Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If adhesive member properties are measured using conventional test methods, then testing can be performed, but measurement accuracy is insufficient leading to product defects
Solution Approach 1:
The patent replaces conventional mechanical testing methods with a precision measurement system that uses a stage, temperature controlling portion, and jig portion with pressurization plate. This substitution enables accurate measurement of adhesive member properties including attachment force, separation force, and pressure distribution, thereby improving measurement accuracy and product reliability.
Solution Approach 2:
The patent implements precise control of temperature and pressure parameters during adhesive member testing. The temperature controlling portion maintains specific temperature conditions while the pressurization plate applies controlled pressure, allowing accurate measurement of adhesive properties under defined parameter conditions, which resolves the measurement accuracy issue.
2Measurement precision
If temperature and pressure are not precisely controlled during adhesive member testing, then testing process is simpler, but measurement accuracy and consistency deteriorate
Solution Approach 1:
The patent divides the testing apparatus into distinct functional segments: a stage for positioning, a temperature controlling portion for thermal management, and a jig portion with pressurization plate for pressure application. This segmentation allows each component to perform its specific function with high precision, improving measurement accuracy while maintaining manageable system complexity through modular design.
Solution Approach 2:
The patent introduces a jig portion as an intermediary component between the testing system and the adhesive member. The jig portion with its pressurization plate serves as a mediator that applies controlled pressure and enables accurate force measurement, bridging the gap between the testing apparatus and the adhesive member while ensuring precise measurement conditions.
3Productivity
If adhesive member properties are not accurately understood, then manufacturing process is faster, but product defects and malfunctions increase
Solution Approach 1:
The patent implements preliminary measurement and characterization of adhesive member properties before actual manufacturing. By using the stage, temperature controlling portion, and jig portion to pre-assess adhesive attachment force, separation force, and pressure distribution, the system ensures that only adhesive members meeting specified criteria proceed to manufacturing, thereby improving product reliability without significantly impacting production speed.

AI summary
An apparatus for manufacturing a display device, includes: a stage; a temperature controlling portion on the stage, and to receive a member seated on the temperature controlling portion; and a jig portion facing the temperature controlling portion, the jig portion to move linearly, and to receive an adhesive member. The jig portion includes: a first support plate; a second support plate facing the first support plate; and a pressurization plate on the first support plate and the second support plate, the pressurization plate to receive the adhesive member thereon. An end of the pressurization plate is spaced further from the member than an end of the first support plate and an end of the second support plate when the member is seated on the temperature controlling portion.
