Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual operator checking is used to monitor glue heating, then the operator can detect glue state, but time is wasted and glue may cure due to inattention

Engineering Contradiction:
Improveglue heating monitoring reliabilityVSAvoidoperator checking time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system uses temperature detection means and a control system to automatically monitor and control the heating process, allowing the system to serve itself without operator intervention. The logic control unit continuously monitors temperature and activates/deactivates heating actuators based on detected temperature values, eliminating the need for manual checking.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system implements a feedback loop where temperature detection means continuously measure the internal temperature of the gluing device, and the logic control unit uses this feedback information to automatically control the heating actuators. This closed-loop control ensures the glue reaches the correct temperature without operator intervention.

Inventive Principle:
Principle #23Feedback

2Productivity

If multiple gluing devices are heated manually, then all devices can be processed, but the operator's time increases significantly

Engineering Contradiction:
Improvenumber of gluing devices processedVSAvoidtotal checking time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The control system is designed to universally control multiple gluing devices simultaneously. The logic control unit can manage several heating actuators and temperature detection means across multiple devices, allowing one operator to supervise multiple devices at once without proportionally increasing checking time.

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

Solution Approach 2:

Each gluing device is equipped with its own temperature detection means and heating actuators controlled by the logic control unit, allowing the devices to self-regulate their heating processes. This eliminates the need for operators to individually monitor each device, enabling efficient processing of multiple devices simultaneously.

Inventive Principle:
Principle #25Self-service

3Extent of automation

If automated temperature control is implemented, then heating process is automated, but device complexity increases

Engineering Contradiction:
Improveheating process automationVSAvoidcontrol system complexity
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The system replaces manual mechanical checking with automated electronic temperature detection means and electronic control. The logic control unit uses electronic signals to monitor temperature and control heating actuators, substituting mechanical operator intervention with electronic automation while keeping the overall structure relatively simple.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
