Solution Overview

Problem

Current hot stamping machines for license plates have low working efficiency due to the need for manual involvement in feeding and discharging and require prolonged heating times, as the license plate cools the upper heating plate when contacted.

Innovation Solution

Incorporating a lower heating plate to preheat the license plate before hot stamping, which maintains the upper heating plate's temperature, and using a gravity sensor and automated mechanisms for feeding and discharging, eliminating manual intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual feeding and discharging is used, then device complexity is reduced, but productivity decreases and labor efficiency is low

Engineering Contradiction:
Improvehot stamping efficiencyVSAvoidautomation mechanism complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system performs self-service through automated mechanisms: the lifting mechanism automatically feeds license plates onto the processing platform, the grabbing device automatically discharges stamped plates, and the lower heating plate automatically preheats plates. This eliminates manual intervention while maintaining manageable device complexity through standardized automated components.

Inventive Principle:
Principle #25Self-service

2Duration of action of moving object

If only upper heating plate is used, then device complexity is reduced, but heating time increases and energy efficiency decreases

Engineering Contradiction:
Improveheating timeVSAvoidheating system complexity
Core Design Contradiction:
Duration of action of moving objectVSDevice complexity

Solution Approach 1:

The lower heating plate performs preliminary heating action on the license plate before it contacts the upper heating plate. This preheating reduces the thermal mass that the upper heating plate must heat, significantly shortening the overall heating time and improving energy efficiency while using a manageable dual-plate heating system.

Inventive Principle:
Principle #10Preliminary action
