Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional analogue watch movements are limited in design and do not offer an alternative to the traditional circular face with hour, minute, and second hands, which can be aesthetically and functionally monotonous.
Innovation Solution
A timepiece design featuring a base layer with first time information, a rotatable hand with distinct portions, a second layer with second time information, and a drive mechanism that aligns the second time information with the hand, utilizing intermediate and top layers for enhanced visibility and contrast, allowing for a unique and stylish presentation of time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional circular face with hour, minute, and second hands is used, then the timepiece maintains traditional functionality, but the design becomes aesthetically and functionally monotonous
Solution Approach 1:
The timepiece face is segmented into multiple functional layers: a base layer with first time information (hours), a rotatable second layer with second time information (minutes), and a hand assembly with distinct portions. Each layer serves a specific time-telling function, allowing the design to depart from traditional monolithic circular faces while maintaining readability.
Solution Approach 2:
The patent introduces rotational movement of the second layer relative to the base layer, adding a dimensional aspect to time display. Instead of all time information being static on a single plane, the minutes are displayed through rotational alignment, creating a dynamic multi-dimensional interface.
2Illumination intensity
If multiple layers with time information are introduced, then visual appeal and readability are enhanced, but the device complexity increases
Solution Approach 1:
The hand assembly features local differentiation with a first portion (hour hand) and a second portion (minute hand) that extend in different directions from the connection point. The second layer is designed with transparent or translucent regions to allow visibility of underlying time information, creating local variations in optical properties to enhance readability.
Solution Approach 2:
The drive mechanism acts as an intermediary between the user's manual input (rotating the second layer) and the time display function. It translates rotational movement into precise alignment of the second time information with the corresponding portion of the hand, mediating the interaction between user action and visual output.
3Loss of information
If the second layer is made transparent or translucent to show underlying time information, then visibility is improved, but the contrast and prominence of the second time information may be reduced
Solution Approach 1:
The second layer employs local quality variations with specific transparent or translucent regions that allow visibility of underlying time information only where needed. This selective transparency ensures that the second time information remains prominent in its designated sector while allowing the first time information to show through in other areas, optimizing both visibility and contrast locally.

AI summary
A timepiece comprising: a base layer, which has first time information presented thereon; a hand which is rotatable with respect to the base layer about a connection point, the hand having a first portion which extends away from the connection point in a first direction, and a second portion which extends away from the connection point in a second, different direction; a second layer which is mounted for rotational motion with respect to the base layer, the second layer having second time information presented thereon; and a drive mechanism which is operable to drive rotation of the second layer with respect to the base layer such that a desired part of the second time information presented on the second layer is aligned with the second portion of the hand.
