Adjustable Desk Platform With Pivot Arms for Stable Sit-Stand Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional desks do not accommodate the ergonomic needs of alternating between sitting and standing, leading to health issues such as increased mortality rates, fatigue, and circulatory strain, as they fail to provide a seamless transition between these postures.
Innovation Solution
An adjustable desk platform with a set of pivot arms and a locking mechanism that allows the upper platform to move parallel to the lower platform between fully raised and lowered positions, incorporating a keyboard tray for ergonomic support during both sitting and standing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional fixed-height desk is used, then the structure is simple and stable, but it cannot accommodate ergonomic needs of alternating between sitting and standing
Solution Approach 1:
The patent implements a dynamic height adjustment mechanism using pivot arms that allow the upper platform to transition between multiple fixed heights (raised and lowered positions). This dynamic structure enables users to alternate between sitting and standing postures while maintaining structural stability through controlled movement rather than complete rigidity.
Solution Approach 2:
The desk is divided into separate functional components: an upper platform, a lower platform, and pivot arms connecting them. This segmentation allows independent movement of the upper platform relative to the lower platform, enabling height adjustment without compromising the overall structural integrity of the desk.
2Ease of operation
If the upper platform is made movable for height adjustment, then ergonomic comfort is improved, but structural stability may be compromised
Solution Approach 1:
The pivot arm mechanism provides controlled dynamic movement between predetermined raised and lowered positions. The mechanical linkage ensures that the platform moves smoothly and settles stably at each position, maintaining compositional stability during and after adjustment while enabling easy height changes.
Solution Approach 2:
The system changes the vertical position parameter of the upper platform between two fixed states (raised and lowered) corresponding to standing and sitting heights. This discrete parameter change approach maintains stability at each state while allowing easy transition between states for ergonomic adjustment.
3Reliability
If a locking mechanism is added to secure the upper platform, then position stability is improved, but device complexity increases
Solution Approach 1:
The locking mechanism works in conjunction with the dynamic pivot arm system to provide reliable position locking at the raised and lowered states. The mechanism transitions between locked and unlocked states to maintain reliability during position changes while keeping the overall system manageable through integrated design.
4Reliability
If regular breaks from sitting are implemented, then health outcomes are improved, but productivity may be reduced due to posture transitions
Solution Approach 1:
The desk is pre-configured with two optimal height positions (raised for standing, lowered for sitting) that correspond to ergonomic best practices. Users can quickly transition between these predetermined positions without complex adjustments, making it easy to take regular health-breaks while maintaining productivity through minimal disruption to work flow.

AI summary
An adjustable desk platform includes an upper platform defining a substantially planar work surface. A lower platform is located beneath the upper platform. At least one set of pivot arms connect the lower platform and the upper platform, the set of pivot arms including a primary pivot arm and a secondary pivot arm. The set of pivot arms is adapted to move the upper platform substantially in parallel with the lower platform between a fully raised position and a fully lowered position. A locking mechanism is associated with the set of pivot arms. The locking mechanism is adapted to releasably lock the upper platform in the fully raised position and in the fully lowered position. A keyboard tray is suspended below the upper platform, the keyboard tray adapted to support a computer keyboard.
