International Pet Stroller Brand Boosts Convenience with UJEN Pull Pin Spring Knob Quick-Connection Module

This case describes how an internationally renowned pet stroller brand used UJEN pull pin spring knob technology to upgrade the connection between the pet carrier and the stroller frame. The brand needed a quick-connection device that was stable, easy to operate, and suitable for frequent use. Traditional connection methods were time-consuming, unstable, and generated higher after-sales costs. By adopting a custom quick-assembly module built around UJEN pull pin spring knobs, the client achieved faster installation and removal, improved stability, and more efficient maintenance, significantly enhancing product convenience, user experience, and overall market competitiveness.

Client Background｜Pull Pin Spring Knob Requirements for a Leading Pet Stroller Brand

The client is an internationally recognized pet stroller brand dedicated to designing and manufacturing high-quality, safe, and user-friendly products for pets and their owners. With products sold in more than thirty countries, the brand focuses on comfort, safety, and everyday convenience, continuously upgrading its stroller platforms to match modern lifestyle expectations and global market demands.

Problem Description｜Limitations of Traditional Connection Methods

While developing its latest pet stroller series, the brand needed a mechanism that could quickly connect and disconnect the pet carrier while maintaining stability during movement. Traditional connection methods were slow to operate, required multiple steps, and were prone to loosening over time. These issues negatively affected the product’s user experience, increased after-sales service pressure, and raised maintenance costs.

Solution｜Quick-Assembly Module Using UJEN Pull Pin Spring Knob Technology

After in-depth product analysis and comparison of different fastening solutions, UJEN developed a dedicated quick-assembly module based on pull pin spring knobs for the brand’s pet stroller platform. The module allows the pet carrier to be quickly and securely attached to the stroller frame, forming a reliable quick-connection interface between the two structures.

• Pull pin spring knob used as the core quick-connection component
• Carrier can be locked firmly onto the stroller frame with simple operation
• T-shaped handle design enables easy pulling and lifting when detaching the carrier
• Modular structure supports future upgrades and variant models

Ultimately, the brand selected UJEN’s pull pin spring knob module as the standard quick-connection device for this stroller series.

Implementation Process｜Applying Pull Pin Spring Knobs in Product Design

UJEN’s engineering team collaborated closely with the client’s product development department to ensure that the pull pin spring knob module integrated seamlessly with the stroller structure.

• Reviewed stroller frame design and carrier geometry to define mounting points
• Provided multiple pull pin spring knob samples and variants for testing
• Optimized dimensions, tolerances, and handle design based on feedback
• Validated stability and ease of operation through repeated user simulations

Through several rounds of optimization, the final solution achieved a precise fit with the stroller system and met the client’s performance expectations.

Results and Effectiveness｜Enhancing Efficiency and Stability with Pull Pin Spring Knobs

By applying UJEN pull pin spring knob technology, the brand significantly improved both product efficiency and user satisfaction.

• Improved ease of operation: Users can install or remove the pet carrier quickly and intuitively, shortening setup time and making everyday use more convenient.
• Increased product stability: The robust pull pin spring knob design secures the carrier firmly to the stroller, enhancing safety during walking and transport, and reducing the risk of accidental detachment.
• Easier repair and replacement: The modular quick-connection design simplifies component replacement and maintenance, helping the brand save time and service costs.
