Seat device and seat device system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing seating devices either have complex structures that are difficult to transport and expensive, or simpler designs that fail to provide adequate support for an ergonomic sitting position, leading to poor posture and associated health issues.
Innovation Solution
A seating device with an ellipsoidal outline, comprising a base body and a removable cover part made of elastic material, allowing adjustable height and flexibility to promote an ergonomic sitting position similar to the heel seat, while being versatile and accessible in various sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex seating device structure is used to provide ergonomic support, then the ergonomic support function is improved, but the device complexity and transportation difficulty increase
Solution Approach 1:
The seating device is divided into two main segments: a base body and a cover part. The cover part can be completely or partially removed from the base body, allowing for simplified transportation and storage while maintaining the ergonomic support function when assembled. This segmentation resolves the contradiction by enabling the device to provide full ergonomic support during use but be easily transported when disassembled.
Solution Approach 2:
The cover part is designed to be movable relative to the base body, transitioning between attached and removed states. This dynamic configuration allows the device to adapt between providing complete ergonomic support (when assembled) and being easily transportable (when disassembled), resolving the contradiction between structural complexity and transportation ease.
2Reliability
If the seat height is lowered to achieve heel-sitting position, then the ergonomic back support is improved, but the usability in everyday situations deteriorates
Solution Approach 1:
The seating device provides localized elevation at the seat surface through the cover part, which creates a heel-sitting position that supports the back ergonomically. This local modification of the seating surface allows the user to achieve proper posture without requiring the entire seat to be at an elevated position, thus maintaining usability in everyday situations while providing ergonomic back support.
3Ease of operation
If the cover part is made of elastic material for comfort, then the seating comfort is improved, but the structural stability deteriorates
Solution Approach 1:
The seating device uses a composite structure where the base body is made of a stable, rigid material providing structural support, while the cover part is made of elastic material providing seating comfort. This combination of materials with different properties resolves the contradiction by allowing the rigid base to maintain structural stability while the elastic cover enhances comfort.
Solution Approach 2:
The elastic material is applied locally to the cover part that directly contacts the user, providing comfort where needed. The base body maintains rigid material properties for overall structural stability. This localized application of different material properties resolves the contradiction between comfort and stability.
