Lenticular Lens Recording Guide with Convex Portions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing recording apparatuses face challenges in achieving precise positioning of lenticular images on lenticular lenses due to the need for costly sensors and degradation of precision when the transport tray is inclined, leading to position deviations and reduced image recording accuracy.
Innovation Solution
A recording apparatus with a transport mechanism and a guide featuring convex portions along the transport direction, which guides the recording medium by contacting the lenticular lens, ensuring precise alignment and preventing skewing through a pressing member, such as a transport roller, to maintain accurate image positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a sensor is used to detect the position of the lenticular lens, then the position detection accuracy is improved, but the apparatus cost increases
Solution Approach 1:
The lenticular lens itself serves as the positioning reference by utilizing its inherent periodic structure. The guide's convex portions engage with the lenticular lens ridges, allowing the lens to self-align and self-position without requiring external sensors or detection systems. This eliminates the need for separate position detection apparatus while maintaining positioning accuracy.
Solution Approach 2:
The guide with convex portions acts as an intermediary mechanism between the transport system and the lenticular lens. Instead of directly detecting lens position with sensors, the guide physically mediates the positioning by engaging the convex portions with the lenticular lens structure, translating the lens's periodic features into precise positional alignment.
2Speed
If the transport tray is inclined to transport the recording medium, then the transport speed is improved, but the recording position precision is degraded
Solution Approach 1:
The convex portions of the guide are designed with curved surfaces that match the periodic curvature of the lenticular lens ridges. This curved geometry allows the guide to maintain continuous contact and engagement with the lenticular lens during transport, ensuring that the lens remains properly aligned even during inclined or accelerated movement, thus preserving recording position precision.
Solution Approach 2:
The guide features multiple discrete convex portions distributed along its length, each engaging with corresponding ridges of the lenticular lens. This segmentation allows the guide to maintain positioning control at multiple points during transport, preventing cumulative positioning errors that would otherwise occur during inclined transport.
