Multifunctional Stroller With Sensor-Actuated Lighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing baby strollers pose safety concerns during evening strolls due to reduced visibility for both parents and drivers, as they are difficult to navigate on uneven terrain and increase the risk of pedestrian accidents at night.
Innovation Solution
A multifunctional stroller with rotatable wheels, a seat, and integrated safety features including a light assembly with LEDs, a music playback device, and sensors that automatically toggle between on and off modes using a timer-actuated switch, enhancing visibility and providing entertainment for the child.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a stroller is used during evening hours, then the child can be transported safely, but visibility of the road ahead is reduced making it difficult to navigate uneven terrain
Solution Approach 1:
The light assembly is activated before the parent needs to navigate the stroller in low-light conditions. The sensor detects when it is dark and automatically turns on the lights, preparing the visibility enhancement in advance before any potential hazard occurs.
Solution Approach 2:
The stroller's lighting system is autonomous and self-regulating. The sensor automatically detects ambient light levels and controls the light assembly without requiring parent intervention, allowing the stroller to serve itself by providing illumination when needed.
2Reliability
If a stroller is used during evening hours, then the child can be transported, but the parent and child become less visible to motorists increasing accident risk
Solution Approach 1:
The light assembly emits light that changes the visual appearance of the stroller and its contents. By illuminating the stroller with lights, the parent and child become more visible to motorists, effectively changing the visual characteristics to enhance safety.
Solution Approach 2:
The stroller autonomously provides visibility enhancement without requiring active participation from the parent. The sensor and light assembly work together to automatically make the stroller more visible to drivers, allowing the system to protect itself and its occupants.
3Adaptability or versatility
If safety lights and music devices are added to the stroller, then visibility and entertainment are improved, but the device complexity increases
Solution Approach 1:
The stroller is designed to perform multiple functions: it provides lighting for visibility, plays music for entertainment, and includes sensors for automatic control. By integrating these diverse functions into a single device, the stroller becomes more versatile and adaptable to different needs.
Solution Approach 2:
The patent combines the light assembly, music playback device, sensor, and timer-actuated switch into an integrated system. These separate components work together as a unified multi-functional unit, reducing the need for separate devices and simplifying the overall system architecture.
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 stroller improves safety and visibility for parents and children at night by providing intermittent lighting and entertainment, reducing the risk of accidents and enhancing the overall strolling experience.
Implementation Method 1
A light assembly may be mated to the frame, the wheels and the user interface respectively
Implementation Method 2
A sensor may be attached to the seat and the frame for determining a real-time temperature at the multifunctional stroller
Data Source
AI summary
A multifunctional stroller includes a frame, a user interface, a light assembly, a music playback device, and a timer-actuated switch electrically coupled directly to a power source. Sensors determine a real-time temperature at the multifunctional stroller and are coupled directly to the timer-actuated switch. Such sensors generate and transmit first, second and third input signals to the timer-actuated switch upon detecting first, second and third triggering events respectively. The user interface generates and transmits first and second control signals to the light assembly and the timer-actuated switch respectively upon receiving corresponding user inputs respectively. The timer-actuated switch is toggled to an open position upon receiving at least one of the first, second and third input signals within a first time period after receiving the second control signal so that power is transmitted to the music playback device for a second time period.
