Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cutting tools face contamination and reduced cutting ability due to adhesive substance attachment during the cutting process of workpieces on photocurable adhesive layers, leading to inefficient die bonding.
Innovation Solution
A cutting tool with a main body, a cutting layer, and a light emitting material, such as a zinc oxide nano-coating layer, is designed to emit ultraviolet light, curing the photocurable adhesive layer adjacent to the cutting path and reducing contamination, with the cutting layer potentially including diamond particles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional cutting tools are used to cut workpieces on photocurable adhesive layers, then the cutting process can be performed, but adhesive substance attaches to the cutting tool causing contamination and reduced cutting ability
Solution Approach 1:
The patent applies preliminary action by incorporating a light-emitting material into the cutting tool that emits light during the cutting process to pre-cure the photocurable adhesive layer along the cutting path. This preliminary curing action prevents the adhesive from attaching to the cutting tool surface, thereby maintaining cutting ability and preventing contamination before the adhesive can cause harm.
Solution Approach 2:
The light-emitting material acts as an intermediary between the cutting tool and the photocurable adhesive layer. By introducing this intermediary element that emits light, the adhesive is cured in a controlled manner along the cutting path, preventing direct unwanted adhesion to the cutting tool while still allowing the adhesive to perform its bonding function elsewhere.
2Reliability
If the photocurable adhesive layer is cured during cutting, then contamination is reduced, but additional light emitting components increase device complexity
Solution Approach 1:
The patent merges the cutting function and the adhesive curing function into a single integrated tool. The light-emitting material is incorporated directly into the cutting tool structure, allowing both cutting and UV curing to occur simultaneously during one operation, thereby reducing overall process complexity despite adding light-emitting components.
Solution Approach 2:
The cutting tool is designed with multi-functionality by incorporating a light-emitting material that enables it to perform both cutting and adhesive curing functions. This universal tool eliminates the need for separate curing equipment, reducing overall system complexity while maintaining reliable cutting performance.
