Folding Step Seat with Segmented Frame for Portable Comfort
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a long-felt need for a comfortable seating solution that can be placed on steps or benches to provide ergonomic support and cushioning, and that can be easily stored and transported when not in use.
Innovation Solution
A folding step seat device with a frame that folds for easy transport, featuring a cushion, adjustable legs, and optional straps for carrying, which can be secured in a folded or unfolded position using locking mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a folding mechanism is added to enable easy transport and storage, then the device complexity increases, but the ease of operation deteriorates due to additional locking mechanisms required
Solution Approach 1:
The seat is divided into multiple segments (backrest, seat cushion, legs) connected by hinges, allowing each part to fold independently. This segmentation enables compact storage while maintaining structural integrity during use, resolving the contradiction between ease of transport and device complexity.
Solution Approach 2:
The folding mechanism transforms the static seat into a dynamic structure that can change between extended (for use) and folded (for storage) states. The hinges and locking mechanisms enable this dynamic transformation, allowing the device to adapt its configuration based on operational needs versus storage requirements.
2Reliability
If cushioning and ergonomic support are added to improve comfort, then the device complexity increases, but the reliability of comfort provision improves
Solution Approach 1:
Different parts of the seat are provided with different qualities - the cushion areas have soft padding for comfort, while the frame structure remains rigid for support. The backrest and seat cushion incorporate varying densities of foam or cushioning materials tailored to specific body contact points, providing ergonomic support without uniformly increasing complexity throughout the entire device.
