Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If the pipe channel is fixedly connected to the H-beam using a bracket, then the structural stability is improved, but the vibration generated in the pipe is transferred to the H-beam and grating

Engineering Contradiction:

Improvestructural stabilityVSAvoidvibration transfer

Core Design Contradiction:

Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a vibration-proof bracket as an intermediary element between the pipe channel and the H-beam. This bracket includes a vibration-proof unit that acts as a mediator to block the transmission path of vibration from the pipe to the structural steel member, while still maintaining the structural connection and stability.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The invention extracts the vibration transmission function from the bracket by separating the fixing function from the vibration transmission function. The bracket is designed to fix the pipe channel to the H-beam while simultaneously preventing vibration transmission through the use of vibration-proof units that isolate the two components.

Inventive Principle:

Principle #2Taking out (Extraction)

2Strength

If rigid connection is used between the bracket and structural steel member, then the fixing strength is improved, but the vibration is efficiently transmitted to the outside

Engineering Contradiction:

Improvefixing strengthVSAvoidvibration transmission

Core Design Contradiction:

StrengthVSObject-generated harmful factors

Solution Approach 1:

The vibration-proof bracket employs composite construction by combining rigid components (for maintaining fixing strength) with elastic or damping materials (for blocking vibration transmission). This composite approach allows the bracket to simultaneously achieve strong fixation and effective vibration isolation.

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The invention changes the physical parameters of the bracket by incorporating elements with different rigidity and damping characteristics. The bracket structure is designed to have high rigidity for fixing strength while incorporating compliant or damping elements that change the vibration transmission parameters to block harmful vibrations.

Inventive Principle:

Principle #35Parameter changes

3Stability of the object's composition

If the pipe is fixedly disposed on the horizontal channel, then the positioning stability is improved, but the vibration from the pipe is transferred to the channel and H-beam

Engineering Contradiction:

Improvepositioning stabilityVSAvoidvibration transfer to channel

Core Design Contradiction:

Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The vibration-proof bracket serves as an intermediary between the pipe channel and the H-beam, preventing vibration transmission while maintaining the fixed positioning of the pipe on the horizontal channel. The bracket isolates the vibration path without compromising the structural connection.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The invention segments the connection system into distinct functional components: the bracket for positioning and support, and the vibration-proof unit for isolation. This segmentation allows the pipe to be stably positioned on the horizontal channel while the vibration-proof bracket prevents vibration transmission to the H-beam.

Inventive Principle:

Principle #1Segmentation

AI summary

Disclosed is a pipe vibration-proof channel capable of preventing vibration generated in a pipe from being transferred to the outside. Here, since a vertical channel connected to a horizontal channel on which the pipe is disposed is disposed to be separated from a structural section steel member, it is possible to prevent the vibration generated in the pipe from being transferred to the structural section steel member. Also, since a vibration-proof unit capable of absorbing the vibration of the pipe is disposed on a pipe fixing portion configured to fix a vibration-proof bracket and the pipe, it is possible to prevent the vibration of the pipe from being transferred to the vertical channel.
