Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in efficiently printing light-blocking portions and ensuring accurate adhesion between window members and case members, particularly in bent edge portions, which affect process efficiency and aesthetics.
Innovation Solution
A printing apparatus with detachable outer and inner jigs and a print head, utilizing magnets or protrusions/recesses for coupling, allows for precise alignment and printing on window members, enhancing process efficiency and accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed jig structure is used, then structural stability is maintained, but adaptability to different window member shapes is reduced
Solution Approach 1:
The jig is divided into an outer jig and an inner jig that can be separately replaced. The inner jig can be detached from the outer jig and replaced with a different inner jig to accommodate different window member shapes, while the outer jig remains unchanged. This segmentation allows adaptability without increasing overall system complexity.
2Adaptability or versatility
If the inner jig is permanently fixed, then alignment stability is improved, but flexibility for different printing positions is reduced
Solution Approach 1:
The coupling between the outer jig and inner jig is made detachable through coupling portions that can be connected or disconnected. This dynamic connection allows the inner jig to be replaced for different printing positions while maintaining stable alignment during each printing operation through the secure coupling mechanism.
3Adaptability or versatility
If the pad portion is fixed to the print head, then printing consistency is maintained, but adaptability to different window member surfaces is reduced
Solution Approach 1:
The pad portion is separated from the print head, allowing the pad portion to be independently replaced. Different pad portions can be selected to match different window member surfaces (e.g., flat surfaces, bent edges), while the print head remains unchanged. This maintains printing consistency through proper pad selection without requiring a fixed universal pad.
4Productivity
If a single jig design is used, then device simplicity is maintained, but productivity due to interchangeable components is reduced
Solution Approach 1:
The outer jig serves as a universal base that can accommodate multiple different inner jigs. The coupling portions are designed to work with both the outer jig and various inner jigs, creating a multi-functional system where a single outer jig design supports multiple printing configurations through interchangeable inner jigs, thereby improving productivity without proportionally increasing complexity.

AI summary
A printing apparatus includes, an outer jig comprising an outer wall portion and a recessed portion, an inner jig disposed in the recessed portion and forming a hole between the outer wall portion and the inner jig, and a print head comprising a pad portion configured to overlap the hole, wherein the outer jig comprises an outer coupling portion disposed adjacent to a first surface of the outer jig facing the inner jig, the inner jig comprises an inner coupling portion disposed adjacent to a second surface of the inner jig facing the outer jig, and the outer jig and the inner jig are detachable from each other by detachment of the outer coupling portion and the inner coupling portion from each other.
