Modular Beach Seat with Pivoting Segments and Sand-Mound Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional beach chairs are difficult to manipulate for adjusting the angular orientation of the back or leg portions, which can pinch fingers and add weight, making them cumbersome.
Innovation Solution
A convertible beach seat system with pivotably connected beach seats, armrests, and a method of forming a beach seat by digging a trough for the leg portion and creating a sand-mound back rest, using attachment posts and apertures for detachable assembly and folding, allowing for adjustable and compact configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional beach chairs use hard-to-manipulate mechanisms to retain the back or leg portion at a desired angle, then the angular orientation is maintained, but the mechanism can pinch fingers and add weight to the beach chair
Solution Approach 1:
The patent removes the complex mechanical retention mechanisms from the beach chair design. Instead of using latches, clips, or adjustment mechanisms to hold the back and leg portions at desired angles, the invention allows these portions to be freely adjustable without any retaining structures, thereby eliminating finger pinching risks and reducing weight while maintaining functional reliability through simple geometric constraints
Solution Approach 2:
The beach chair design employs self-supporting structural geometry where the back and leg portions maintain their angular orientations through the inherent stability of the frame structure and cushion positioning rather than active retention mechanisms. The chair serves itself by using its own structural configuration to prevent collapse or unwanted movement without requiring additional mechanical components
2Reliability
If conventional beach chairs use complex mechanisms to adjust angular orientation, then the desired angle is maintained, but the mechanisms add weight to the beach chair
Solution Approach 1:
The patent eliminates all weight-added retention mechanisms (latches, springs, adjustment knobs, and locking structures) from the beach chair design. The back and leg portions are supported solely by the structural framework and cushion placement, removing unnecessary mass while maintaining the ability to retain desired angular orientations through passive structural support
Solution Approach 2:
The invention changes the structural parameters of the beach chair frame and cushion assembly to provide inherent angular retention through geometric configuration rather than mechanical components. By optimizing the frame rigidity, joint geometry, and cushion positioning, the design achieves reliable angle retention with minimal weight addition
3Reliability
If conventional beach chairs use fixed angular mechanisms, then the back and leg portions are retained, but the mechanisms are hard to manipulate
Solution Approach 1:
The patent completely removes complex angular retention mechanisms from the beach chair design. Instead of using multi-component adjustment systems with multiple moving parts, the invention achieves angular orientation retention through simple structural geometry and cushion positioning, making the chair easy to manipulate while maintaining reliability
Solution Approach 2:
The beach chair is divided into separable modules (back portion, seat portion, leg portion) that can be independently adjusted and reconfigured. Each segment can be freely positioned without requiring complex interaction with other segments, simplifying the overall mechanism while maintaining reliable angular retention through individual segment geometry

AI summary
A convertible beach seat system allows a user to form an arrangement of coupled together beach seats and armrests. Also, a method of forming a beach seat in a beach includes digging a trough or trench for receiving the leg portion of the beach seat and forming a sand-mound back rest for the back portion of the beach set to rest thereon. The beach seat system includes a plurality of beach seats, each having a back portion, a seat portion and a leg portion that are pivotably connected about hinges. Each of the beach seats have attachment apertures along the sides for detachably attaching beach seats together by the insertion of attachment posts that extend between the coupled beach seats. Armrests may be detachably attached to the beach seats. Attachment posts are provided for insertion into attachment apertures to coupled together beach seats or armrests to a beach seat.
