Solution Overview

Problem

Existing pipe support systems are inadequate in absorbing movements and vibrations in all directions, leading to uneven stress distribution and increased risk of anchor failure, as they primarily focus on vertical movements and rely on spring forces that vary with elongation distance.

Innovation Solution

A pipe support device featuring a pressurized, impermeable elastic element between flanges, allowing for absorption of shifts in any direction, with a rigid structure under compression and adjustable pressure to maintain constant stress, using a fluid-filled elastic body of revolution attached to flanges via various fastening methods.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If spring-based supports are used to absorb vertical movements, then vertical vibration absorption is improved, but the ability to absorb movements in other directions deteriorates

Engineering Contradiction:
Improvevertical vibration absorptionVSAvoidmulti-directional movement absorption
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent uses an elastic membrane (thin film) that can deform in multiple directions to absorb pipe movements. The membrane replaces traditional spring mechanisms, providing flexibility in all directions rather than just vertical, while maintaining constant load through its elastic properties and pre-tensioning.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The patent replaces the mechanical spring system with a pneumatic system using an elastic membrane filled with pressurized gas. This substitution allows the support to maintain constant load independently of displacement, while the membrane's elasticity provides multi-directional movement absorption capability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Force

If spring force is used to support pipe load, then load absorption is improved, but stress distribution becomes uneven as elongation distance changes

Engineering Contradiction:
Improveload absorptionVSAvoidstress distribution uniformity
Core Design Contradiction:
ForceVSStability of the object's composition

Solution Approach 1:

The patent changes the fundamental parameter from spring force (which varies with elongation) to pneumatic pressure (which remains constant). The elastic membrane maintains constant internal pressure regardless of its deformation state, ensuring uniform stress distribution on the pipe throughout the movement range.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The elastic membrane automatically maintains constant load through its pre-tensioning and the compressibility of the enclosed gas. As the pipe moves, the membrane deforms but the gas pressure self-regulates to maintain constant supporting force, eliminating the need for external adjustment mechanisms.

Inventive Principle:
Principle #25Self-service

3Reliability

If elastic blocks are used to absorb vibrations, then vibration absorption is improved, but adaptability to different stress requirements deteriorates

Engineering Contradiction:
Improvevibration absorptionVSAvoidstress adaptation
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent uses a dynamic pneumatic system where the elastic membrane can adapt to varying stress conditions through pressure regulation. Unlike fixed elastic blocks, the pneumatic system allows dynamic adjustment of the supporting characteristics by changing the gas pressure, providing adaptability to different operational requirements.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The elastic membrane support device serves multiple functions: it absorbs vibrations, supports constant load, accommodates multi-directional movements, and adapts to different stress levels through pressure adjustment. This single device replaces multiple specialized components, providing universal applicability.

Inventive Principle:
Principle #6Universality (Multi-functionality)
