Suspended Stadium Seat Structure for Adjustable Ergonomic Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable stadium seats are often uncomfortable, especially for users with back or joint conditions, as they lack adequate support and padding, and typically require sitting directly on a hard surface.
Innovation Solution
A portable seating apparatus with a frame and a suspended seat, adjustable straps for height and inclination, and a foldable design for ease of transport and storage, providing enhanced stability, support, and comfort by elevating the user above the bench surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional portable stadium seats use a flat seating area and flat back rest, then the device complexity is reduced, but user comfort deteriorates due to lack of ergonomic support
Solution Approach 1:
The patent applies the dynamics principle by making the seat surface and backrest flexible rather than rigid. The suspended seat allows the surface to conform dynamically to the user's body shape, providing ergonomic support without requiring complex rigid structural components. This flexible adaptation resolves the contradiction between comfort and simplicity.
2Ease of operation
If the seat is suspended from the frame by straps, then user comfort is improved by distributing weight and elevating above hard surface, but device complexity increases
Solution Approach 1:
The patent changes the physical state and configuration parameters of the suspension system by using adjustable straps with buckles. This allows the suspension length and tension to be modified according to user needs, providing comfort through weight distribution while keeping the suspension system simple and adaptable rather than complex and fixed.
3Adaptability or versatility
If adjustable straps are used to raise or lower seat height and incline the seat, then adaptability is improved, but device complexity increases
Solution Approach 1:
The adjustable straps with buckles implement the dynamics principle by allowing the seat position and inclination to be changed dynamically according to user preferences. This simple adjustment mechanism provides high adaptability for different users and conditions without requiring complex mechanical systems, resolving the contradiction between versatility and simplicity.
4Ease of operation
If the frame is foldable for ease of transport and storage, then ease of operation is improved, but structural strength may deteriorate
Solution Approach 1:
The foldable frame applies the segmentation principle by dividing the frame into multiple hinged sections that can be folded together for compact transport. The frame maintains structural strength through proper hinge design and material selection, allowing it to collapse into a portable configuration while still supporting the suspended seat and user weight when deployed, resolving the contradiction between portability and strength.

AI summary
A portable seating apparatus includes a frame having first and second sides. A seat is disposed between the first and second sides of the frame. The seat is suspended between the first and second sides of the frame by multiple tension members such as straps. A first arm rest and first base member are positioned on the first side of the frame, and a second arm rest and second base member are positioned on the second side of the frame. One or more straps extends downwardly from each arm rest to support the suspended seat. In some embodiments, the first and second sides are hinged such that the seating apparatus may be folded for transport and storage. An arm rest hinge is disposed on each arm rest, and a base member hinge is disposed on each base member in some embodiments.
