Stroller Wheel Locking Structure With Single-Press Pedal Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing child stroller wheel locking mechanisms require two separate actions, an upward and a downward motion, which are inconvenient and can cause damage or staining to the user's instep, especially when wearing shoes with exposed insteps.
Innovation Solution
A parking structure with a locking structure that can switch between locked and released positions through a single, unilateral pedal operation, utilizing a drive structure that performs a reciprocating motion to automatically transition between locked and released states, incorporating a braking part, clamping part, and actuating part to facilitate smooth and damage-free wheel locking and unlocking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional locking mechanism with upward and downward actions is used, then the wheel can be locked and unlocked, but the operation becomes inconvenient and can damage or stain the user's instep
Solution Approach 1:
The patent inverts the traditional locking mechanism by using a single downward pressing motion instead of requiring both upward and downward actions. The pedal is designed such that pressing it downward simultaneously performs both the locking and unlocking functions through the reciprocating motion mechanism, thereby eliminating the harmful upward action that could damage the instep while maintaining operational convenience
2Ease of operation
If a single unilateral pedal action is used, then operation convenience is improved, but the locking mechanism becomes more complex
Solution Approach 1:
The patent merges the locking and unlocking functions into a single pedal pressing action. The drive structure integrates multiple functional elements (braking part, clamping part, actuating part) that work together through one reciprocating motion, allowing both locking and unlocking to be achieved by a single downward press, thus simplifying user operation while managing internal complexity through functional integration
Solution Approach 2:
The locking mechanism is designed to automatically perform the locking and unlocking actions through the reciprocating motion generated by the single pedal press. The drive structure self-regulates the sequence of operations (braking part moving, clamping part blocking/unblocking) without requiring additional user input or complex control systems, maintaining operational simplicity while achieving reliable locking functionality
Data Source
AI summary
The application discloses a parking structure including: a locking structure, capable of switching between a locked position that prevents a wheel from rotating and a released position that allows the wheel to rotate; and a drive structure, connected to the locking structure; wherein the drive structure is capable of being driven from an initial position to an active position, and automatically returning from the active position to the initial position, so as to perform a reciprocating motion, and one reciprocating motion of the drive structure causes the locking structure to switch from the released position to the locked position or from the locked position to the released position. A child stroller is also disclosed.
