Transforming Laptop Case with Hinge and Ergonomic Strap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulty in balancing and operating laptop computers while carrying them, as they often need to hold the device with one hand to use it with the other, especially in mobile situations.
Innovation Solution
A laptop carrying case that transforms into a desktop setup, featuring a hinge structure and ergonomic pad, allowing the laptop to be securely positioned horizontally for use and easily carried when needed, with elastic bands for securing the device and a strap system for neck support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a laptop is carried using a traditional carrying case, then the laptop is protected and portable, but the user must balance the laptop on one hand while operating it with the other hand
Solution Approach 1:
The carrying case incorporates a hinge structure that allows dynamic transformation between a closed carrying configuration and an open desktop configuration. The hinge enables the case to adapt its form factor based on usage needs, providing stability for hands-free operation when open and portability when closed.
Solution Approach 2:
The carrying case is designed to serve multiple functions: it acts as a protective case for transport, a stable support structure for hands-free use, and a collapsible framework that folds into a compact form when not in use. This multi-functionality eliminates the need for separate carrying and desktop solutions.
2Ease of operation
If a bulky harness is used to support the laptop around the back and shoulders, then the laptop can be carried hands-free, but the structure becomes heavy and complex
Solution Approach 1:
The support structure is divided into separate functional components: a lightweight strap for wearing, a hinge mechanism for positioning, and a case body for support. This segmentation allows each component to be optimized independently, resulting in a lighter overall system compared to a monolithic harness.
Solution Approach 2:
The hinge structure acts as an intermediary mechanism between the strap and the case, providing the necessary support and positioning without requiring a bulky harness. The hinge mediates the force transmission and structural support, enabling a lightweight design.
3Stability of the object's composition
If the carrying case structure is made rigid to support the laptop horizontally, then the laptop can be used as a desktop, but the structure becomes bulky and heavy
Solution Approach 1:
The case structure transitions from a rigid, bulky form when closed to a compact, stable configuration when open. The hinge enables the structure to be rigid during use for stability, then collapse into a compact form for portability, eliminating the need for permanent bulkiness.
Solution Approach 2:
When the case is closed, the inner components nest within the outer shell, creating a compact protective form. When opened, the structure expands to provide a stable desktop surface. This nesting capability allows the same structure to be both compact and stable at different states.
4Ease of operation
If a traditional neck strap is used, then the laptop can be carried around the neck, but the load is concentrated on the back of the neck causing discomfort
Solution Approach 1:
The strap incorporates an ergonomic pad with specific local properties (cushioning, contouring) at the contact point with the neck. This localized quality improvement distributes the load more comfortably on the trapezius muscles rather than concentrating it on the back of the neck, addressing the discomfort issue without affecting overall portability.

AI summary
A laptop computer carrying case transforms into a desktop for use of a laptop or similar electronic device having a keyboard and a hingeably openable display. The laptop key board is held by bands in the lower portion of the case and the display is held in the top section of the case. Hinge structures are provided on the left and right sidewalls of the bottom section of the case. When the hinge structures are pivotally angularly separated, the bottom section containing the keyboard will be substantially horizontal enabling use of the laptop in a standing or mobile position. When the laptop is not being used, the case may be closed and the hinge structures closed with the laptop being carried by the strap over the shoulder. The hinge structure is provided with structure for limiting the amount by which the arms of the hinge may be pivotally angularly separated thereby providing stability to the laptop case in the desk top position. Detent means is provided to hold the arms of the hinge structure in aligned position when the case is being used to carry the laptop.
