Solution Overview

Problem

Conventional pipe binding devices fail to prevent water leakage during high-pressure unclogging and are not easily integrated with pipes, leading to separation and inefficiencies in repair and exchange processes.

Innovation Solution

A pipe binding device featuring a ring-shaped band with pressurizing pins that apply forces to move pipes closer together, integrated with a tightening plate and adjustable bands to ensure secure connection and prevent water leakage, allowing for easy repair and exchange without bonding.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If conventional pipe binding devices are used to connect pipes, then the connection can be made without bonding, but the pipes are pushed and separated during high-pressure unclogging causing water leakage

Engineering Contradiction:

Improveconnection without bondingVSAvoidprevention of pipe separation during high-pressure unclogging

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The pressurizing pins are inserted into the pipes, with the pin bodies extending into the pipe interiors and the heads positioned outside. This nesting configuration allows the binding device to be integrated with the pipes, enabling the pins to effectively transmit pressing forces from the band body to the pipes during high-pressure unclogging operations.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The pressurizing pins are pre-installed on the band body before the binding operation. When the band body is tightened around the pipes, the pins are already positioned to receive and transmit the pressing forces, ensuring immediate effectiveness in preventing pipe separation during subsequent high-pressure unclogging.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If the band body is tightened to apply close contact coupling forces to the pipes, then water leakage is prevented, but the pipes may be pushed apart by high-pressure water flow

3Reliability

If pressurizing forces are applied to move pipes closer together, then connection reliability is improved, but the device complexity increases

Engineering Contradiction:

Improveconnection reliabilityVSAvoidstructure with pressurizing pins

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

Instead of uniformly increasing the complexity of the entire binding device, the pressurizing pins are strategically positioned at specific locations on the band body. Each pin is placed to target specific areas where additional pressing force is needed to move the pipes closer together, providing localized enhancement without overall system complexity increase.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The band body is made of a flexible material that can elastically deform when tightened. This flexibility allows the band body to naturally conform to the pipes and distribute the pressing forces, reducing the need for complex rigid structural components while still achieving reliable pipe connection.

Inventive Principle:

Principle #30Flexible shells and thin films

AI summary

A pipe binding band comprises: a band body which is formed in a ring shape so as to surround interconnection end portions of a first and a second pipe in the circumferential direction and has a structure capable of adjusting a close contact coupling force to the external surfaces of the first and the second pipe through an adjustment member; and a plurality of pressing pins which are arranged to be spaced apart from each other along the longitudinal direction of the band body and provide a pressing force to the first and the second pipe so that the first and the second pipe move in a direction closer to each other as the close contact coupling force increases.
