Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cover is added to protect the driving integrated circuit chip from static electricity, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent applies this principle by using a flexible cover made of conductive material that can be bent to conform to the contours of the display panel and circuit board. The cover includes a body portion covering the driving integrated circuit chip and a bent portion surrounding the edge of the display panel, allowing it to flexibly adapt to the device geometry while maintaining electrostatic discharge protection without adding rigid structural complexity
Solution Approach 2:
The cover serves multiple functions simultaneously: it provides electrostatic discharge protection to the driving integrated circuit chip, acts as a grounding path through its conductive material, and conforms to the device geometry by bending around edges. This multi-functionality reduces the need for separate protective components, thereby limiting the increase in device complexity
2Reliability
If the cover is designed to fully surround the display panel edge, then protection coverage is improved, but the device size increases
Solution Approach 1:
The patent applies this principle by transitioning the cover from a two-dimensional flat structure to a three-dimensional bent structure that follows the edge contours of the display panel. The bent portion extends downward from the front surface to surround the edge, providing comprehensive protection coverage while containing the additional material within the device's vertical profile rather than expanding the horizontal footprint
3Reliability
If the cover material is made thick for better shielding, then protection effectiveness is improved, but weight increases
Solution Approach 1:
The patent applies this principle by using conductive material with specific electrical conductivity properties rather than relying solely on material thickness for shielding effectiveness. The conductive material provides electrostatic discharge protection through its electrical properties, allowing for thin-weight construction while maintaining protection effectiveness. The material may be a composite or treated material that combines structural integrity with electrostatic shielding capabilities
