Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices integrated into wearable objects, such as watches, require viewer actions like wrist or head movements to achieve a dynamic display effect.
Innovation Solution
A display device comprising two lenticular gratings, one fixed and one rotating, with aligned focal planes and lens steps, allowing an animated effect without viewer action by using a rotating supporting element like a date disc or indicator organ.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single lenticular grating is used with a static pattern, then the display structure is simple, but the display appears only after viewer action (wrist or head movement)
Solution Approach 1:
The patent introduces a rotating supporting element that rotates around an axis perpendicular to the pattern plane, transforming the static display into a dynamic one. This rotation occurs without requiring viewer movement, automatically creating the dynamic display effect through the interaction between the rotating element and the lenticular grating.
Solution Approach 2:
The invention adds a rotational dimension to the display system by introducing a supporting element that rotates around an axis perpendicular to the pattern plane. This creates a third dimension of movement (rotation rather than just translation or tilting), enabling dynamic display without viewer action.
2Extent of automation
If two lenticular gratings with aligned focal planes are used, then dynamic display appears without viewer action, but the device complexity increases
Solution Approach 1:
The patent combines two lenticular gratings with aligned focal planes and lens steps into a single integrated display system. The first lenticular grating is associated with the rotating supporting element, while the second lenticular grating is associated with the fixed supporting element, creating a coordinated system that produces dynamic display through their combined optical interaction.
Solution Approach 2:
The dual lenticular grating system serves multiple functions: the first lenticular grating works with the rotating element to create dynamic patterns, while the second lenticular grating provides additional optical control and enhancement. This multi-functional arrangement achieves automated dynamic display without requiring excessive complexity in any single component.
3Ease of manufacture
If the pattern is fragmented into straight strips with specific arrangement, then the dynamic effect is enhanced, but the manufacturing precision requirements increase
Solution Approach 1:
The pattern is divided into multiple straight strips arranged in specific groups (first group and second group) with defined spacing and orientation. This segmentation allows the pattern to be fabricated using standard printing or lithography techniques, while the systematic arrangement of strips creates the dynamic visual effect when viewed through the lenticular gratings.
Solution Approach 2:
The patent specifies particular parameters for the strip arrangement including the step between strips, the orientation relative to the lenticular grating lenses, and the grouping of strips into first and second groups. By optimizing these parameters, the system achieves enhanced dynamic effect while maintaining compatibility with conventional manufacturing processes.
