Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the substrate is attached to a carrier for movement during manufacturing, then the substrate can be transported and processed, but excessive force can be applied to the substrate causing damage and defects
Solution Approach 1:
The patent introduces a carrier as an intermediary object between the substrate and the handling system. The carrier includes a support structure with a first surface for mounting the substrate and a second surface that contacts the handling mechanism. This intermediary carrier absorbs and distributes forces during attachment and transport, preventing direct transmission of excessive force to the substrate and thus resolving the contradiction between enabling transport and preventing damage.
Solution Approach 2:
The support structure of the carrier is designed with specific mechanical properties to provide beforehand cushioning. The support includes a first surface for substrate mounting and a second surface for contact, creating a cushioning layer that absorbs shock and excessive force during the attachment process. This prior cushioning mechanism ensures that even if excessive force is applied during handling, the substrate is protected from damage.
2Productivity
If the substrate is not in a perfectly flat position during attachment, then attachment speed can be maintained, but excessive force is applied causing substrate damage
Solution Approach 1:
The carrier support structure is designed with dynamic characteristics that allow it to adapt to substrate position variations. The support can flex and adjust during the attachment process, maintaining contact without applying excessive force even when the substrate is not perfectly flat. This dynamic adaptation enables continuous operation at high speed while preventing damage from position misalignment.
Solution Approach 2:
The patent employs parameter changes in the mechanical properties of the carrier support. The support structure has controlled flexibility and compliance parameters that allow it to accommodate position variations of the substrate. By adjusting these mechanical parameters, the system can maintain high attachment speed while the support absorbs position errors without transmitting damaging forces to the substrate.
3Stability of the object's composition
If a rigid support structure is used for substrate mounting, then structural stability is improved, but excessive force is transmitted to the substrate causing damage
Solution Approach 1:
The carrier support structure exhibits local quality differentiation. Different regions of the support have different mechanical properties: the first surface that contacts the substrate has compliant, force-distributing characteristics, while other portions maintain structural rigidity for stability. This local differentiation allows the support to provide stability where needed while preventing force transmission to the substrate at critical contact points.
Solution Approach 2:
The support structure employs composite construction with materials or structures that combine rigidity and compliance. The carrier includes a support with a first surface for substrate mounting and a second surface for contact, creating a composite structure that provides both structural stability and force absorption. This composite design enables the support to maintain stability during transport while cushioning forces during attachment operations.
