Protective Casing for Tablet Computer with Damping Hinge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current two-in-one computers face issues with stability in notebook mode due to a low support point and high center of gravity, poor portability and thinness in tablet mode, low external cleanliness, and aesthetic concerns, along with inadequate protection of the tablet host's rear surface.
Innovation Solution
A protective case design that includes a first and second support plate, a cover plate, and a damping rotating shaft, allowing the tablet computer to be supported by an A-frame in notebook mode and easily converted to tablet mode, with the damping rotating shaft providing stability and damping effect without additional damping structures, and maintaining cleanliness and uniformity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a supporting structure is added to the tablet host to improve stability in notebook mode, then stability is improved, but the structural space increases and the device becomes heavier and thicker
Solution Approach 1:
The protective case is divided into separate functional components: a cover plate for protection, and an A-frame structure formed by the first and second support plates for stability. This segmentation allows each component to perform its specific function efficiently without requiring additional space within the tablet host.
Solution Approach 2:
The protective case acts as an intermediary structure between the tablet host and the external environment. It provides the supporting function externally rather than requiring internal modifications to the tablet host, thus avoiding occupation of structural space within the device.
2Stability of the object's composition
If a built-in support structure is integrated into the tablet host to improve stability, then stability is improved, but the tablet host requires relatively large structural space and experience of lightness and thinness is compromised
Solution Approach 1:
The support function is segmented from the tablet host and implemented in the protective case. The first support plate and second support plate form an A-frame structure that provides stability without adding thickness to the tablet host itself.
Solution Approach 2:
The supporting function is extracted from the tablet host and implemented in the external protective case. This allows the tablet host to remain thin and light while still providing stability when needed through the detachable protective case.
3Object-affected harmful factors
If additional protection structures are added to the tablet host to protect the rear surface, then protection is improved, but the external cleanliness and uniformity are compromised
Solution Approach 1:
The protective function and the supporting function are merged into a single integrated protective case structure. The cover plate provides protection for the rear surface while the first and second support plates provide stability, eliminating the need for separate protection structures that would compromise appearance.
Solution Approach 2:
The protective case serves multiple functions: it protects the rear surface of the tablet host through the cover plate, provides stability through the A-frame structure, and maintains external cleanliness by providing a uniform aesthetic appearance without additional protruding structures.
4Productivity
If a keyboard is integrated with the display screen to form a two-in-one computer, then productivity is improved, but portability and thinness in tablet mode are compromised
Solution Approach 1:
The protective case is designed to be dynamically configurable - it can be attached to provide notebook mode stability when productivity is needed, or detached when portability and thinness are prioritized in tablet mode. This dynamic adaptability resolves the contradiction between productivity and portability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The protective case enhances stability in notebook mode, improves portability and thinness in tablet mode, maintains external cleanliness, and provides effective protection to the tablet computer, addressing the limitations of existing two-in-one computers.
Implementation Method 1
The display screen is hinged to the keyboard by using a damping rotating shaft. The damping rotating shaft may enable the display screen to rotate by 0° to 360° relative to the keyboard.
