Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If multiple molds are used for varying conveyor belt thicknesses, then manufacturing precision is improved, but device complexity and manufacturing costs increase

Engineering Contradiction:
Improvejoining device adaptation to belt thicknessVSAvoidnumber of molds required
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The joining device is designed with a universal structure that can accommodate multiple conveyor belt thicknesses using a single mold. The device includes adjustable components and a standardized interface that allows it to adapt to different belt specifications without requiring multiple specialized molds, thereby reducing manufacturing complexity while maintaining precision.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The joining device incorporates adjustable parameters such as modular spacers or variable thickness components that can be configured to match different conveyor belt thicknesses. This allows a single mold design to produce joining devices that can be adapted to various belt specifications by changing the configuration of these adjustable parameters rather than requiring multiple fixed molds.

Inventive Principle:
Principle #35Parameter changes

2Ease of manufacture

If traditional joining methods are used, then manufacturing costs increase, but there is no means for monitoring belt condition

Engineering Contradiction:
Improvemanufacturing costVSAvoidbelt condition monitoring capability
Core Design Contradiction:
Ease of manufactureVSLoss of information

Solution Approach 1:

The joining device merges the mechanical joining function with an integrated electronic monitoring system. Sensors and RFID chips are embedded within the joining device structure itself, combining the fastening mechanism and the monitoring capability into a single integrated component. This allows cost-effective manufacturing while simultaneously providing real-time belt condition monitoring that was previously unavailable with traditional joining methods.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The joining device performs self-monitoring of the conveyor belt condition through integrated sensors that continuously track parameters such as tension, temperature, and wear. This self-service monitoring capability is built into the joining device itself, eliminating the need for separate monitoring systems and reducing overall manufacturing costs while providing valuable belt condition information.

Inventive Principle:
Principle #25Self-service

3Reliability

If joining devices are made with high extensibility to withstand conveyor belt stresses, then reliability is improved, but device complexity increases

Engineering Contradiction:
Improveresistance to conveyor belt stressesVSAvoidstructural complexity of joining device
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The joining device utilizes composite materials that combine high extensibility with structural integrity. The device incorporates reinforced elastomer or synthetic material with embedded textile reinforcement, creating a composite structure that can withstand the tensile and compressive forces experienced during conveyor belt operation. This composite construction provides the necessary reliability without requiring overly complex structural designs.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The joining device is designed with dynamic characteristics that allow it to adapt to the varying stress conditions of conveyor belt operation. The material composition and structural design enable the device to exhibit appropriate extensibility under tension while maintaining stability under compression, allowing it to dynamically respond to operational loads without requiring complex mechanical adjustment mechanisms.

Inventive Principle:
Principle #15Dynamics
