Single-Hand Timepiece with Counter-Rotating Minute Disc
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional timepieces require users to separately locate and interpret hour and minute hands, which can be cumbersome and less efficient for quickly determining time.
Innovation Solution
A single-hand timepiece that rotates at the speed of an hour hand, with a minute disc rotating in the opposite direction, allowing the single hand to simultaneously indicate both hour and minute by aligning with static hour indicia and radially disposed minute indicia on the face.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional timepieces use separate hour and minute hands, then the time can be identified, but the user must separately locate and interpret both hands which increases operational complexity and reduces efficiency
Solution Approach 1:
The patent merges the functions of hour hand and minute hand into a single hand that performs both functions. The single hand rotates once per hour and its position relative to hour markers indicates hours, while its position relative to minute markers indicates minutes, eliminating the need for separate hands and simplifying the reading process
Solution Approach 2:
The single hand is designed to serve multiple functions simultaneously - it acts as both an hour indicator and a minute indicator. By rotating once per hour and interacting with both hour markers and minute markers on the dial, the single hand provides universal time-telling functionality that replaces the traditional two-hand system
2Measurement precision
If a single hand rotates once per hour to indicate hours, then the hour indication is clear, but the minute indication requires additional mechanisms
Solution Approach 1:
The patent introduces minute markers on the dial as an intermediary element that enables minute indication without requiring a separate minute hand. The single hand's position relative to these minute markers provides precise minute information, while the markers themselves serve as the mediating reference system that translates the hand's position into minute readings
3Shape
If the single hand rotates at hour hand speed, then the design remains classic and elegant, but simultaneously identifying both hours and minutes requires innovative mechanisms
Solution Approach 1:
The patent adds a temporal dimension to the single hand's rotation by having it complete one full rotation every hour rather than every minute. This dimensional change in rotation speed allows the hand to indicate hours through its position relative to hour markers while simultaneously indicating minutes through its position relative to minute markers, maintaining classic aesthetics while enabling dual-functionality

AI summary
A single-hand or single-indicator timepiece that can simultaneously identify both the hour and minute portion of a given time is present herein. The timepiece includes an indicator structured to rotate about the face of the timepiece and point to the hour element of the time via a distal end thereof. In addition, the same indicator includes a minute identifying portion disposed along a length thereof that will align with a rotationally disposed minute disc. The minute disc includes indicia representative of the minutes evenly spaced radially about its surface in a clockwise ascending order. As the minute disc rotates counterclockwise and the indicator rotates clockwise, the indicator will simultaneously identify the hour element at its distal end and the minute element via the relative position of the minute identifying portion and the minute disc.
