Hands-Free Portable Work Surface with Shoulder Strap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable work surfaces, such as clipboards and modern devices like tablet computers, require users to hold them with one hand while using the other hand for writing or annotation, leading to discomfort due to lack of hands-free operation.
Innovation Solution
A hands-free, portable work surface design featuring a rigid substrate with a strap routed between diagonally opposed corners, forming a loop with adjustable buckles, allowing the surface to be worn on the body, enabling hands-free use by securing it against the user's person.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a clipboard or tablet computer is used as a portable work surface, then portability and functionality are improved, but the user must hold it with one hand while writing with the other, causing discomfort and fatigue
Solution Approach 1:
A strap is introduced as an intermediary element between the work surface and the user's body. The strap is attached to the work surface and worn over the shoulder, acting as a mediator that transfers the support function from the user's hand to the user's body, enabling hands-free operation while maintaining portability
Solution Approach 2:
The support mechanism is shifted from a horizontal hand-held position to a vertical body-worn position. By routing the strap over the shoulder and attaching it to the work surface, the device is repositioned in three-dimensional space, allowing the work surface to rest against the user's torso rather than being held in the hand
2Duration of action of moving object
If a strap is attached to the top of the clipboard to prevent it from being put down, then continuous use is improved, but the user still must hold the clipboard while actively using it
Solution Approach 1:
The strap serves as a mechanical intermediary that connects the work surface to the user's shoulder. This intermediary structure bears the weight of the work surface, freeing the user's hands from the task of holding it while allowing continuous access to the work surface during active use

AI summary
A hands-free portable work surface includes a rigid work surface substrate and a strap connected thereto. The strap extends away from the work surface at two points along a perimeter thereof, and is routed along the perimeter of the work surface between the two connection points.
