Solution Overview

Problem

Existing handheld device stands, such as the 'ring-type' and flexible strap designs, fail to provide adequate support and adjustability for optimal viewing angles, are not compact when folded, and often compromise the appearance and durability of mobile phones and tablets.

Innovation Solution

A collapsible stand with a first and second plate, connected by a lifting device featuring an elastic sheet and limiting mechanism, allowing for adjustable positioning and compact folding, ensuring the stand is thin and aesthetically pleasing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a ring-type stand is used, then the stand can be attached to the back of the device, but it cannot provide proper viewing angle and standing position

Engineering Contradiction:
Improveattachment convenienceVSAvoidviewing angle adjustment
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The stand employs a dynamic linkage mechanism with multiple joints that allows the support surface to be adjusted to different angles and positions. The connected segments can rotate relative to each other, enabling the stand to adapt to various viewing angles and device orientations, resolving the contradiction between simple attachment and versatile positioning.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The stand is divided into multiple connected segments or plates that can move independently relative to each other. This segmentation allows each part to contribute to the overall positioning capability, enabling both easy attachment and flexible angle adjustment simultaneously.

Inventive Principle:
Principle #1Segmentation

2Reliability

If a ring-type stand is used, then the stand can support the device, but it cannot be compact when folded

Engineering Contradiction:
Improvesupport stabilityVSAvoidfolded size
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The stand segments are designed to nest within each other when folded, with each plate or segment fitting into the structure of the previous one. This nesting arrangement maintains support stability when deployed while minimizing the overall volume when folded, resolving the contradiction between reliability and compactness.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The collapsible linkage mechanism allows the stand to transition between an extended stable configuration for support and a compact folded configuration for storage, dynamically adapting its structure to meet different spatial requirements while maintaining functional integrity.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If a metal ring stand with pivoting structure is used, then the stand can fold up, but the thickness cannot be thin

Engineering Contradiction:
Improvefolding capabilityVSAvoidstand thickness
Core Design Contradiction:
Adaptability or versatilityVSLength of stationary object

Solution Approach 1:

The stand utilizes thin plate structures connected by flexible joints instead of bulky metal rings. These thin plates can bend and rotate relative to each other, providing folding capability while maintaining a thin overall profile, thus resolving the contradiction between adaptability and thickness.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The thin plate structure incorporates dynamic hinge joints that enable folding motion without requiring additional thickness. The joints are designed to allow rotation between thin plates, maintaining a slim profile in both folded and extended states while preserving folding functionality.

Inventive Principle:
Principle #15Dynamics

4Adaptability or versatility

If an irregular asymmetric stand shape is used, then the stand can function, but it is not good-looking

Engineering Contradiction:
Improvefunctional capabilityVSAvoidaesthetic appearance
Core Design Contradiction:
Adaptability or versatilityVSShape

Solution Approach 1:

The stand employs asymmetric plate shapes and joint configurations that are optimized for both functionality and aesthetics. The asymmetric design allows the stand to achieve proper support geometry while the plates themselves can be shaped to provide visual appeal, resolving the contradiction between functional capability and aesthetic appearance.

Inventive Principle:
Principle #4Asymmetry

Solution Approach 2:

Different parts of the stand have different shapes and properties optimized for their specific functions. The visible surfaces can be designed with aesthetically pleasing forms, while the structural joints and connection points are optimized for mechanical functionality, allowing both good appearance and functional capability to coexist.

Inventive Principle:
Principle #3Local quality

AI summary

The invention relates to a stand (10, 20, 30, 40, 50, 60) for hand-held device (7) and a protective case (8, 9) comprising the stand. The stand comprises a first plate (11, 21, 31, 41, 51, 61), a second plate (12, 22, 32, 42, 52, 62) and a lifting device (13, 23, 33, 43, 53) 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 (P1, P2, P3, P4, P5, P6). 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 (131, 231, 331, 431, 531, 631), 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.
