Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The increased area of brackets used to attach information acquisition devices to vehicle windshields leads to a larger restoring force, causing the brackets to come off or shift position, resulting in fitting failures due to the curved shape of the windshield.

Innovation Solution

A bracket with a mesh-like coupling region made of resin, featuring flexible regions and elongated holes, allows for flexible coupling and adherence to the curved windshield surface, reducing the restoring force and maintaining accurate positioning of the devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the area of the bracket is increased to attach more information acquisition devices, then the number of devices that can be mounted increases, but the restoring force acting on the bracket becomes larger causing detachment or position shift

Engineering Contradiction:

Improvenumber of information acquisition devicesVSAvoidbracket attachment stability

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The bracket is divided into multiple regions (first region, second region, third region) that can independently adapt to the curved windshield surface. Each region can flexibly deform to follow the surface curvature, reducing the overall restoring force while maintaining multiple mounting positions for information acquisition devices.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The bracket incorporates a flexible coupling region with mesh-like structure that allows dynamic deformation. This coupling region enables the bracket to adapt its shape to the curved windshield surface, reducing the restoring force that would otherwise cause detachment or position shift of larger-area brackets.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If the area of the bracket is increased to accommodate more devices, then the functional capability increases, but the restoring force causes position shift of fixing members

Engineering Contradiction:

Improvedevice mounting capabilityVSAvoidfixing member position accuracy

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The bracket is segmented into multiple independent regions that can be positioned and fixed separately. Each region maintains its position independently through the flexible coupling, ensuring that fixing members in different regions remain accurately positioned despite the overall bracket adapting to the curved surface.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The coupling region employs a mesh-like flexible structure that allows the bracket to conform to the curved windshield surface. This flexibility enables the bracket to adapt to the surface geometry without causing position shifts in the fixing members, as the flexible structure absorbs the deformation stresses.

Inventive Principle:

Principle #30Flexible shells and thin films

3Strength

If a rigid bracket structure is used to maintain positioning accuracy, then the structural strength is sufficient, but the restoring force on curved surfaces causes detachment

Engineering Contradiction:

Improvebracket structural strengthVSAvoidattachment stability on curved surface

Core Design Contradiction:

StrengthVSReliability

Solution Approach 1:

The bracket is divided into multiple rigid regions connected by flexible coupling regions. Each rigid region maintains sufficient structural strength for mounting devices, while the flexible coupling regions allow the overall structure to adapt to the curved windshield surface, reducing the restoring force that would cause detachment.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different parts of the bracket have different mechanical properties: the regions for mounting devices maintain rigidity and strength, while the coupling regions between them are made flexible with a mesh-like structure. This local differentiation allows the bracket to simultaneously provide structural strength for device mounting and flexibility for adapting to curved surfaces.

Inventive Principle:

Principle #3Local quality
