4.3 Selling Point vs. Decision Driver Alignment

4.3.1 Alignment Analysis

Core selling points (waterproofing, machine-washability, durability) align well with users' primary decision factors. However, several communication gaps persist: 1. Waterproof Performance vs. Reality: Claims of 'waterproofing' conflict with user-reported leakage, indicating unmet expectations of true impermeability. 2. Material Texture Misrepresentation: Descriptions of 'luxurious fabrics' contradict 'plastic-like' experiences in reviews. 3. Insufficient Mildew Resistance Emphasis: While 'machine-washable' is highlighted, actual mold prevention capabilities remain under-communicated. 4. Underutilized Innovations: Removable liners, hookless systems, and light-permeable designs lack consistent category-level promotion despite solving documented pain points.

4.3.2 Key Findings

Users expect exceptional waterproofing and mildew resistance, with performance gaps driving dissatisfaction. Negative reviews center on leakage and mold issues, directly affecting brand reputation and repurchase rates.
Blurring lines between decorative and functional curtains elevate demand for aesthetic-utility combinations. While 2-in-1 products emerge, core functionality remains the primary decision driver with aesthetics as differentiators.
Innovative designs (hookless, removable liners, light-permeable tops) significantly enhance satisfaction. Solving installation, cleaning, and lighting pain points enables premium pricing and attracts quality-focused buyers.
Material sensory experience (odorless, fabric-like feel, softness) critically influences satisfaction. Premium material claims elevate brand perception, attract discerning customers, and reduce odor-related returns.
