Solution Overview

Problem

The existing methods for securing vibration-generating components in electronic devices require additional parts like dedicated screws, increasing assembly time and occupying valuable space, especially in slim and lightweight designs where internal space is limited.

Innovation Solution

A vibration-proof fixing structure that includes a housing with a vibration-generating component, a vibration-proof member with an insertion hole, and a fixing protrusion with an extended shoulder, which is inserted into the vibration-proof member to dampen vibrations without the need for additional screws, allowing for a compact design.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a dedicated screw is used to secure the vibration-generating component, then the component is firmly fixed and vibration is dampened, but the assembly time increases and additional space is occupied

Engineering Contradiction:

Improvefixing reliabilityVSAvoidassembly time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent combines the fixing function and vibration damping function into a single integrated vibration-proof member. The elastic material of this member provides both mechanical fastening (replacing the screw) and vibration isolation, thereby reducing assembly steps and time while maintaining fixing reliability.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The vibration-proof member serves multiple functions simultaneously: it acts as a fastening element (replacing the dedicated screw), provides vibration isolation, and ensures reliable mounting. This multi-functionality eliminates the need for separate components, reducing assembly complexity and time.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If a dedicated screw is used to secure the vibration-generating component, then the component is firmly fixed, but the space occupation within the device increases

Engineering Contradiction:

Improvefixing reliabilityVSAvoidspace occupation

Core Design Contradiction:

ReliabilityVSVolume of moving object

Solution Approach 1:

The patent merges the fastening component and vibration isolation component into a single integrated vibration-proof member. This eliminates the need for a dedicated screw and separate dampers, significantly reducing the total volume occupied by fastening and isolation mechanisms within the device.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The vibration-proof member performs multiple functions (fastening and vibration isolation) in a single component, reducing the overall space requirement compared to using separate dedicated screws and vibration dampers.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If multiple separate components are used for mounting, then the vibration-generating component is securely fixed, but the device complexity and assembly difficulty increase

Engineering Contradiction:

Improvemounting securityVSAvoidassembly complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent integrates multiple functions (fastening, vibration isolation, and positioning) into a single vibration-proof member with specific structural features (engaging groove, insertion hole, extended shoulder). This integration simplifies the overall mounting structure and reduces assembly complexity while maintaining secure fixation.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The vibration-proof member is designed with segmented functional zones: an engaging groove for securing the vibration-generating component, an insertion hole for the fixing protrusion, and an extended shoulder for positioning. This segmentation of functions within a single component maintains mounting security while simplifying the overall structure.

Inventive Principle:
