Solution Overview

Problem

Conventional handles are limited in usage occasions as they require a fixed connection to a display screen and can only be operated when facing the screen, restricting their application range.

Innovation Solution

A rotating assembly comprising a rotary shaft with tenons and a position-limiting switch, allowing the handle's body portion to flip relative to the gripping portions, enabling operation in various environments and expanding usage occasions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the body portion and gripping portions are fixedly connected, then the handle structure is simple and stable, but the handle can only be used in limited occasions requiring a display screen

Engineering Contradiction:
Improveusage occasionsVSAvoidhandle structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies the dynamics principle by transforming the fixed connection between the body portion and gripping portions into a rotatable connection. The rotating assembly allows the body portion to rotate relative to the gripping portions, enabling the handle to be used in different orientations and occasions without requiring a display screen, thus improving adaptability while maintaining manageable structural complexity through a well-defined rotation mechanism

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If the handle is connected to a display screen, then the handle can achieve corresponding functions through control keys, but the user must face the screen which greatly limits operation occasions

Engineering Contradiction:
Improveoperation environmentsVSAvoidoperation convenience
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The rotating assembly enables the handle to dynamically adjust its orientation, allowing users to operate the handle in various environments without being constrained to face a display screen. The rotation mechanism maintains control key functionality while freeing the user from fixed positioning requirements

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The rotating assembly adds multi-functionality to the handle by enabling it to operate independently of a display screen in many occasions, while still maintaining its original control key functions when connected to a screen, thus expanding the handle's operational universality

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

3Adaptability or versatility

If the rotary shaft rotates freely, then the body portion can flip to various positions, but the position-limiting switch and second tenon clamping mechanism is needed to prevent excessive rotation

Engineering Contradiction:
Improverotation flexibilityVSAvoidposition-limiting mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies parameter changes by using a position-limiting switch that detects the rotational position of the rotary shaft and activates a clamping mechanism only when necessary. This allows the rotary shaft to rotate freely within normal operational ranges while preventing excessive rotation, balancing rotation flexibility with controlled limitation through dynamic parameter monitoring

Inventive Principle:
Principle #35Parameter changes

AI summary

A rotating assembly comprises a rotary shaft, an accommodating body and a position-limiting switch. An outer wall of the rotary shaft includes a first tenon and a second tenon. The accommodating body includes a matching hole for the first tenon to insert and rotate therein. An inner wall of the matching hole includes a convex rib. By rotating the rotary shaft, a side wall of the first tenon and a side wall of the convex rib butt against or separate from each other, so that in an axial direction of the rotary shaft, the rotary shaft is fixed or movable relative to the accommodating body. When the side wall of the first tenon and the side wall of the convex rib butt against each other, the position-limiting switch and the second tenon are clamped together to prevent the rotary shaft from rotating relative to the accommodating body.
