Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If thermal interface pads are placed close together on a delivery roll for efficient space utilization, then the quantity of pads per roll increases, but the pads may melt together in warm conditions rendering the roll unusable
Solution Approach 1:
The delivery roll is divided into individual pad compartments separated by spacer members. Each pad is isolated in its own segment, preventing contact with adjacent pads even when the material becomes soft from heat exposure during transport or storage.
Solution Approach 2:
Spacer members are introduced as intermediary elements between adjacent thermal interface pads. These spacers act as physical barriers that maintain separation between pads, preventing them from melting together while allowing the pads to be stored in close proximity for efficient space utilization.
2Reliability
If thermal interface pads are covered with liners during transport, then the pads are protected from contamination and damage, but the application process becomes more complex requiring additional removal steps
Solution Approach 1:
The bottom liner is selectively removed or left attached depending on the application needs. The design allows the bottom liner to be taken off during application if desired, while the top liner remains as a protective covering that can be peeled back to expose the adhesive surface.
Solution Approach 2:
The pads are pre-prepared with liners attached during manufacturing, providing immediate protection during transport and storage. The liner configuration is designed to allow easy removal or peeling during application, balancing protection with ease of use.
3Reliability
If the adhesive layer is made highly adhesive to securely hold pads on the carrier tape, then the pads remain stable during transport, but the pads become difficult to remove from the tape during application
Solution Approach 1:
The adhesive layer is applied in specific locations and with specific properties to achieve different performance characteristics in different areas. The adhesive is strong enough to hold pads securely during transport but can be selectively overcome during application by pulling on the liner or using a picking tool.
Solution Approach 2:
The adhesive is pre-applied to the carrier tape in controlled patterns before pads are attached. This allows optimization of adhesive strength and distribution to balance secure holding during transport with ease of removal during application.
