Problem

Conveyor belts used in industries often accumulate foreign substances, leading to contamination and inefficiencies in cleaning processes, particularly in maintaining hygiene and productivity.

Innovation Solution

A steam conveyor belt cleaning apparatus that includes a steam chamber unit, suction chamber unit, foreign substance brush unit, partition wall, steam injection port, foreign substance discharge unit, and air suction ports, which uses high-temperature steam to detach and discharge foreign substances, ensuring a hygienic and stable conveyor belt surface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional scrapers are used to remove foreign substances from conveyor belt, then some foreign substances can be removed, but foreign substances are not perfectly discharged and remain on the conveyor belt surface

Engineering Contradiction:
Improvecleaning effectivenessVSAvoidforeign substance discharge completeness
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The cleaning apparatus is divided into multiple functional modules: steam injection unit, brush unit, suction unit, and discharge unit. Each module performs a specific function in the cleaning process, working sequentially to achieve complete foreign substance removal. The segmentation allows optimized performance of each function while maintaining overall system effectiveness.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Steam is introduced as an intermediary substance to facilitate the removal of foreign substances. The steam softens and loosens adhered contaminants, making them easier for the brush to detach and for the suction unit to remove. This intermediary approach enhances the overall cleaning effectiveness without requiring excessive mechanical force.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If manual cleaning intervention is used, then foreign substances can be removed, but work efficiency decreases and hygiene standards cannot be consistently maintained

Engineering Contradiction:
Improvehygiene standard consistencyVSAvoidwork efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The cleaning apparatus is designed to operate autonomously on the moving conveyor belt without requiring manual intervention. The system self-regulates the steam injection, brush rotation, suction, and discharge processes, maintaining consistent hygiene standards while improving work efficiency. The automated operation ensures uniform cleaning quality across the entire conveyor belt surface.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The cleaning apparatus operates continuously as the conveyor belt moves through it, providing uninterrupted cleaning action. The steam injection, brushing, suction, and discharge processes occur in continuous sequence, ensuring that the entire conveyor belt surface is treated without gaps. This continuous operation maintains consistent hygiene standards while maximizing productivity.

Inventive Principle:
Principle #20Continuity of useful action

3Productivity

If steam is used to detach foreign substances, then cleaning effectiveness improves, but additional system complexity is introduced

Engineering Contradiction:
Improveforeign substance detachment efficiencyVSAvoidsystem structure complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The steam injection unit is integrated with the brush unit, suction unit, and discharge unit into a single compact cleaning apparatus. This merging of functions into one unified system achieves effective foreign substance detachment while minimizing the overall structural complexity. The compact design allows all components to work in close proximity, facilitating efficient space utilization and simplified installation.

Inventive Principle:
Principle #5Merging (Combining)
