Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If motors are used to move the functional device along rails, then the apparatus can modify coating systems, but the apparatus becomes unstable due to its own weight and motor movement
Solution Approach 1:
The patent employs suction means (suction cups) to adhere the apparatus to the glazing panel, creating a counterbalancing force against the apparatus weight and motor movement forces. This adhesion mechanism stabilizes the apparatus during operation, allowing the motors to move the functional device along rails without compromising overall stability.
Solution Approach 2:
The apparatus divides the functional device into multiple independent units that can operate separately on different glazing panels. This segmentation allows each motorized unit to be smaller and lighter, reducing the stability issues caused by weight and motor movement while maintaining the overall capability to modify coating systems.
2Ease of operation
If the apparatus is mounted on suction pads, then it can be fixed on the glazing panel, but the precision of modification is insufficient due to instability
Solution Approach 1:
The suction means provide a stabilizing counterbalancing force that counteracts the apparatus weight and motor movement forces, creating a stable mounting platform. This stability ensures that the functional device can precisely modify coating interfaces while the apparatus remains firmly attached to the glazing panel.
Solution Approach 2:
The apparatus incorporates sensors that detect the position and status of the functional device during operation. This feedback mechanism allows real-time adjustments to maintain precision during coating modification, compensating for any minor instabilities caused by motor movement or apparatus weight.
3Productivity
If the laser is moved along rails to scribe the coating system, then electromagnetic transmission is improved, but dynamic shocks reduce precision
Solution Approach 1:
The motors move the laser along rails in a controlled periodic manner, with acceleration and deceleration phases designed to minimize dynamic shocks. This periodic motion pattern allows the laser to efficiently scribe the coating system while maintaining precision by reducing impact forces during start and stop cycles.
Solution Approach 2:
The apparatus incorporates damping elements and shock-absorbing mechanisms in the rail system that cushion the laser movement before dynamic shocks occur. This prior cushioning reduces the impact of acceleration and deceleration forces, maintaining scribe precision while allowing efficient coating modification.
