Solution Overview

Problem

Existing vehicle mount camera brackets are difficult to miniaturize in the front-back direction and cannot completely prevent rattling due to the need for a plate spring to push from the rear side of the camera.

Innovation Solution

A bracket with a base portion fixed to the window glass and an engagement piece that allows sliding movement of the camera using elastic deformation, eliminating the need for a rear-facing component and spring, thereby minimizing size and preventing rattling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a plate spring is used to push from the rear side of the camera, then the camera can be held in position, but the bracket size in the front-back direction increases and rattling cannot be completely prevented

Engineering Contradiction:
Improvestability of camera attachmentVSAvoidbracket length in front-back direction
Core Design Contradiction:
ReliabilityVSLength of moving object

Solution Approach 1:

The invention extracts the spring mechanism from the bracket structure entirely. Instead of using a plate spring to push from the rear, the engagement piece directly engages the rear end of the camera body through elastic deformation of its own material, eliminating the need for a separate spring component and reducing the bracket's front-back length.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention merges the engagement function and elastic pushing function into a single integrated engagement piece. The elastic deformation capability is built into the engagement piece itself rather than being provided by a separate spring, combining multiple functions into one component.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If a plate spring is used to push from the rear side of the camera, then the camera can be held in position, but the bracket structure becomes more complex

Engineering Contradiction:
Improvestability of camera attachmentVSAvoidbracket structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The spring component is extracted from the bracket assembly, simplifying the overall structure. The engagement piece alone provides both engagement and elastic retention functions without requiring additional spring components.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Multiple functions (engagement and elastic retention) are merged into the single engagement piece, reducing the number of components and simplifying the bracket structure while maintaining reliable camera attachment.

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If the engagement piece has sufficient elastic recovery force, then the camera can be securely engaged, but the engagement piece may deform excessively during engagement

Engineering Contradiction:
Improveengagement securityVSAvoidengagement piece deformation
Core Design Contradiction:
ReliabilityVSShape

Solution Approach 1:

The engagement piece has different local properties: the engagement portion is designed with higher rigidity to maintain shape during engagement, while the connection portion to the base has greater elasticity to provide secure retention. This local differentiation allows secure engagement without excessive overall deformation.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The engagement piece is pre-formed with a specific shape and elastic properties that allow it to deform in a controlled manner during engagement. The preliminary design of its geometry ensures that elastic recovery occurs within acceptable deformation limits while still providing secure camera retention.

Inventive Principle:
Principle #10Preliminary action

AI summary

A bracket includes a base portion arranged to be fixed to a face inside the window glass, and an engagement piece, an engagement portion thereof engaging an end of the vehicle mount camera located at a rear side in a sliding movement by a sliding operation of the vehicle mount camera. The engagement piece includes a fixed end integrated with the base portion, and a free end arranged with a space relative to the fixed end in a vehicle front-rear direction, the engagement portion being provided at the free end so that the sliding operation of the vehicle mount camera is made by an elastic deformation of the engagement piece through an abutment of the engagement portion to the vehicle mount camera, and an engagement of the engagement portion is made by an elastic recovery of the engagement piece at an end position of the sliding operation.
