Solution Overview
Problem
Modern workplaces require flexible and adjustable work surfaces that allow users to alternate between sitting and standing positions, but existing solutions are often expensive or designed for stationary use, lacking flexibility and adaptability.
Innovation Solution
A height adjustable work surface with a platform, leg assembly, and locking mechanism that allows the surface to be raised, lowered, or set to intermediate positions, featuring a biasing mechanism to maintain the raised position and a locking assembly for secure positioning, designed to be compatible with existing desks and providing a sloping surface for ergonomic comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a raise and lower mechanism workstation is used, then the user can alternate between sitting and standing positions, but the workstation becomes expensive
Solution Approach 1:
The workstation is divided into a stationary base unit and a movable riser platform. The base remains fixed while the riser can be raised and lowered independently, allowing position adjustment without requiring the entire workstation to be expensive and complex.
Solution Approach 2:
The riser platform incorporates a raise and lower mechanism with multiple selectable positions, transforming the static workstation into a dynamic one. The locking assembly ensures stability at each position while allowing easy transition between positions.
2Ease of manufacture
If a convertible platform is placed on top of a standard sitting desk, then the cost is reduced, but the platform is designed for stationary use decreasing flexibility
Solution Approach 1:
The platform incorporates a raise and lower mechanism with a locking assembly that enables multiple height positions. This dynamic capability allows the platform to adapt between stationary and adjustable modes, providing flexibility while remaining cost-effective compared to full workstation solutions.
Solution Approach 2:
The platform is designed to work with standard sitting desks while providing additional functionality through its adjustable height capability. It serves both as a stationary overlay and as an adjustable workstation surface, making it universally applicable to different desk configurations.
3Ease of operation
If the leg assembly is moveable between multiple positions, then user mobility and ergonomics are improved, but the device complexity increases
Solution Approach 1:
The height adjustment system is segmented into discrete positionable stops with corresponding locking features. The leg assembly moves between predetermined positions rather than continuously, simplifying the control mechanism while maintaining ergonomic benefits.
Solution Approach 2:
The locking assembly automatically engages at each predetermined position, providing self-servicing functionality. The biasing mechanism works with the locking assembly to maintain positions without requiring complex control systems or continuous user intervention.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a flexible, ergonomic, and adaptable work surface that can be easily adjusted to various heights, enhancing user mobility and reducing the risk of injury by allowing for alternating work positions while maintaining compatibility with standard desks, thus improving workplace ergonomics and user comfort.
Implementation Method 1
A first biasing mechanism may be attached to the platform at a first end and attached to the first slider at a second end, and a second biasing mechanism may be attached to the platform at a first end and attached to the second slider at a second end. The first biasing mechanism and the second biasing mechanism may bias the leg assembly to the raised position.
Implementation Method 2
a torsion spring positioned in the leg assembly and connected to a spring bracket, the link is rotatably fixed to the spring bracket, and the torsion spring is configured to bias the link toward the raised position

AI summary
A height adjustable work surface includes a platform and a height adjustment assembly moveably connected to the platform. A leg assembly is connected to the height adjustment assembly and moveably connected to the platform. The leg assembly is moveable between a raised position, a lowered position, and at least one intermediate position. A locking assembly is moveably connected to the platform. The locking assembly is configured to engage the height adjustment assembly to selectively secure the leg assembly in the raised position, the lowered position, and the at least one intermediate position.
