Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If the stand is positioned near the middle area of the electronic equipment accessory, then the support stability is improved, but the magnetic attraction structure and wireless charging coils are interfered with

Engineering Contradiction:

Improvesupport stabilityVSAvoidinterference with magnetic attraction structure and wireless charging coils

Core Design Contradiction:

Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The patent changes the spatial arrangement by introducing an inclined shaft that extends from the bottom edge toward the middle area at a specific angle (45-75 degrees). This dimensional change allows the stand to achieve both stability and non-interference with magnetic components by positioning it along an inclined path rather than a horizontal or vertical arrangement

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The stand is positioned asymmetrically near the bottom edge rather than symmetrically in the middle area. The inclined shaft creates an asymmetric configuration that provides stable support while deliberately avoiding the central region where magnetic attraction structures and wireless charging coils are located

Inventive Principle:

Principle #4Asymmetry

2Object-affected harmful factors

If the stand is positioned near the edges of the mobile phones, then the magnetic attraction structure and wireless charging coils are not interfered with, but the support stability deteriorates

Engineering Contradiction:

Improveinterference with magnetic attraction structure and wireless charging coilsVSAvoidsupport stability

Core Design Contradiction:

Object-affected harmful factorsVSStability of the object's composition

Solution Approach 1:

The inclined shaft introduces a third-dimensional angle to the stand configuration, extending from the bottom edge upward and inward at 45-75 degrees. This dimensional approach allows the stand to leverage the bottom edge position for non-interference while the inclined geometry provides the mechanical stability normally associated with central positioning

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Stability of the object's composition

If the rotating device is positioned between the magnetic charging structure and the bottom edge, then both support stability and non-interference are achieved, but the device complexity increases

Engineering Contradiction:

Improvesupport stabilityVSAvoidrotating device structure

Core Design Contradiction:

Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The patent merges multiple functions into the inclined shaft structure: it serves as both the rotational axis and the structural support element. The shaft combines the rotational mechanism with the positioning function, eliminating the need for separate complex assemblies and reducing overall device complexity while achieving the desired positioning between the magnetic charging structure and bottom edge

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A rotating device and an electronic equipment accessory are provided. The rotating device includes a first connecting member and a second connecting member rotatable about a rotation axis relative to the first connecting member. An angle formed between the rotation axis and a length direction of the rotating device is acute such that the second connecting member can move upwards when rotating with respect to the first connecting member. Therefore, when the rotating device is applied to an electronic equipment accessory which is mounted on electronic equipment, the rotating device acting as a stand can be arranged between a magnetic charging structure of electronic equipment and a bottom edge of the electronic equipment, such that the rotating device will not shield the magnetic charging structure. The rotating device can act as a stand with a good support effect due to existing of the acute angle.
