Mobile Toilet Research Questionnaire

The mobile toilet research questionnaire can be designed around aspects such as usage needs, functional design, price acceptability, usage scenarios, and special requirements. Below is the specific content:

---

I. Usage Needs and Preferences

1. Necessity of Use: Inquire whether there is a need to use mobile toilets during outdoor activities, travel, or in specific scenarios (such as music festivals, construction sites) to clarify users' basic needs for mobile toilets.
2. Type Preferences: For public scenarios, investigate users' acceptance of sit-down or squat toilets; for portable scenarios, understand users' concerns about the portability and weight limits of foldable portable toilets (such as "whether weight limits are a concern" and "the importance of portability").
3. Privacy and Safety: Assess users' needs for privacy protection (such as "whether they accept unisex toilets" and "whether they are concerned about safety issues") and whether they require safety features such as emergency assistance buttons.

II. Functional and Design Requirements

1. Core Functions: Investigate users' expectations for hygiene-related functions such as ventilation and odor removal, waterproofing and leakage prevention, and ease of cleaning and maintenance, as well as whether they require additional functions such as independent power supply (such as solar energy) and disposable use.
2. Comfort: Understand users' requirements for design details such as seat comfort, space stability, and material texture (such as "requirements for design and comfort").
3. Smart Needs: For tourism scenarios, inquire whether they need smart services such as electronic map toilet location and instant shopping platforms (selling tissues, skincare products, etc.), as well as whether they accept 24-hour operation.

III. Price and Quality Considerations

1. Price Range: Investigate the acceptable price ranges for users in different scenarios (such as portable toilets ranging from "10-50 yuan" to "over 200 yuan", and public toilets ranging from "0-100 yuan" to "over 1000 yuan").
2. Quality and Durability: Understand users' concerns about product durability (such as "whether they are worried about quality issues") and whether they are willing to pay a premium for higher quality (such as "whether they are willing to pay higher fees").

---

IV. Usage Scenarios and User Groups

1. Applicable Scenarios: Clarify the main usage occasions for mobile toilets, such as camping, music festivals, construction sites, and emergency rescue (such as "which occasions they think are useful" and "which occasions they are more inclined to use").
2. User Groups: Distinguish the needs of different occupational or hobby groups (such as outdoor enthusiasts, travelers, construction workers) and special needs (such as accessible toilets and suitability for the elderly).

---

V. Environmental Protection and Aesthetic Needs

1. Environmental Protection Concept: Investigate users' acceptance of environmentally friendly designs such as water and electricity conservation, recyclable materials, and recycled paper (such as "whether they support recycled paper" and "whether they need high-efficiency and low-pollution designs").
2. Exterior Design: Understand users' preferences for aesthetic styles such as simplicity, modernity, and nature (such as "aesthetic concepts").

VI. Other Suggestions Open-ended questions to collect users' suggestions for improving mobile toilets (such as "other functions or features" and "other suggestions") to improve product design.
