Adjustable desk platform
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional desks do not accommodate the need for ergonomic transitions between sitting and standing, leading to health issues associated with prolonged sitting or standing, such as increased mortality rates, fatigue, and circulatory strain, while also failing to provide easy and quick adjustments for user comfort.
Innovation Solution
An adjustable desk platform with a planar work surface, a legless base for mounting on existing desks, and pivot arms that allow the platform to move between fully raised and fully lowered positions, incorporating locking mechanisms, biasing mechanisms, and counterweights for ease of use and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed desk is used, then the structure is simple and stable, but it cannot accommodate transitions between sitting and standing positions
Solution Approach 1:
The desk is divided into a stationary base and a movable upper platform, allowing the platform to be adjusted independently between sitting and standing positions while the base remains fixed and simple
Solution Approach 2:
The upper platform is made dynamically adjustable through pivot arms and locking mechanisms, enabling transitions between fixed positions (sitting height and standing height) while maintaining stability when locked
2Ease of operation
If standing desks are used, then standing position is supported, but prolonged standing increases circulatory strain and fatigue
Solution Approach 1:
The desk allows dynamic switching between sitting and standing positions, enabling users to alternate postures throughout the day to avoid the harmful effects of prolonged standing while maintaining ergonomic support when standing is necessary
3Productivity
If quick position changes are enabled, then productivity is improved, but the mechanism becomes more complex
Solution Approach 1:
Counterweights are incorporated into the pivot arm mechanism to balance the weight of the upper platform, reducing the effort required to move it between positions and enabling quick transitions without requiring complex motorized systems
Solution Approach 2:
The locking mechanism is designed to be easily operated by the user without requiring assistance or complex procedures, allowing quick and independent position changes that enhance productivity
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
Enables quick and easy transitions between sitting and standing positions, promoting user comfort and reducing health risks by allowing for customizable height adjustments and reducing the effort required to change positions, thus enhancing productivity and reducing fatigue.
Implementation Method 1
the base includes a counterweight adapted to offset weight of the upper platform when in the raised position
Implementation Method 2
a biasing mechanism associated with at least one of the first and second sets of arms, wherein moving the upper platform toward the fully raised position loads the biasing mechanism

AI summary
An adjustable desk platform can include: an upper platform defining a substantially planar work surface; a base located beneath the upper platform, the base defining a bottom surface without legs that is adapted to sit on an existing desk; first and second sets of arms coupling the upper platform to the base, wherein the first and second sets of arms are adapted for movement of the upper platform substantially in parallel with the base between a fully raised position and a fully lowered position; and a user-operable locking mechanism associated with the upper platform, the locking mechanism adapted to releasably lock the upper platform in the fully raised position, and in at least one intermediate position between the fully raised position and the fully lowered position. Other features and embodiments are discussed.
