Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If a complicated automatic inserting device is used to insert binding wire automatically, then the automation level and productivity are improved, but the device complexity and cost increase significantly

Engineering Contradiction:
Improveautomation of wire insertionVSAvoidstructure complexity
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The automatic inserting device is divided into independent functional modules: a wire holder that can be simply swung into position, a detector that triggers the insertion, and a swing mechanism. Each module performs a specific function, allowing the system to achieve automation without requiring a highly complex integrated structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The wire holder is designed to be swingable between a holding position and an inserting position, allowing it to dynamically adapt to the winding process. This dynamic positioning enables automatic insertion at the appropriate timing while maintaining structural simplicity through a single degree of freedom motion.

Inventive Principle:
Principle #15Dynamics

2Productivity

If a complicated automatic inserting device is used, then the productivity is improved, but the cost of the device increases

Engineering Contradiction:
Improveworking efficiencyVSAvoidmanufacturing cost
Core Design Contradiction:
ProductivityVSEase of manufacture

Solution Approach 1:

The detector automatically detects the intermediate winding point and triggers the wire holder to swing into the inserting position without requiring external control systems or complex sensors. The system uses the winding process itself to activate the insertion, eliminating the need for expensive control mechanisms while maintaining high productivity.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The invention uses simple, inexpensive components such as a basic swing mechanism and a straightforward detector instead of expensive automated positioning systems. These simple components are sufficient to achieve the required productivity without incurring high manufacturing costs.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Device complexity

If manual wire insertion is performed, then the device complexity is reduced, but the productivity and working efficiency deteriorate

Engineering Contradiction:
Improvestructure simplicityVSAvoidworking efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The wire holder swings automatically at the detected intermediate winding point, ensuring that wire insertion occurs continuously during the winding process without stopping or interrupting production. This maintains high productivity while keeping the device structure simple, as the insertion action is seamlessly integrated into the ongoing winding operation.

Inventive Principle:
Principle #20Continuity of useful action

4Ease of manufacture

If manual wire insertion is performed, then the manufacturing cost is reduced, but the working efficiency is poor

Engineering Contradiction:
Improvedevice costVSAvoidworking efficiency
Core Design Contradiction:
Ease of manufactureVSProductivity

Solution Approach 1:

The wire is pre-loaded into the wire holder in advance, and the holder is positioned ready for insertion before the winding process begins. When the detector identifies the intermediate winding point, the pre-positioned wire holder can immediately swing into place and perform insertion, achieving automatic operation with minimal complexity and high efficiency.

Inventive Principle:
Principle #10Preliminary action
