Moveable Seat with Gas Spring for Sit-Stand Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing seating solutions do not adequately support users in both seated and standing positions, failing to provide the necessary adjustments for comfortable transitions between these postures.
Innovation Solution
A moveable seat design featuring a seat base supported by a cantilever arm and pivot shaft, with an adjustment mechanism like a gas spring, allowing the seat to move between seated and standing positions, and optionally intermediate positions, while maintaining user contact and absorbing shock, using a travel path that provides greater displacement and simpler mechanisms for user support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed seat design is used, then the structure is simple, but it cannot provide support for both seated and standing positions
Solution Approach 1:
The seat base is made movable rather than fixed, allowing it to transition between different positions (seated and standing) along a defined travel path. The connection device enables this dynamic movement while maintaining structural integrity, resolving the contradiction between adaptability and simplicity.
2Adaptability or versatility
If a moveable seat with cantilever arm and pivot shaft is used, then the seat can transition between seated and standing positions, but the mechanism complexity increases
Solution Approach 1:
The connection device serving as both the cantilever arm and pivot mechanism performs multiple functions: it supports the seat base, enables rotational movement, and guides the travel path. This multi-functionality reduces the need for separate components, thereby reducing overall mechanism complexity while maintaining position adjustment capability.
3Ease of operation
If the seat base is moveable along a travel path, then user support is improved, but the manufacturing complexity increases
Solution Approach 1:
The support system is divided into distinct functional segments: the seat base, the connection device (cantilever arm), the pivot shaft, and the adjustment mechanism. This segmentation allows each component to be manufactured independently using standard processes, then assembled together, reducing overall manufacturing complexity while maintaining user support quality.
4Reliability
If an adjustment mechanism like gas spring is added, then the seat can maintain user contact and absorb shock, but the device complexity increases
Solution Approach 1:
A gas spring mechanism is used to provide controlled support and shock absorption. The pneumatic element absorbs shocks and maintains consistent user contact during transitions, while requiring minimal structural modifications. This approach achieves reliable user contact with relatively simple implementation compared to mechanical spring or hydraulic systems.
