Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a ring-type stand is used, then the stand can be attached to the back of the device, but it cannot provide stable support and adjustable viewing angles for larger devices like tablets
Solution Approach 1:
The stand employs a dynamic telescopic structure with multiple segments that can extend and retract. When extended, the stand provides sufficient length and stability for larger devices like tablets, and when retracted, it maintains a compact profile. This dynamic adjustment capability allows the same stand to adapt to different device sizes while maintaining stability.
Solution Approach 2:
The stand is divided into multiple telescopic segments that can move relative to each other. This segmentation allows the stand to adjust its overall length and configuration, providing stable support for various device sizes. The segmented structure also enables the stand to achieve different viewing angles by adjusting the relative positions of the segments.
2Adaptability or versatility
If the stand is extended to provide stable support for tablets, then support capability improves, but the stand cannot maintain a sleek appearance and compact profile
Solution Approach 1:
The stand features a telescopic mechanism that allows it to dynamically change its length. When not in use, the stand retracts to a compact size that maintains a sleek appearance. When needed, especially for larger devices, the stand extends to provide the necessary support length. This dynamic transformation resolves the conflict between maintaining a compact profile and providing adequate support.
Solution Approach 2:
The telescopic segments of the stand are nested within each other when retracted, similar to a nested doll structure. This nesting allows the stand to minimize its protruding profile when not in use, maintaining a sleek appearance. When extended, the segments unfold to provide the required support length for various devices.
3Volume of moving object
If a pivoting structure is added to fold up the ring stand, then the stand can be compacted, but the thickness of the whole stand increases
Solution Approach 1:
The stand is segmented into multiple telescopic sections that can collapse into each other. This segmentation allows the stand to reduce its overall volume significantly when compacted, without requiring thick pivoting mechanisms. The segments slide into one another, achieving compact storage while maintaining a thin profile.
Solution Approach 2:
The stand uses a dynamic telescopic mechanism rather than a rigid pivoting structure. The segments can slide in and out smoothly, allowing the stand to transition between extended and compact states. This dynamic design achieves compactness without adding significant thickness, as the segments nest within each other rather than requiring external pivoting space.
4Adaptability or versatility
If the stand structure is made complex to provide adjustable viewing angles, then versatility improves, but the device complexity increases
Solution Approach 1:
The stand uses a dynamic telescopic mechanism where segments can extend and retract independently. By controlling the extension of different segments, the stand can achieve various viewing angles and support configurations. This dynamic adjustment is achieved through a relatively simple telescopic structure rather than complex mechanical linkages, maintaining ease of manufacture while providing versatility.
Solution Approach 2:
The telescopic stand structure serves multiple functions: it provides stable support for different device sizes, enables adjustable viewing angles, and maintains a compact profile when retracted. This multi-functional design achieves versatility without requiring separate mechanisms for each function, as the telescopic structure inherently provides all these capabilities through its extension and retraction movements.

Implementation Method 1
a lifting device (13) between the first plate (11) and the second plate (12)... an elastic sheet (131) having a first end portion (1311) and a second end portion (1312)... The first end portion (1311) is formed on an inner side of the free end portion (112) of the first plate (11), and the second end portion (1312) is formed on an inner side of the free end portion (122) of the second plate (12)

AI summary
The invention relates to a stand for hand-held device and a protective case comprising the stand. The stand comprises a first plate, a second plate and a lifting device between the first plate and the second plate. The inner end of the first plate and the inner end of the second plate are pivoted with each other to form a pivoting portion. The lifting device controls the free end portion of the first plate and the free end portion of the second plate to be close to or away from each other. The lifting device comprises a limiting device and an elastic sheet, thereby when one end of the elastic sheet moves along the length direction of the second plate, and construes a first displacement relative to the pivoting portion, the free end portion of the first plate is driven up to form a second displacement relative to the free end portion of the second plate.
