Adjustable bench
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adjustable benches lack versatility in surface configuration and storage functionality, as they typically offer only a fixed top surface and do not provide easy access to storage compartments.
Innovation Solution
An adjustable bench design featuring a seat that can be selectively mated with a skirt to provide either a flat or sloped top surface, with height adjustable leg assemblies that are slidable and pivotable, and a removable seat allowing access to a storage compartment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the seat is fixed to the skirt, then the bench structure is stable, but the versatility of surface configuration is reduced
Solution Approach 1:
The seat is designed with a wedge shape that allows it to be dynamically positioned in two orientations: apex forward for sloped surface configuration and apex backward for flat surface configuration. This dynamic repositioning capability enables the bench to adapt between different surface configurations without requiring complex mechanical assemblies, hinges, or fastening mechanisms.
2Ease of operation
If the seat is removed for storage access, then the storage compartment is accessible, but the bench structural integrity is compromised
Solution Approach 1:
The bench is segmented into three main components: the seat, the skirt, and the storage compartment. The seat is designed as a separate, removable component that can be easily detached from the skirt to access the storage compartment. This segmentation allows independent access to storage without compromising the structural integrity of the remaining bench framework.
3Adaptability or versatility
If the leg assemblies are made adjustable, then the bench adaptability is improved, but the device complexity increases
Solution Approach 1:
The leg assemblies incorporate telescopic mechanisms with pins and slots that allow dynamic height adjustment. The legs can be extended or retracted to different heights and locked in position using simple pin-and-slot mechanisms, providing height adaptability without complex motorized or hydraulic systems.

AI summary
An adjustable bench comprises a seat, a skirt extending from the seat, and a plurality of height adjustable leg assemblies coupled to the skirt. The seat is shaped to be selectively mated with the skirt to provide the bench with either a flat top or a sloped top surface.
