Detachable Folding Seat Support for Fast Spectator Stand Setup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing movable spectator stand structures face challenges in being lightweight, easy to handle, and quick to set up and dismantle, while also requiring sturdy support structures to manage stress, which increases material and production costs, and existing solutions either overburden the stand or complicate the installation and dismantlement process.
Innovation Solution
A folding seat design with pivotably attached leg parts and a support member using a mounting pin system, where the leg part is locked in place during use and easily detachable for storage, allowing for efficient setup and teardown, and a spectator stand element with a detachable folding seat and support member that reduces manufacturing costs and simplifies handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the stand structure is made sturdy to manage stress, then structural integrity is improved, but weight and material costs increase
Solution Approach 1:
The stand structure is divided into separate modular components: base units with integrated support members, leg parts, and seat assemblies. Each component can be independently manufactured with optimized material distribution, allowing lighter individual parts that collectively provide the required structural integrity when assembled. The support members are segmented into distinct functional zones (locking mechanism area, mounting pin area, leg contact area).
Solution Approach 2:
The support member incorporates localized reinforcement only where structurally necessary - specifically at the locking part and mounting pin regions that bear the primary loads. The elongated first hole and locking mechanism are designed with concentrated material in high-stress zones while maintaining lighter construction in less critical areas, optimizing the strength-to-weight ratio of the overall stand structure.
2Ease of operation
If the seat is completely detached from support structures for storage, then handling ease is improved, but installation and dismantlement time increase
Solution Approach 1:
The connection between the leg part and support member transitions from a static fixed connection to a dynamic reversible connection. The locking mechanism allows the leg part to be quickly locked into position during use and just as quickly released for storage. The mounting pin with elongated first hole provides a connection that is secure during operation but easily disengaged when needed, enabling rapid reconfiguration between operational and storage states.
Solution Approach 2:
The mounting pin acts as an intermediary element that facilitates quick connection and disconnection between the leg part and support member. The elongated first hole in the support member and corresponding mounting hole in the leg part create a simple pin-and-hole interface that enables rapid assembly and dismantlement without complex fastening procedures, significantly reducing the time required to set up or take down the spectator stand.
3Stability of the object's composition
If the leg part is locked in place during use, then stability is improved, but device complexity increases
Solution Approach 1:
The locking function is extracted as a separate, dedicated feature within the support member - the locking part with locking hole that receives and secures the leg part. This dedicated locking feature works in conjunction with the mounting pin system, providing stable locked positioning without requiring a complex integrated locking mechanism. The simplicity of the locking part design minimizes additional complexity while ensuring stable leg part positioning during use.

AI summary
The invention relates to a folding seat, which has two leg parts (10a, 10b) and at least one seat level (18), which is pivotably attached to the leg parts. In the first end of the leg part has been arranged a support member (40), with the aid of which the seat is pivotably attached to a base (100). The support member has a first edge (42) which settles against the leg part, which first edge has an elongated first hole (43) for a mounting pin (46) of the leg part, and a second edge (44) which is settled against the base, which second edge has a locking part for receiving and locking in place the first end of the leg part. The locking part is preferably a second hole (45) or opening, wherein the first end of the leg part can be fitted. The first end of the leg part is unlocked when the leg part is lifted upwards as much as the first hole allows for. The seat can be folded into a storage position, where the leg parts, backrest (20) and seat level of the seat settle in a substantially horizontal position on the base. The invention also relates to a support member of a seat and a spectator stand element, which comprises a base and at least one folding seat according to the invention, which is attached in a detachable manner to the base. The spectator stand element further includes a cover plate (58), which can be attached to the support member in place of the seat, which has been detached from the spectator stand element.
