Rotating Mechanical Clock With Static Hand And Lightweight Disks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mechanical clocks and watches rely on rotating hands to indicate time, which can be complex and prone to mechanical wear, limiting their longevity and requiring frequent battery changes or winding.
Innovation Solution
A mechanical clock mechanism using rotating concentric circular disks with a static hand, where gears rotate the disks around a common axis to indicate hours, minutes, and seconds, utilizing lightweight materials and balanced weight distribution to reduce energy consumption and extend operational time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If rotating hands are used to indicate time, then time can be displayed, but mechanical wear increases and operational life decreases
Solution Approach 1:
Instead of rotating the hands to indicate time, the patent inverts the approach by keeping the hand stationary and rotating the clock face itself. This inversion eliminates the mechanical wear that occurs at the hand's rotation point while maintaining the time-display function through the rotation of numbered disks.
Solution Approach 2:
The clock face is segmented into multiple concentric disks, each representing different time units (hours, minutes, seconds). These segmented disks can rotate independently around a stationary hand, distributing the mechanical stress and enabling precise time measurement without overloading a single rotating component.
2Loss of information
If multiple rotating hands are used to indicate different time units, then complete time information is displayed, but device complexity increases
Solution Approach 1:
Multiple time-display functions (hours, minutes, seconds) are merged into a single rotating mechanism system. Instead of three separate hands requiring three independent rotation mechanisms, the patent combines them into one rotating assembly of concentric disks that all rotate around a single stationary hand, significantly simplifying the gear train and mechanical structure.
Solution Approach 2:
The stationary hand serves multiple functions simultaneously - it acts as the reference pointer for all three time units (hours, minutes, seconds) displayed on the rotating disks. This universal reference point eliminates the need for multiple hands, each requiring its own balancing and bearing system.
3Strength
If heavy materials are used for rotating components, then structural strength is maintained, but energy consumption increases
Solution Approach 1:
The patent employs thin, lightweight disks to represent the clock face segments. These thin-film structures provide sufficient structural integrity for displaying time information while dramatically reducing the mass that needs to be rotated, thereby minimizing the energy required for the gear mechanism to operate the rotating disks.

AI summary
A rotating mechanical clock or watch with a static hand for telling time for hours, minutes, and seconds. The rotating mechanical clock permits telling time using gears and powered by a battery or winding mechanism. Instead of using the rotating hands of a standard mechanical clock, light-weight balanced rotating disks tell the time under one static hand for easy display and reading.
