Solution Overview

Problem

The user experience is poor due to the umbrella handle of existing in-vehicle sunshades easily bumping against the steering wheel or display screen, causing damage.

Innovation Solution

An in-vehicle sunshade with an umbrella handle that can rotate and bend, foldable ribs, and an umbrella fabric, allowing the handle to adjust its direction to avoid collisions with vehicle components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the umbrella handle is fixed in position, then the structure is simple and stable, but the handle easily bumps against the steering wheel or display screen causing damage

Engineering Contradiction:
Improvedamage preventionVSAvoidhandle structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The umbrella handle is transformed from a fixed structure to a dynamic one, enabling rotation and bending movements. The handle can rotate around the mounting end and bend at intermediate points, allowing it to dynamically adjust its position to avoid colliding with the steering wheel or display screen while maintaining structural simplicity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The handle structure is divided into multiple segments: a mounting end fixed to the windshield, a handle end with rotating capability, and intermediate sections with bending capability. This segmentation allows each part to perform specific functions (rotation, bending, support) independently, resolving the contradiction between reliability and complexity.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If the umbrella handle can rotate and bend, then it can avoid bumping against vehicle components, but the structure becomes more complex

Engineering Contradiction:
Improvehandle positioning flexibilityVSAvoidhandle mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The handle incorporates dynamic elements including a rotating joint at the mounting end and bending sections along its length. These dynamic features enable the handle to adapt its position and orientation to avoid obstacles while keeping the overall mechanism simple through passive mechanical design rather than active control systems.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The handle's rotation and bending capabilities are designed to function automatically based on physical interactions (e.g., gentle contact with obstacles triggers rotation or bending). This self-service mechanism achieves adaptability without requiring complex sensors, controllers, or power sources, thus maintaining structural simplicity.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If the handle end rotates relative to the mounting end, then the direction can be adjusted to avoid collisions, but the connection structure becomes more complex

Engineering Contradiction:
Improvedirection adjustmentVSAvoidconnection structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The connection between the handle end and mounting end incorporates a rotating joint that allows directional adjustment. This dynamic connection enables easy rotation to change the handle's pointing direction while maintaining a simple mechanical joint structure without complex actuators or control systems.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The rotating connection is designed to respond automatically to user input or environmental factors (such as gentle pushes or magnetic alignment). The handle can be manually rotated to the desired direction and will maintain its position without requiring complex locking mechanisms or power sources, achieving ease of operation with minimal structural complexity.

Inventive Principle:
Principle #25Self-service

AI summary

The present disclosure relates to an in-vehicle sunshade, including an umbrella handle, foldable ribs, and an umbrella fabric. The umbrella handle has a mounting end and a handle end opposite to each other in an axial direction thereof. The handle end is capable of rotating and bending relative to the mounting end to adjust the direction of the handle end. The foldable ribs are connected to the mounting end of the umbrella handle. According to the in-vehicle sunshade provided by the present disclosure, a user can adjust the placement location of the handle end according to positions of a steering wheel and a display in a vehicle. The umbrella handle will not bump against the steering wheel and the display in the vehicle, and the steering wheel and the display will not be damaged, so that the user experience is good.
