Solution Overview

Problem

Existing high-altitude installation equipment for building materials relies on unified vacuum pumps that can fail if damaged, leading to safety hazards and high maintenance costs due to the need for complete replacement, and is prone to malfunction and damage from rainwater.

Innovation Solution

An integrated vacuum suction pad system with independent pads that can adsorb and release building materials independently, featuring a vacuum tank that maintains negative pressure without the vacuum pump, reducing reliance on it and allowing individual pad maintenance, along with a protective design to prevent rainwater ingress.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If unified vacuum pump controls all pads, then adsorption control is simplified, but safety decreases and maintenance cost increases when pump fails

Engineering Contradiction:
Improveadsorption control complexityVSAvoidadsorption equipment reliability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The vacuum system is segmented into independent pad units, each with its own vacuum pump and control valve. This allows individual pads to be controlled separately, improving reliability since one pad failure does not affect others, while maintaining manageable complexity through modular design

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Each pad can independently adjust its vacuum level through individual control valves, allowing parameter optimization for different building materials and conditions, while maintaining system simplicity through standardized modular units

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If reverse inflation is used to separate pad from building material, then adsorption release is achieved, but time consumption increases and control sensitivity decreases

Engineering Contradiction:
Improveadsorption release operationVSAvoidstate switching time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The release mechanism extracts the complex reverse inflation process and replaces it with a simple valve opening action. The control valve directly opens to atmospheric pressure, eliminating the need for reverse inflation cycles and significantly reducing state switching time

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The mechanical reverse inflation system is replaced with a direct atmospheric pressure release through the control valve, simplifying the operation and improving response time by eliminating intermediate mechanical steps

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

3Stability of the object's composition

If vacuum pump runs continuously to maintain negative pressure, then adsorption stability is maintained, but vacuum pump service life decreases and malfunction probability increases

Engineering Contradiction:
Improvenegative pressure stabilityVSAvoidvacuum pump service life
Core Design Contradiction:
Stability of the object's compositionVSDuration of action of stationary object

Solution Approach 1:

The vacuum pump operates periodically rather than continuously, maintaining negative pressure in the common chamber through intermittent pumping cycles. This reduces wear and extends service life while maintaining adequate adsorption stability through the pressure retention capability of the chamber

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The common chamber acts as a pressure buffer, cushioning against pressure fluctuations and maintaining stable negative pressure even when the vacuum pump is not running, thereby reducing pump operation time and extending service life

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

4Device complexity

If vacuum pump is installed close to adsorption part, then connection is simplified, but rainwater damage risk increases and vibration transmission occurs

Engineering Contradiction:
Improveconnection structure complexityVSAvoidrainwater damage and vibration
Core Design Contradiction:
Device complexityVSObject-affected harmful factors

Solution Approach 1:

The system is segmented into independent pad modules with integrated vacuum pumps, allowing each unit to be positioned optimally. The mounting plate provides a standardized interface that simplifies connections while enabling spatial separation to avoid rainwater and vibration issues

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The mounting plate serves as an intermediary component between the adsorption part and vacuum pump, providing a standardized connection interface that simplifies assembly while allowing spatial separation to protect the vacuum pump from rainwater and vibration

Inventive Principle:
Principle #24Intermediary (Mediator)
