Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual assembly method is used, then assembly flexibility is maintained, but production efficiency is low

Engineering Contradiction:

Improveproduction efficiencyVSAvoidautomation level

Core Design Contradiction:

ProductivityVSExtent of automation

Solution Approach 1:

The assembly system is divided into multiple independent modules: rod dispensing device, head dispensing device, conveying flap, clamping device, and assembling device. Each module performs a specific function and can operate independently, enabling automated assembly while maintaining system flexibility through modular architecture.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A conveying flap acts as an intermediary between the rod dispensing device and the assembling device. It automatically transfers rod bodies through swinging motion between different positions, eliminating the need for manual handling while coordinating the operation of different automated modules.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If automated assembly system is implemented, then production efficiency is improved, but device complexity increases

Engineering Contradiction:

Improveassembly speedVSAvoidsystem complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The conveying flap serves multiple functions: it conveys rod bodies from the dispensing device to the clamping device, positions components during assembly, and transfers finished products to the output channel. This multi-functionality reduces the need for separate dedicated mechanisms for each operation.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system uses gravity as a natural force to dispense rod bodies and pulling heads from their respective storage devices. By designing inclined guiding plates and downward-open falling channels, components automatically move to positioning locations without requiring additional actuators or energy input.

Inventive Principle:

Principle #12Equipotentiality

3Use of energy by moving object

If gravity-based dispensing is used, then energy consumption is reduced, but positioning precision may be affected

Engineering Contradiction:

Improveenergy consumptionVSAvoidpositioning accuracy

Core Design Contradiction:

Use of energy by moving objectVSMeasurement precision

Solution Approach 1:

The system replaces complex mechanical positioning mechanisms with gravity-based dispensing combined with simple guiding structures. Inclined guiding plates and falling channels guide components along predetermined paths, achieving accurate positioning through geometric constraints rather than active mechanical control.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

Rod bodies and pulling heads automatically position themselves through gravity-driven movement along guiding plates and falling channels. The components' own weight serves as the driving force, eliminating the need for external actuators while achieving consistent positioning through the designed gravitational path.

Inventive Principle:

Principle #25Self-service

AI summary

A method for assembling a dual-head pulling rod involves attaching pulling heads to two ends of a rod body through threaded connection using a system that includes a foundation, on which a rod dispensing device, an inclined guiding plate, a conveying flap, a head dispensing device, a head mounting unit, a clamping device, an assembling device and a V-shaped output channel are provided. The inclined guiding plate is inclined and uses its ramp to guide a rod body falling thereon. The conveying flap is swingable between an input position and an output position. The conveying flap at the input position receives the rod body coining from the inclined guiding plate and outputs the rod body to the clamping device.
