Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If chip units and substrate units are connected using flexible connecting devices with anisotropic conductive film bonding or metal-welding, then electrical connection and signal transmission are achieved, but the flexible connecting devices are damaged during separation leading to high waste rates
Solution Approach 1:
The patent divides the connection system into separate components: a rigid connection unit with conductive patterns and flexible connection units that can be independently separated. The rigid connection unit remains on the substrate while flexible connection units can be detached without damage, enabling recycling and reducing waste.
Solution Approach 2:
The patent introduces a rigid connection unit as an intermediary between the substrate and flexible connection units. This rigid unit with conductive patterns serves as a stable interface that allows flexible units to be connected and disconnected without damaging the flexible materials themselves.
2Productivity
If sequential signal transmission is implemented through multiple connection units, then signal transmission efficiency is improved, but device complexity increases
Solution Approach 1:
The signal transmission path is segmented into multiple independent connection units (first flexible connection unit, rigid connection unit, second flexible connection unit) that can be separately manufactured and assembled. Each unit has a specific function, allowing modular design that simplifies overall system complexity while enabling sequential signal transmission.
Solution Approach 2:
The rigid connection unit with its conductive patterns serves multiple functions: it provides electrical connection, structural support, and a standardized interface for connecting flexible units. This multi-functionality reduces the need for separate components, thereby managing complexity while maintaining transmission efficiency.
