Boat Seat Back with Movable Supplemental Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional boat seats often lack adequate head and neck support for passengers in a sitting position, especially when they are not lying low enough on the seat.
Innovation Solution
A seat design featuring a main support and a supplemental support that is movable between a first position forming a back support and a second position forming a head support, allowing for adjustable positioning to provide adequate head and neck support, with the supplemental support being rotatable or translatable via hinges and potentially including features like straps or handles for easy adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional fixed seat back design is used, then the structure is simple, but adequate head and neck support is not provided for passengers in a sitting position
Solution Approach 1:
The seat back incorporates a movable supplemental support that can transition between a stowed position within a recess and an deployed position that provides head and neck support. This dynamic element allows the seat to adapt to different passenger needs while maintaining a compact form when the support is not required.
Solution Approach 2:
The seat back is divided into a main support structure and a separate supplemental support component. The supplemental support can be independently positioned and adjusted, allowing it to provide targeted head and neck support without requiring complete redesign of the entire seat back structure.
2Ease of operation
If a movable supplemental support is added to provide head support, then head and neck support is improved, but the device complexity increases
Solution Approach 1:
The supplemental support is designed to nest within a recess of the main support when not in use. This nesting arrangement allows the movable support to be stored compactly within the existing seat back structure, minimizing additional space requirements and reducing the visual complexity of the overall design.
Solution Approach 2:
The supplemental support serves multiple functions: it provides head support when deployed, stores within the recess when not needed, and can be positioned at different heights along the main support to accommodate various passenger preferences. This multi-functionality reduces the need for separate components for each function.
3Adaptability or versatility
If the supplemental support is made movable between positions, then adaptability is improved, but the manufacturing complexity increases
Solution Approach 1:
The supplemental support incorporates movable elements such as rollers or sliding mechanisms that allow it to be positioned at different heights along the main support. These dynamic components enable easy adjustment during assembly and use, providing adaptability without requiring complex custom fabrication for each position.
Solution Approach 2:
The seat back is segmented into the main support and the supplemental support as separate, modular components. This segmentation allows each component to be manufactured independently using standard fabrication processes, and then assembled together with relatively simple connection mechanisms, reducing overall manufacturing complexity.
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 seat provides enhanced support for boat passengers, allowing them to sit more erect with improved head and neck support, enhancing comfort and safety by accommodating different seating positions without compromising storage within the seat structure.
Implementation Method 1
the supplemental support is rotatable between the first position and the second position, with respect to the main support... hinges, by which the supplemental support is coupled to the main support, and about which the supplemental support rotates
Implementation Method 2
the hinges are one of friction hinges or detent hinges

AI summary
In some examples, a seat for a boat passenger is provided. The seat includes a seat back that has a forward passenger support interface. The seat back includes a main support and a supplemental support. The main support has a recess. The supplemental support is moveable relative to the main support between a first position wherein a first portion of the supplemental support forms part of the forward passenger support interface and a second position wherein a second portion of the supplemental support forms part of the forward passenger support interface. At least a portion of the supplemental support is received in the recess of the main support in the first position and is spaced apart from the recess in the second position.
