocking features between sections maintain structural integrity during both extended and collapsed states, allowing the device to transition between compact storage and strong support configurations.
Solution Approach 2:
The interlocking features are pre-configured on the telescopic sections to automatically engage and lock when extended, ensuring structural integrity is maintained without requiring additional assembly steps. This preliminary preparation allows rapid deployment while maintaining strength, and enables easy collapse for compact storage.

AI summary
The portable seat apparatus includes a telescopic support member and a seat receptacle. The telescopic support member includes a plurality of concentric sections that are extendable and retractable within each other. The concentric sections include a distal section and a proximal section. Adjacent concentric sections are coupled together via interlocking features. A bottom surface of the seat receptacle is coupled to the telescopic support member and a top surface of the seat receptacle is configured to operably engage a user in a seated position. The apparatus is configurable in a sit-mode and a storage-mode. In the sit-mode, the concentric sections are at least partially extended and the telescopic support member is perpendicular to the seat receptacle. In the storage-mode, the concentric sections of the telescopic member are retracted within each other and the seat receptacle is parallel to the telescopic support member.
