Electric Ride-on Vehicle Safety Control via Divider Switch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ride-on children's toys lack effective safety features to prevent accidental movement while children are playing in the vehicle's rear compartments, posing a risk of injury.
Innovation Solution
A moveable divider mechanism is integrated between the front and rear compartments of the electric toy vehicle, which must be in a lowered position for the vehicle to operate, ensuring that children cannot play in the rear compartment when the vehicle is in motion by preventing motor operation unless the divider is lowered, thus ensuring safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a moveable divider mechanism is integrated to prevent motor operation when children are in the rear compartment, then safety is improved, but device complexity increases
Solution Approach 1:
The switch mechanism is integrated within the moveable divider structure itself. The divider panel contains a recessed switch that is actuated by the divider's movement, nesting the safety control function within the existing divider component rather than adding a separate control system.
Solution Approach 2:
The divider mechanism automatically controls motor operation through its own position. When the divider is moved to block rear compartment access, it automatically triggers the switch to prevent motor operation, eliminating the need for separate safety controls or manual intervention.
2Reliability
If the divider must be in a lowered position for vehicle operation, then safety is improved, but ease of operation deteriorates
Solution Approach 1:
The switch is positioned to be actuated in advance by the divider's movement. As the divider is moved to its operational position, it automatically triggers the switch before the vehicle can be operated, ensuring safety conditions are met before operation begins.
Solution Approach 2:
The switch acts as an intermediary between the divider position and motor operation. The divider's physical position is translated into an electrical signal through the switch, which then controls motor operation, creating a safe intermediary control mechanism.

AI summary
An electric toy vehicle includes a vehicle body having a front compartment and a rear compartment. A set of surface engaging members is rotatably connected to the vehicle body. A motor is operatively connected to the surface engaging members. A moveable divider is positioned between the front compartment and the rear compartment. The divider is moveable between a first position and a second position. A switch includes a first state and a second state. When the divider is in the first position the switch is in the first state and when the divider is in the second position the switch is in the second state. When the switch is in the first state, the motor is prevented from operating the surface engaging members.
