Solution Overview

Problem

Existing computing devices with hinges lack a mechanism to securely and aesthetically integrate hinge covers that also contribute to structural stability and controlled sequential rotation, leading to instability and potential tipping during use.

Innovation Solution

A covered, sequentially rotating multi-axis hinge assembly (CSRMA) with integrated hinge covers that function both as structural elements and protective covers, utilizing friction engines and timing elements to control the sequential rotation of multiple pivots, increasing the device's footprint for stability and preventing accidental damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If traditional hinge mechanisms are used, then the device can rotate, but the device lacks stability and may tip during use

Engineering Contradiction:
Improvedevice stabilityVSAvoidhinge mechanism complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The hinge assembly is divided into multiple independent pivot assemblies (first pivot assembly, second pivot assembly, third pivot assembly) that can rotate sequentially. Each pivot assembly is a separate module with its own rotation axis and cover, allowing the system to achieve stability through distributed pivots while maintaining manageable complexity through modular design.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a temporal dimension to the rotation process by implementing sequential rotation control. The timing elements ensure that pivots rotate in a specific order (first pivot, then second, then third), transforming a potentially unstable simultaneous multi-axis rotation into a controlled sequential process that maintains stability throughout the motion.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Object-affected harmful factors

If hinge covers are added for protection, then internal components are protected, but the hinge mechanism becomes more complex

Engineering Contradiction:
Improveprotection of internal componentsVSAvoidhinge mechanism complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The cover is merged with the pivot assembly structure itself. Each pivot assembly includes a cover that is integrated into the assembly rather than being a separate protective component. This merging provides protection while avoiding the complexity of additional separate cover mechanisms.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The timing elements serve multiple functions: they control the sequential rotation of pivots and simultaneously act as structural components of the hinge assembly. This multi-functionality reduces the need for separate control mechanisms, thereby protecting internal components without proportionally increasing complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Area of stationary object

If multiple pivots are used to increase stability, then the device footprint increases, but the hinge mechanism becomes more complex

Engineering Contradiction:
Improvedevice footprintVSAvoidhinge mechanism complexity
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The multiple pivot assemblies are arranged in a nested or compact configuration where the first, second, and third pivot assemblies are positioned close together along the hinge axis. This nesting allows the mechanism to provide a distributed footprint for stability while maintaining a compact overall structure that doesn't excessively increase device complexity.

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

The description relates to devices, such as computing devices that have hinged portions. One example can include a first portion and a second portion. This example can also include a multi-pivot hinge unit rotatably securing the first and second portions. This example can further include a covered sequentially rotating multi-pivot hinge assembly (734) rotatably securing the first portion and the second portion in a manner that extends a footprint of the computing device as the first portion is rotated away from the second portion.
