Solution Overview

Problem

In bamboo machining, the manual sorting of bamboo outer and inner layers after splitting is inefficient and hazardous due to the need for multiple operators to feed bamboo splits into a planer, with fiber burrs and untidy node diaphragms posing injury risks.

Innovation Solution

A node diaphragm scraping and sorting device comprising a scraping device, a sorting device, and a clamping and conveying device, which arranges bamboo splits so that outer and inner layers face the same direction, using conical cylinders, pressing semi-rings, shifting forks, and elastic sheets to automate the sorting process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual sorting of bamboo outer and inner layers is performed after splitting, then the bamboo splits can be fed into the planer, but the number of operators increases and injury risk increases due to fiber burrs and untidy node diaphragms

Engineering Contradiction:
Improvemanual sorting operationVSAvoidinjury risk from fiber burrs and node diaphragms
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The device enables the bamboo splits to self-sort and self-align through the scraping action and mechanical arrangement. The scraping ring removes node diaphragms that would otherwise cause injury, while the conical cylinder and pressing semi-rings automatically position the bamboo outer and inner layers facing the same direction, eliminating the need for manual sorting operators.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The scraping ring extracts and removes the harmful node diaphragms from the bamboo splits. By taking out these untidy node diaphragms before the bamboo enters the planer, the device eliminates the injury risk to operators while maintaining the sorting function.

Inventive Principle:
Principle #2Taking out (Extraction)

2Productivity

If multiple operators are used to feed bamboo splits into the planer, then the sorting can be performed, but the labor cost and operational complexity increase

Engineering Contradiction:
Improvesorting efficiencyVSAvoidnumber of operators required
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The bamboo splits perform their own sorting and alignment through the mechanical action of the scraping device and conical cylinder arrangement. The device structure itself provides the sorting function that previously required multiple human operators, thereby increasing productivity while reducing operational complexity.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The device segments the sorting function into distinct mechanical components: the conical cylinder for positioning, the scraping ring for removing node diaphragms, and the pressing semi-rings for alignment. This segmentation allows each component to perform a specific sorting task automatically, replacing multiple operators with a coordinated mechanical system.

Inventive Principle:
Principle #1Segmentation

3Productivity

If node diaphragms are not scraped, then the bamboo splits can be processed, but the fiber burrs and untidy node diaphragms stab operators increasing injury risk

Engineering Contradiction:
Improvecontinuous processing capabilityVSAvoidinjury risk from fiber burrs and node diaphragms
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The scraping ring performs preliminary action by removing node diaphragms and fiber burrs before the bamboo splits enter the planer. This preliminary cleaning action eliminates the harmful factors that would otherwise stab operators during subsequent handling and processing operations.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The scraping ring extracts and removes the harmful node diaphragms and fiber burrs from the bamboo splits. By taking out these harmful elements in advance, the device enables continuous processing capability while eliminating the injury risk to operators during handling.

Inventive Principle:
Principle #2Taking out (Extraction)

4Ease of operation

If bamboo outer layers and inner layers are not arranged in sequence, then the planer can process the bamboo splits, but the machining efficiency decreases due to repeated manual arrangement

Engineering Contradiction:
Improveplaner operationVSAvoidmachining efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The bamboo splits automatically arrange themselves in the correct sequence with outer and inner layers facing the same direction through the conical cylinder and scraping ring mechanism. This self-arrangement eliminates the need for repeated manual arrangement operations, thereby improving machining efficiency while maintaining ease of planer operation.

Inventive Principle:
Principle #25Self-service
