Triangular Blade Unit Lighting for Tape Feeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tape feeding apparatuses face challenges in properly placing lighting units due to spatial design limitations, which can lead to irregular lighting and image quality issues, especially when dealing with curled release papers or tapes.
Innovation Solution
A tape feeding apparatus with a blade unit of triangular pillar shape, featuring a sloped surface and integrated lighting units, including a reflective plate, allows for uniform lighting placement under the blade unit, enabling effective separation and monitoring of tapes while overcoming spatial design constraints.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If lighting units are placed above the tape feeding apparatus, then illumination is provided, but spatial design is constrained and image quality is irregular especially when dealing with curled release papers or tapes
Solution Approach 1:
The lighting unit is inverted from the conventional position above the tape to below the blade unit, allowing light to illuminate the release paper and tape from underneath. This inversion resolves the spatial design constraint by utilizing the space below the blade unit and provides uniform illumination even when the release paper is curled, as the light travels upward through the transparent or translucent blade unit.
Solution Approach 2:
The lighting approach is changed from vertical illumination from above to horizontal illumination from below, utilizing a different spatial dimension. The light passes through the blade unit in the vertical direction, illuminating the tape separation area from a previously unused dimension, thereby overcoming spatial design limitations.
2Illumination intensity
If lighting units are placed above the tape feeding apparatus, then illumination is provided, but image quality becomes irregular when release papers or tapes are curled
Solution Approach 1:
By inverting the lighting position to below the blade unit, the light illuminates the release paper and tape from underneath. When the release paper is curled, this bottom-up illumination ensures that light reaches all areas uniformly, as the curled portions do not block the light path in the same way they would with top-down illumination, thereby maintaining consistent image quality.
Solution Approach 2:
The blade unit itself acts as an intermediary medium for light transmission. Being transparent or translucent, it allows light from below to pass through and illuminate the tape separation area uniformly, mediating between the light source and the tape while ensuring consistent illumination regardless of release paper curling.
3Illumination intensity
If lighting units are integrated into the blade unit, then uniform lighting is achieved, but the device structure becomes more complex
Solution Approach 1:
The lighting unit is merged with the blade unit by integrating the light source into the blade structure itself. This combining of functions allows the blade unit to serve both as a separation tool and as a light-transmitting structure, achieving uniform lighting while maintaining a compact design. The integration is simplified by utilizing the existing blade unit geometry and materials.
