Dual-Height Seat Riser With Angled Support for Easier Standing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Impaired individuals face challenges in sitting and standing from standard bench seats due to lack of armrests and the difficulty in managing the weight transfer, which can lead to avoidance of public gathering places that require frequent sitting and standing.
Innovation Solution
A dual height seat riser with adjustable elevation and angled seat member, equipped with side handles and a stabilizer, providing a comfortable and supportive seating solution that accommodates different body types and sizes, facilitating easier sitting and standing by offsetting the rearward slope of bench surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If standard bench seating is used, then the seat structure is simple and manufacturing cost is low, but impaired individuals cannot easily sit down or stand up due to lack of armrests and excessive bending required
Solution Approach 1:
The seat is divided into a base portion and a riser portion that can be separated. The riser is further segmented into left and right sidewalls with integrated armrests, allowing the structure to be assembled in simple steps while providing complex functional benefits for impaired individuals.
Solution Approach 2:
The riser adds vertical height to the standard bench seat, creating a dual-height seating system. This dimensional change allows impaired individuals to sit on the elevated riser for easier standing, while the base portion remains at standard height for those with normal mobility.
2Adaptability or versatility
If a single fixed height seat is provided, then the structure is simple, but it cannot accommodate different body types and mobility needs of various users
Solution Approach 1:
The riser can be positioned in two different orientations: upright for elevated seating and tilted back for standard height seating. This dynamic repositioning allows the same structure to adapt to different user needs without requiring complex adjustment mechanisms.
Solution Approach 2:
The seat design serves multiple functions: it provides elevated seating for impaired individuals, standard height seating for able-bodied users, and can be configured in different orientations to accommodate various body types and mobility requirements, all within a single unified structure.
3Ease of operation
If the seat is elevated to assist standing, then ease of standing is improved, but the seat height may be excessive for shorter individuals or those who do not need assistance
Solution Approach 1:
The separation of the riser from the base allows the elevated portion to be selectively used. Taller individuals or those needing assistance can use the riser, while shorter individuals can use only the base portion at standard height, providing adaptability without excessive elevation for all users.

AI summary
A dual-height seat riser or booster provides an elevated seating surface for an adult individual when positioned on, for example, a bench or pew surface. The riser includes a pair of sidewalls having upper and lower edges and a seat member fixed offset to a midline so as to be closer to the upper edge of the sidewall and positioned at an angle so as to slope downward. The riser is configured such that when positioned on a bench with the lower edge of the sidewalls down and the front edge of the seat member forward, the seat member is at a first height, approximately 4 to 16 inches, and when the riser is inverted with the upper edge down and the rear edge forward, the seat member is at a second height, approximately 2 to 8 inches.
