Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the electronic device is positioned between two rubber strips using conventional methods, then the encapsulation is achieved, but the positioning precision is poor and damage occurs during cutting
Solution Approach 1:
The patent applies preliminary action by pre-positioning the electronic device between the two rubber strips before the cutting operation. The strips are prepared and the device is placed in its final position while the material is still in a manageable state, ensuring precise positioning before any cutting occurs. This prevents damage during cutting because the device is already secured in place.
Solution Approach 2:
The patent utilizes parameter changes by controlling the temperature of the rubber strips during the encapsulation process. The strips are heated to a specific temperature range that allows for precise positioning and secure bonding of the electronic device without causing damage. This temperature control enables high precision positioning while maintaining device integrity.
2Productivity
If conventional encapsulation processes are used, then electronic device encapsulation is achieved, but continuous manufacturing cannot be performed
Solution Approach 1:
The patent implements continuity of useful action by designing a process where rubber strips are continuously fed and processed through the encapsulation system. The electronic devices are continuously positioned and sealed between the strips without interruption, enabling continuous manufacturing. This eliminates the need for batch processing and improves industrial operability while maintaining ease of manufacture through automated continuous operation.
3Reliability
If the electronic device is encapsulated in rubber strips, then protection during storage is improved, but positioning precision and cutting integrity are compromised
Solution Approach 1:
The patent applies parameter changes by controlling the temperature and physical state of the rubber strips during the encapsulation process. The strips are heated to a specific temperature range that allows for precise positioning and secure bonding of the electronic device without causing damage. This temperature control enables high precision positioning while maintaining device integrity.
Solution Approach 2:
The patent applies preliminary action by pre-positioning the electronic device between the two rubber strips before the cutting operation. The strips are prepared and the device is placed in its final position while the material is still in a manageable state, ensuring precise positioning before any cutting occurs.
