Tablet Case With Retractable Legs for Adjustable Hands-Free Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional tablet cases do not provide protection for both the device screen and frame while allowing the device to stand on a flat surface, nor do they alleviate 'tablet neck pain' associated with long-term use, as they fail to offer adjustable height options.
Innovation Solution
A self-standing tablet case with an extendable and collapsible leg base that securely covers the device's edges and back, featuring retractable legs with a folding base and adjustable legs for customizable height, allowing the device to stand upright and angled on a surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional device cases are used to protect the device screen and frame, then device protection is improved, but the ability to stand on a flat surface handsfree is lost
Solution Approach 1:
The patent combines the protective case function with a standing mechanism by integrating a retractable leg assembly directly into the case structure. The case body (202) incorporates a housing (204) that contains the leg assembly (206), merging protection and positioning functions into a single integrated unit that provides both device protection and handsfree viewing capability
Solution Approach 2:
The patent employs a dynamic, adjustable leg assembly that can extend and retract to different positions. The leg assembly (206) includes an extendable portion (208) that can be adjusted to various lengths, allowing the case to adapt between a compact protected state and an extended standing state, providing both protection and handsfree viewing as needed
2Ease of operation
If fixed-height stands are used to allow handsfree viewing, then viewing capability is improved, but the ability to adjust device height is lost
Solution Approach 1:
The leg assembly (206) is designed with dynamic adjustability, featuring an extendable portion (208) that can be extended or retracted to different positions. This allows the standing height to be adjusted dynamically based on user needs, enabling both handsfree viewing and customizable height adaptation for different viewing preferences and ergonomics
Solution Approach 2:
The leg assembly is segmented into multiple components including a first leg portion (210), an extendable portion (208), and a second leg portion (212). This segmentation allows independent adjustment of each segment to achieve various height configurations, providing versatility in positioning the device at optimal viewing heights for different users and situations
