Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual work is used to paste buffer rubber strips, then flexibility in assembly is maintained, but assembling accuracy is low and product yield is reduced
Solution Approach 1:
The patent replaces the manual mechanical pasting operation with an automated liquid adhesive filling system. The liquid adhesive is dispensed through a nozzle to automatically apply adhesive to the buffer rubber strip, eliminating manual labor while achieving high positioning accuracy and consistent adhesive application.
Solution Approach 2:
The patent changes the state of adhesive from pre-formed double-sided tape to liquid adhesive that can be precisely controlled during dispensing. This allows for adjustable adhesive quantity, position, and distribution parameters to be optimized for maximum assembly accuracy and efficiency.
2Strength
If double sided adhesive tape is added to buffer rubber strip, then bonding strength is improved, but device complexity and production cost increase
Solution Approach 1:
The patent combines the adhesive application step with the buffer rubber strip placement operation. The liquid adhesive is applied directly to the buffer rubber strip or the component surface in the same automated operation, eliminating the need for separate double-sided tape application and reducing overall process complexity.
Solution Approach 2:
The patent extracts the adhesive function from the double-sided tape component and implements it as a separate liquid adhesive application process. This allows for better control over adhesive placement and eliminates the need to handle and position pre-cut adhesive tapes, simplifying the overall assembly process.
3Productivity
If buffer rubber strip is pasted manually, then equipment investment is reduced, but productivity is low and production efficiency is reduced
Solution Approach 1:
The patent replaces manual pasting operations with automated liquid adhesive dispensing equipment. The automated system can rapidly apply adhesive with consistent quality, significantly increasing production speed and efficiency while reducing labor requirements and associated costs.
4Manufacturing precision
If groove for fixing buffer strip is added to rubber frame, then position accuracy is improved, but manufacturing complexity increases
Solution Approach 1:
The patent incorporates the positioning groove design into the rubber frame manufacturing process itself. The grooves are molded or formed during the initial rubber frame production, serving as built-in positioning features that guide the buffer rubber strip placement without requiring additional assembly steps or complex fixtures.

AI summary
The present invention discloses an LCD module manufacturing method and an LCD module. The LCD module manufacturing method comprises: arranging a groove for fixing the buffer strip in the surface position of the rubber frame of the LCD module for supporting the LCD panel. In the present invention, because the corresponding position of the rubber frame for supporting the LCD panel is provided with a groove, a region for limiting the position of the buffer rubber strip is formed by using the groove, the arranging position accuracy of the buffer rubber strip is increased, and the product quality is increased.
