Continuously Adjustable Stand Mechanism for Precise Tray Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional stands for notebook computers and projectors offer limited adjustability, making them ergonomically awkward for long use and difficult to position accurately, and often occupy too much space.
Innovation Solution
A stand with a base, a support member, and a tray that includes a movement mechanism allowing continuous adjustability along a range of travel, enabling the tray to be positioned at an infinite number of locations, and can be locked in place, allowing easy adjustment with minimal force relative to the object's weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional stands with pre-set positions are used, then the structure is simple, but the adjustability is limited and positioning precision is poor
Solution Approach 1:
The stand transitions from fixed pre-set positions to continuous dynamic adjustment along a range of travel, allowing the tray to be positioned at any location rather than limited discrete positions. This is achieved through a movement mechanism that enables smooth positioning throughout the entire travel range.
Solution Approach 2:
The stand allows continuous variation of the position parameter along the range of travel, rather than being constrained to fixed values. The movement mechanism enables the tray position to be adjusted to any value within the travel range, providing infinite positioning options.
2Ease of operation
If traditional stands are used, then the device is simple, but the ease of operation is poor due to difficulty in adjustment
Solution Approach 1:
The movement mechanism incorporates a counterbalancing system that offsets the weight of the tray and supported object, reducing the force required by the user to move the tray. This allows easy adjustment with minimal force, making the stand simple to operate despite the added mechanism complexity.
3Area of stationary object
If video projectors are supported on typical stands, then the support is provided, but the footprint is large and adjustability is limited
Solution Approach 1:
The stand provides continuous dynamic adjustment capability along the range of travel, allowing the tray to reach various positions including extended positions that reduce the footprint. The movement mechanism enables the tray to be positioned at any location, providing adaptability for different projector sizes and support surface configurations.

AI summary
Embodiments of a stand are provided with continuous adjustability within a range of travel. In one embodiment, a stand includes a movement mechanism adapted to allow a tray to move along a range of travel relative to a stand base. The movement mechanism is in some embodiments further adapted to position the tray at an infinite number of locations along the range of travel.
