1. Product Design Flaws**
– **Poor Leak-Guard Design**:
– Low-height or stiff leak-guard edges fail to conform to a baby’s leg contours, causing gaps.
– *Fix*: Use elastic materials (e.g., Lycra) and 3D tailoring for dynamic fit.
– **Uneven Absorbent Core Distribution**:
– Superabsorbent polymer (SAP) concentrated in the center leads to lateral leakage when lying sideways.
– *Fix*: Reinforce side absorbency with layered cores or dual-channel wicking.
—
2. Incorrect Sizing**
– **Mismatched Size/Weight**:
– Too loose (gaps at legs) or too tight (compression leaks).
– *Fix*: Provide detailed size charts and sample packs.
– **Unisex Designs**:
– Generic diapers may not account for gender-based wetting patterns.
– *Fix*: Gender-specific designs (e.g., front-heavy for boys, wider middle for girls).
—
3. User Errors**
– **Improper Wear**:
– Un-tucked leak guards, asymmetrical fastening, or incorrect waist tightness.
– *Fix*: Add visual guides/QR codes linking to tutorial videos.
– **Delayed Changes**:
– Over-saturation reduces absorption capacity.
– *Fix*: Highlight wetness indicators and recommend 2–3 hour changes.
—
4. Material & Manufacturing Issues**
– **Breathability vs. Absorption Trade-off**:
– Overly breathable topsheets may slow liquid diffusion.
– *Fix*: Use textured surfaces (e.g., 3D embossing) for rapid liquid intake.
– **Quality Control Lapses**:
– Misaligned cores or weak seam adhesions in production.
– *Fix*: Implement pressure tests and batch tracking.
—
5. Unaddressed Usage Scenarios**
– **Nighttime/Active Use**:
– Frequent movement (rolling/crawling) increases lateral pressure.
– *Fix*: Launch “overnight” or “active-fit” variants with enhanced waistbands.

Key Recommendations
– **Education**: Simplify instructions with icons/videos.
– **R&D Focus**: Analyze returns to prioritize high-leak sizes (e.g., L/XL).
– **Customer Service**: Offer free replacements for defective batches.
By addressing design, sizing, user habits, and production rigor, brands can significantly reduce leakage complaints and improve trust.
