Wave-Shaped Portable Chair With Nested Support Leg Folding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional foldable and stackable beach or pool chairs are typically bulky, difficult to carry, and lack aesthetic appeal, failing to provide a compact, lightweight, and stylish solution for various body sizes.
Innovation Solution
A portable chair with an undulating wave-shaped body and a pivotally attached concave-shaped support leg, made from tubular aluminum or molded plastic, featuring a cable system to maintain the leg in the open position and handles for easy transport, allowing for compact storage and stacking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional foldable beach chairs are designed for storage and carrying, then they can be folded, but they become bulky and difficult to carry
Solution Approach 1:
The support leg nests within the undulating wave-shaped body when in the closed position, with the concave-shaped support leg conforming to the body's contours. This nesting arrangement allows the chair to collapse into a compact form that is easy to carry and store, directly resolving the contradiction between foldability and bulkiness.
Solution Approach 2:
The chair transitions between static (open position for use) and dynamic (closed position for carrying) states through the pivotal attachment of the support leg. The cable system enables smooth transition between states, allowing the chair to adapt its form based on operational requirements, thus achieving both usability and portability.
2Ease of operation
If conventional foldable chairs are designed for storage, then they can be stacked, but they are not compact or lightweight
Solution Approach 1:
The support leg is designed to nest within the undulating wave-shaped body, creating a compact stacked configuration. This nesting mechanism reduces both volume and weight when the chair is in storage position, enabling easy stacking while maintaining lightweight characteristics.
3Ease of manufacture
If conventional beach chairs are made foldable, then they can be stored easily, but they are not stylish or aesthetically pleasing
Solution Approach 1:
The undulating wave-shaped body with its convex and concave curves provides aesthetic appeal while the concave mid-section incorporates handles for easy carrying. The curvature design achieves both stylistic elegance and functional portability, resolving the contradiction between aesthetics and ease of operation.
4Volume of moving object
If the chair is designed to be compact for carrying, then it is easy to transport, but it must be foldable which increases complexity
Solution Approach 1:
The chair is segmented into the undulating wave-shaped body and the pivotally attached support leg, allowing independent movement and compact folding. This segmentation enables the chair to achieve compactness for transport while maintaining relatively simple structural components that are easy to manufacture and assemble.
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 chair is compact, lightweight, easy to carry and stack, aesthetically pleasing, and comfortable for diverse body sizes, offering a unique design that balances style and functionality while maintaining structural integrity and ease of use.
Implementation Method 1
at least one cable having one end mounted to a lower portion of the support leg and the other end mounted to the body to maintain the support leg in the open position
Implementation Method 2
a support leg having an upper portion pivotally attached to the body and movable between a closed position and an open position

AI summary
A portable chair includes an undulating wave-shaped body. The undulating wave-shaped body has a convex lower portion which transitions into a concave mid-section, which in turn transitions into a convex upper portion. The chair further includes a support leg pivotally attached to the body and being movable between a closed position for storage and carrying and an open position for seating. The support leg is concave shaped to substantially conform to the shape of the concave mid-section of the body when in the closed position.
