Innovation Solution

A handle device with a movable rotating shaft that translates and rotates, allowing deployment at a smaller angle, ensuring safety and efficient space utilization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the handle is deployed outwardly to provide sufficient room for operator access, then user accessibility is improved, but safety hazards increase and space requirements increase

Engineering Contradiction:

Improveuser accessibilityVSAvoidsafety hazards

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The handle device employs dynamic deployment where the handle body translates along the door surface and rotates to a predetermined angle rather than fixed outward deployment. This dynamic mechanism allows the handle to achieve sufficient projection distance for user access while controlling the deployment angle to minimize safety hazards. The translating and rotating motion enables optimized positioning at each operational stage.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The invention changes the deployment parameters by introducing both translation distance and rotation angle as controllable variables. The handle body translates by a first distance along the door surface and then rotates by a predetermined angle, rather than simple radial deployment. This parameter optimization allows achieving user accessibility while controlling outward projection to reduce safety risks.

Inventive Principle:

Principle #35Parameter changes

2Ease of operation

If the handle is deployed outwardly to provide sufficient room for operator access, then user accessibility is improved, but the space required for component arrangement increases

Engineering Contradiction:

Improveuser accessibilityVSAvoidcomponent arrangement space

Core Design Contradiction:

Ease of operationVSArea of stationary object

Solution Approach 1:

The handle device employs dynamic deployment where the handle body translates along the door surface and rotates to a predetermined angle rather than fixed outward deployment. This dynamic mechanism allows the handle to achieve sufficient projection distance for user access while controlling the deployment angle to minimize safety hazards. The translating and rotating motion enables optimized positioning at each operational stage.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The invention transitions from simple radial deployment to a two-dimensional motion path combining translation along the door surface and rotation. This dimensional change allows the handle to achieve the necessary projection distance for user access while utilizing the door surface space more efficiently, thereby reducing the overall space required for component arrangement.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Ease of operation

If the handle is deployed outwardly, then user access is enabled, but the deployment distance becomes excessive

Engineering Contradiction:

Improveuser accessVSAvoiddeployment distance

Core Design Contradiction:

Ease of operationVSLength of moving object

Solution Approach 1:

The invention changes the deployment parameters by introducing both translation distance and rotation angle as controllable variables. The handle body translates by a first distance along the door surface and then rotates by a predetermined angle, rather than simple radial deployment. This parameter optimization allows achieving user accessibility while controlling outward projection to reduce safety risks.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The deployment motion is segmented into two distinct stages: first translation along the door surface by a first distance, then rotation by a predetermined angle. This segmentation allows precise control over the total deployment distance and projection angle, achieving sufficient user access while avoiding excessive outward extension.

Inventive Principle:

Principle #1Segmentation

AI summary

A handle device and a vehicle includes a handle base, a handle, a first pushing member and a second pushing member. The handle comprises a handle body, a handle shaft, and an operating member, the operating member extends from the handle body, the handle body is translatably and rotatably mounted on the handle base relative to the handle base by means of the handle shaft, so as to be movable between a retracted position and a deployed position; the first pushing member is mounted translatably in a first direction on the handle base and operatively coupled with the handle body; and the second pushing member is configured to translate in a second direction different from the first direction under the drive of a driver, wherein the second pushing member is configured to operatively engage with the first pushing member and the operating member when translating in the second direction toward the first pushing member, to push the handle body to translate in the first direction by means of the first pushing member, and to push the handle body to rotate by means of the operating member, such that the handle body is moved from the retracted position to the deployed position. The handle device of the present disclosure has a movable rotating shaft, facilitating the handle to be deployed at a relatively small angle to the desired deployed position.
