Visual Timing Device Using Red Green LED Signals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Young children, especially toddlers and pre-school age children, have difficulty understanding and adhering to time constraints for daily activities without constant reminders, as they cannot read clocks and are easily distracted, leading to frustration for parents and caregivers.
Innovation Solution
A visual timing device using red and green LED lights, akin to traffic lights, that signals the start and end of activities, accompanied by a console with buttons and an LCD display, allowing children to manage time without reading a clock, with optional audible alarms and safety features to prevent tampering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If clocks and timing devices with alarm functions are used for children, then time management capability is improved, but the device complexity and difficulty of understanding increase for young children who cannot read clocks
Solution Approach 1:
The patent uses color changes (red to green) to represent the passage of time and activity status. The red light indicates activity in progress while the green light signals time is up, providing an intuitive visual indicator system that young children can understand without needing to read clock faces or understand numerical time concepts.
Solution Approach 2:
The patent replaces the mechanical clock face and numerical time display with an optical signal system using LED lights. This substitution transforms the complex mechanical time-telling mechanism into a simple visual signal system that directly communicates time status without requiring the child to interpret numbers or clock positions.
2Reliability
If verbal reminders are used to help children stick to time schedules, then time adherence is improved for older children, but the method is ineffective for toddlers and pre-school age children who cannot read clocks
Solution Approach 1:
The timing device enables children to monitor their own activity time independently without requiring parental intervention or verbal reminders. The visual signals (red and green lights) provide self-service time management, allowing children to understand when to start and stop activities on their own, fostering independence and self-regulation.
Solution Approach 2:
The patent introduces a visual signal intermediary (the traffic light-style indicator) that mediates between the abstract concept of time and the child's understanding. Instead of relying on verbal communication or clock-reading skills, the intermediary visual system directly translates time status into comprehensible visual cues that young children can perceive and respond to.
3Productivity
If constant parental reminders are given to children about time, then time management is enforced, but the child becomes frustrated and the parent loses patience resulting in incomplete chores and tantrums
Solution Approach 1:
The device empowers children to self-monitor their activity time through visual signals, eliminating the need for constant parental reminders. This self-service approach reduces parental involvement to minimal levels while maintaining task completion, thereby preventing the frustration and conflict that arise from repeated verbal reminders and enforcement.

AI summary
A timer device to induce and encourage a young child to manage time when engaged in daily activities, the timer device comprising visually comprehensible changes in time through the use of red and green lights for the start and end of activity period, respectively. The timer device can further include an audible alarm to signal the end of the activity. Further operational switches and buttons include a power button or switch, start/pause button to start time or pause time, engage buttons, hours buttons (+, −) and minutes buttons (+, −) to adjust time on a liquid crystal display (LCD). The timer device can be powered by AC power or battery power.
