Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a watch uses conventional static decorations on the dial and bezel, then the manufacturing is simple and reliable, but the visual appearance is not unique or particularly attractive
Solution Approach 1:
The patent applies the dynamics principle by transforming static decorative elements into dynamic visual displays through a rotating disc with moiré patterns. The disc rotates along with the seconds hand, creating animated sequential images that change over time, thereby providing unique and attractive visual appearance while maintaining compatibility with conventional watch movements
Solution Approach 2:
The patent utilizes parameter changes by varying the rotational position of the disc to generate different moiré effect images. As the disc rotates, the interference pattern between the fixed graphic representation and the rotating pattern creates a sequence of distinct images, achieving visual versatility through parameter variation rather than structural complexity
2Adaptability or versatility
If a watch incorporates animated complications or decorative elements, then the visual appeal and notoriety are enhanced, but the device complexity increases
Solution Approach 1:
The patent applies universality by designing a multi-functional system where the existing seconds hand mechanism serves dual purposes: its primary function of indicating time and its secondary function of rotating the decorative disc to create animations. This allows the watch to generate visual appeal without requiring separate dedicated animation mechanisms, thereby avoiding increased device complexity
Solution Approach 2:
The patent implements self-service by utilizing the kinetic energy already present in the watch movement to drive the animation system. The seconds hand's natural rotation automatically drives the disc without requiring additional power sources or complex control mechanisms, allowing the decorative element to serve itself using the watch's existing operational energy
3Reliability
If a watch uses existing conventional watch movement without modifications, then the reliability and ease of manufacture are maintained, but the ability to generate high-speed animation is limited
Solution Approach 1:
The patent applies periodic action by utilizing the regular, periodic rotation of the seconds hand (completing one revolution per minute) to drive the animation sequence. The moiré effect disc is designed to generate a complete sequence of distinct images within each rotation cycle, ensuring that the animation plays out in a consistent, repeating pattern that maintains reliability while achieving the desired animation speed
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution creates a high-speed animation that enhances the watch's visual appeal without requiring significant modifications to existing watch movements, allowing for dynamic and attractive sequential animations.
Implementation Method 1
The pattern and the graphic representation are shaped so that, during rotation of the arbor, they cooperate with each other in order to generate a sequential animation by moiré effect formed by a sequence of at least two distinct images
