Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional service robots and pet robots lack realistic and expressive eyes that can simulate the patterns and color changes of human or animal eyes, failing to provide emotional expression and realistic representation.
Innovation Solution
A realistic eyeball design featuring a first lens unit with an inner concave surface, a spherical display unit with a display surface including a pupil and iris area, and a sensing unit positioned corresponding to penetration regions, allowing for pattern and color changes that mimic real eyes and enable emotional expression.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a simple eye pattern or camera is installed in the eye of conventional service robots, then the device complexity is reduced and ease of manufacture is improved, but the realism and emotional expression capability deteriorate
Solution Approach 1:
The eyeball is divided into multiple functional components: a display unit showing eye patterns, a lens unit with specific curvature, and a sensing unit positioned behind the display. This segmentation allows each component to be optimized independently while achieving realistic eye appearance and emotional expression capabilities that simple patterns or cameras cannot provide.
Solution Approach 2:
The display unit is positioned on the inner concave surface of the lens unit, creating a three-dimensional arrangement rather than a flat surface mounting. This spatial arrangement allows light to pass through the display unit and lens unit naturally, achieving realistic eye appearance while maintaining emotional expression capabilities.
2Adaptability or versatility
If a display unit is added to simulate eye patterns and colors, then the emotional expression capability is improved, but the device complexity increases
Solution Approach 1:
The display unit serves multiple functions: displaying eye patterns, showing color changes for emotional expression, and allowing light transmission to the sensing unit behind it. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity while achieving enhanced emotional expression capabilities.
Solution Approach 2:
The lens unit acts as an intermediary between the display unit and the external environment. It focuses light while allowing the display patterns to be visible, mediating between the complex display unit and the simple external observation, thereby reducing the perceived complexity.
3Ease of manufacture
If the display unit is placed on a flat surface, then the ease of manufacture is improved, but the pattern distortion occurs when viewed from outside
Solution Approach 1:
The display unit is positioned on the inner concave surface of the lens unit, following the spherical curvature. This curved surface arrangement ensures that light rays passing through different parts of the display are properly focused, preventing pattern distortion when viewed from outside while maintaining ease of manufacture through standard lens manufacturing processes.
4Manufacturing precision
If the sensing unit is positioned behind the display unit, then the realistic appearance is maintained, but the alignment precision requirement increases
Solution Approach 1:
The sensing unit is nested behind the display unit, with both components positioned within the eyeball structure. The display unit is on the inner concave surface of the lens, and the sensing unit is positioned behind it, aligned with the optical axis. This nested arrangement maintains realistic appearance while the common optical axis alignment simplifies the precision requirements.
