Baby Carriage Wheel Brake Linkage for Simple Dual-Wheel Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing baby carriage braking mechanisms are complex in structure and inconvenient to operate, requiring multiple mechanisms for effective braking.
Innovation Solution
A simple braking mechanism with a driving member and locking member, where the driving member is pivotally connected to the wheel seat and includes a driving slot and guiding opening, allowing the locking member to engage or disengage with the wheel hub through rotation, facilitated by an elastic member and pushing member for easy operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a braking mechanism locks a single wheel, then the structure is simpler, but two braking mechanisms are needed to brake two rear wheels, increasing overall complexity
Solution Approach 1:
The patent merges the functions of locking multiple wheels into a single braking mechanism. The driving member is pivotally connected to the wheel seat and controls a locking member that can simultaneously engage with engaging parts on multiple wheel hubs. This allows one braking mechanism to lock multiple wheels at the same time, eliminating the need for separate braking mechanisms for each wheel while maintaining simple structure and convenient operation.
2Ease of operation
If a braking mechanism locks two wheels at the same time, then the operation is more convenient, but the structure becomes complex
Solution Approach 1:
The braking mechanism is designed with multi-functionality where the driving member serves multiple purposes: it controls the locking member to engage or disengage from multiple wheel hubs simultaneously. The driving slot and guiding opening configuration allows the locking member to interact with multiple engaging parts through a single rotational motion of the driving member, achieving universal wheel locking capability without complex multi-component systems.
3Adaptability or versatility
If multiple braking mechanisms are used to lock individual wheels, then each wheel can be controlled independently, but the overall device complexity increases
Solution Approach 1:
The braking mechanism employs dynamic design where the locking member can selectively engage with different engaging parts on different wheel hubs based on the rotation angle of the driving member. The driving slot and guiding opening configuration enables the locking member to dynamically adjust its position and engage with the appropriate wheel hub, providing adaptable wheel control through a single unified mechanism rather than multiple fixed mechanisms.
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 braking mechanism provides a straightforward operation by rotating the driving member to lock or unlock the wheel, ensuring safety and convenience while preventing accidental movements.
Implementation Method 1
the elastic member is arranged between the wheel seat and the locking member and configured to provide an elastic force to force the locking member to exit the engaging part
