Solution Overview

Problem

Existing device fixing brackets for vehicles, such as kick scooters and tricycles, are large, inconvenient to use, and pose safety hazards due to their manual operation and protruding design.

Innovation Solution

A device fixing bracket with a first and second member that can move relative to each other, equipped with clamping portions and a pull-back structure, allowing for autonomous clamping and retraction of the bracket to reduce volume and improve aesthetics and safety.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a device fixing bracket is mounted on a handlebar and protrudes from the handlebar, then the device can be fixed and held stable, but the bracket becomes large in size and not appealing, and may cause safety hazards

Engineering Contradiction:

Improvestability of device fixationVSAvoidsize of device fixing bracket

Core Design Contradiction:

ReliabilityVSVolume of moving object

Solution Approach 1:

The device fixing bracket is designed with a nested structure where the second member can be received within the first member when retracted, and extended outward when needed for device fixation. This nesting mechanism allows the bracket to maintain a compact profile during normal vehicle use while providing full functionality when required.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Reliability

If a device fixing bracket protrudes from the handlebar, then the device can be clamped securely, but the bracket is large in size and poses safety hazards

Engineering Contradiction:

Improvesecurity of device clampingVSAvoidsafety hazards

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The device fixing bracket transitions from a static protruding structure to a dynamic retractable mechanism. The second member can extend outward to provide secure device clamping when needed, then retract into the first member to eliminate safety hazards during normal vehicle operation, making the vehicle profile sleeker and safer.

Inventive Principle:

Principle #15Dynamics

3Reliability

If a device fixing bracket is manually opened and closed, then the device can be secured, but the operation is inconvenient and may cause safety hazards

Engineering Contradiction:

Improvedevice securing capabilityVSAvoidconvenience of bracket operation

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The device fixing bracket incorporates a self-actuating mechanism where the relative movement between the first and second members automatically triggers the clamping action through connected clamping portions. The spring assembly provides automatic engagement force, eliminating the need for manual opening and closing operations while ensuring reliable device securing.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The spring assembly is pre-loaded to store elastic potential energy that automatically acts on the clamping portions when the second member moves relative to the first member. This preliminary action ensures that the clamping force is immediately available and automatically applied without requiring manual intervention to activate the securing mechanism.

Inventive Principle:

Principle #10Preliminary action

4Extent of automation

If the first member and second member are configured to move toward or away from each other, then the bracket can autonomously clamp and retract, but the mechanism becomes more complex

Engineering Contradiction:

Improveautonomous clamping and retractionVSAvoidcomplexity of moving mechanism

Core Design Contradiction:

Extent of automationVSDevice complexity

Solution Approach 1:

The mechanism combines multiple functions into integrated components: the relative movement between first and second members simultaneously drives both the clamping portions to secure the device and the second member to retract into the first member. The spring assembly serves both to provide clamping force and to enable the retraction motion, reducing overall mechanical complexity.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

This disclosure provides a device fixing bracket and a vehicle, including a first member, a second member, a first clamping portion, a second clamping portion, and a pull-back structure. The first member and the second member are constructed to be capable of moving toward or moving away from each other along a target direction. When the device fixing bracket is in operation, the second clamping portion and the first clamping portion clamp a target device under a pull-back force. When the device fixing bracket is not in operation, at least a part of the second member is covered by the first member under the pull-back force. The device fixing bracket in this disclosure is small in size, and convenient and safe to use.
