Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current portable desks are limited by their footprint, create tripping hazards, and are cumbersome for elderly and parents with children, as they rely on legs and casters, making them unsuitable for flexible home office setups and space-efficient use.
Innovation Solution
A suspendable, ergonomic, space-saving work surface with height and angle adjustment, allowing it to be hung from doors or windows without legs, using a suspender system with adjustable loops and straps for easy positioning and compact storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional portable desks use legs and casters for support and mobility, then they provide structural stability and ease of movement, but they occupy valuable floor space, create tripping hazards, and are cumbersome for elderly persons and parents with children
Solution Approach 1:
The patent transitions the desk from a floor-based support system (legs and casters) to a wall-mounted suspension system. By anchoring the desk to the wall, the support function moves from the horizontal floor plane to the vertical wall plane, eliminating the need for floor space occupation while maintaining structural stability and ease of movement.
Solution Approach 2:
The patent removes the legs and casters from the desk structure entirely. By extracting these floor-contact components and replacing them with wall-mounted suspenders, the design eliminates tripping hazards and floor space occupation while preserving the desk's mobility and stability through the suspension mechanism.
2Area of moving object
If traditional work desks have a large footprint to provide adequate work surface area, then they offer sufficient workspace, but they cannot be easily stowed and interfere with household activities
Solution Approach 1:
The patent utilizes the vertical wall space for storage when the desk is not in use. By mounting the desk on the wall, the work surface can be positioned horizontally for use, then rotated or folded vertically against the wall for stowing, transforming the storage dimension from horizontal floor space to vertical wall space.
Solution Approach 2:
The patent incorporates a dynamic suspension mechanism that allows the desk to be easily adjusted between horizontal working position and vertical stowed position. The suspenders enable smooth rotation and positioning, making the desk adaptable to different states (in use vs. stored) without requiring complex assembly or disassembly.
3Reliability
If adjustable height work surfaces are used to improve ergonomics and blood flow, then health benefits are achieved, but the device complexity and structural requirements increase
Solution Approach 1:
The wall-mounted suspension system serves multiple functions: it provides structural support, enables height adjustment, allows angle positioning, and facilitates easy stowing. By making the suspenders multi-functional, the design achieves ergonomic adjustability without proportionally increasing structural complexity, as the same suspension mechanism handles multiple adjustment requirements.
Solution Approach 2:
The patent divides the height and angle adjustment functions into separate, independent suspension components. This segmentation allows each suspender to be optimized for specific adjustment tasks while maintaining overall structural simplicity, as individual components can be adjusted without affecting the entire system.

AI summary
Disclosed is an activity support device including a body having at least one activity support surface, and at least one suspender integrated with the body and adapted to suspend the body from a support structure, wherein integration of the suspender with the body enables adjustment of an angle of the support surface relative to the support structure. In preferred embodiments, the suspender includes a support loop having a length and the loop is releasably secured to the body along the length. Preferably, the body can be released and resecured to the loop to enable adjustment of a position of the body relative to the loop, and adjusting the position changes the angle of the support surface relative to the support structure. Preferably, the body has an underside opposite the support surface, and the loop passes through a first through hole from the support surface to the underside and through a second through hole from the underside to the support surface. Further preferably, the body can be released and resecured to the loop at the underside by corresponding hook-and-loop features on the underside and the loop. Preferably, the suspender includes a suspension connector secured to the loop along the length, and the suspension connector is adapted to connect to the support structure.
