Support mountable seat assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing boat mountable seat devices lack a secure and adjustable mechanism for attaching a seat to a support, such as a pontoon boat deck, without requiring legs and ensuring user comfort and safety while in water.
Innovation Solution
A seat assembly with a backrest and coupler system that attaches to the boat deck, featuring adjustable rods and brackets for vertical positioning, pivotable backrest for storage, and optional armrests and cushions, allowing for comfortable seating and easy installation/removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a secure attachment mechanism is implemented, then reliability is improved, but device complexity increases
Solution Approach 1:
The attachment system is divided into separate functional components: a coupler body, an adjustable rod with telescopic sections, and a bracket assembly. This segmentation allows each component to perform its specific function while maintaining overall system reliability without excessive complexity.
Solution Approach 2:
The rod includes telescopic sections that can extend and retract, and the bracket can pivot between positions. This dynamic capability allows the attachment mechanism to adapt to different support surfaces and heights, improving reliability across various conditions while using simple mechanical movements rather than complex systems.
2Adaptability or versatility
If adjustable positioning is provided, then adaptability is improved, but device complexity increases
Solution Approach 1:
The rod features telescopic sections that can extend to different lengths and lock into position, enabling vertical adjustment to accommodate various support heights. This dynamic length adjustment provides adaptability without requiring complex mechanical systems.
Solution Approach 2:
The rod's length parameter can be changed by extending or retracting the telescopic sections. This simple parameter change allows the same attachment mechanism to work with supports of different heights, improving adaptability while maintaining mechanism simplicity.
3Ease of operation
If the backrest is made pivotable for storage, then ease of operation is improved, but reliability may worsen
Solution Approach 1:
The bracket is designed to pivot between an engaged position (where it secures to the support) and a disengaged position (for storage). This dynamic movement allows easy operation for storage while maintaining reliable attachment when engaged, as the pivot mechanism includes positive engagement features.

AI summary
A support mountable seat assembly includes a seat having a front end, a back end, a first lateral edge and a second lateral edge. A backrest has a bottom end and a top end. The backrest is attached to and extends upwardly from the back end. The backrest includes a coupler that is attached to the backrest. The coupler receives an outer edge of a support and releasably engages an upper side and lower side of the support.
