Helping a Korean Trader Reduce Tripod Fan Defect Rate from 8.1% to 0.6% and Boost Positive Review Rate to 96.8%

Client Background

Client Type: Trader
Target Market: South Korea (Outdoor camping & market stall scenarios)
Initial Requirement: Customize a structurally stable tripod portable fan with batteries compliant with Korean KC certification standards, for sale in outdoor camping and market stall scenarios in South Korea.

Collaboration Challenges

Poor Structural Stability: The original supplier’s tripod support structure was weak, causing the fan to wobble easily when placed on the ground. Negative user reviews primarily focused on "unstable" and "easily toppled over."
Lack of Battery Compliance: The lithium battery had not passed the mandatory Korean KC 62133-2 certification, preventing entry into mainstream sales channels and posing safety risks.
High Quality Fluctuation in Mass Production: The defect rate of mass-produced batches reached as high as 8.1%, and returns and after-sales costs continuously eroded profits.

Hebron Solutions

Solution 1: Early Intervention by Structural & Mold Engineers for Optimization (→ Advantage #2 Custom Design Capability)

Structural simulation verification was integrated during the ID review phase. The tripod’s support angle and weight distribution were redesigned, and key connection nodes were reinforced. Ground stability improved by 40%, completely resolving the wobbling issue.

Solution 2: Selection of Compliant Cells + Full KC Certification Implementation (→ Advantage #5 Multi-Country Certification Experience)

Cells already holding KC 62133-2 certificates were selected, paired with a self-developed two-stage BMS protection design, passing the mandatory Korean battery certification in one attempt. The complete unit also passed KC 60335-2-80 safety testing, ensuring zero barriers to channel access.

Solution 3: Full-Process Reliability Testing + Batch Quality Control (→ Advantage #7 Comprehensive Quality Control System)

12 reliability tests including drop, aging, and vibration tests were conducted for each batch. Statistical Process Control (SPC) was established for critical processes, keeping mass production consistency deviation within ±0.5%, eliminating quality fluctuations at the root.

Collaboration Results

Product defect rate dropped from 8.1% to 0.6% , a reduction of 92.6%.
Positive review rate for the product in the Korean outdoor market increased from 91.5% to 96.8% .
Collaboration has lasted for 2 years , with the client continuously placing new product orders annually.
Stable batch shipments achieved, with no channel rejections due to quality or certification issues.
