Interleaving Element for Ultra-Thin Glass Roll Adhesion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During the roll-to-roll process of ultra-thin flexible glass substrates, radial inner sections adhere to adjacent outer sections, leading to breakage of the glass substrates and potential damage to electronic components disposed on them.
Innovation Solution
An interleaving element comprising elongated side elements and bridging elements is used to separate the glass substrate sections, where the bridging elements correspond to spacing zones and the side elements correspond to edge zones, creating a hollowed section that houses the active area, preventing adhesion between inner and outer sections.

Engineering Contradiction Analysis
1Productivity
If roll-to-roll process is used to manufacture ultra-thin flexible glass substrates, then manufacturing efficiency is improved, but adhesion between inner and outer sections occurs causing breakage
Solution Approach 1:
An interleaving element is introduced as an intermediary component between adjacent glass substrate sections during the roll-to-roll process. This element physically separates the inner and outer sections, preventing direct contact and adhesion while allowing the substrates to be rolled together efficiently. The interleaving element acts as a mediator that enables the manufacturing process to proceed without causing substrate breakage.
2Speed
If glass substrate sections are rolled together in roll-to-roll process, then production speed is improved, but electronic components on substrate are easily broken or damaged
Solution Approach 1:
The interleaving element serves as a protective intermediary that prevents direct contact between glass substrate sections during high-speed rolling. By physically separating adjacent sections, it protects electronic components on the substrate surfaces from mechanical damage, stress concentration, and adhesion forces that would otherwise occur during the rolling process.
Solution Approach 2:
The interleaving element divides and segments adjacent glass substrate sections during the rolling process. By creating physical separation between sections, it prevents the harmful effects of rolling contact on electronic components while maintaining the efficiency of continuous production.
