4. Production Process
Stage 1: Material Preparation
- Procure high-quality materials resistant to corrosion and capable of bearing load stresses.
- Test all materials for compliance with safety and durability standards.
Stage 2: Component Manufacturing
- Fabricate hollow interlocking metal sections to the specified size (20-30 cm).
- Manufacture spring mechanisms and test their tensile strength.
- Mold hand grips and padding to ensure comfort and durability.
Stage 3: Assembly
- Assemble the interlocking metal sections with the spring mechanism to allow seamless folding.
- Attach adjustable hand grips with secure locking mechanisms.
- Fit ergonomic padding for comfort during prolonged use.
Stage 4: Quality Testing
- Conduct load tests to verify weight-bearing capacity and durability.
- Test height and grip adjustments for secure locking and ease of use.
- Perform stress tests to ensure the crutch withstands long-term use.
Stage 5: Packaging and Distribution
- Clean and sterilize crutches before packaging.
- Package crutches in protective coverings with user manuals.
- Distribute to hospitals, clinics, and retail stores.
5. Quality Control Measures
- Material Durability: Verify strength and resistance to environmental factors.
- Ergonomic Comfort: Test user comfort over extended periods.
- Load Testing: Ensure crutches can bear a load exceeding user weight by at least 25%.
- Safety Standards: Comply with ISO standards for design and risk management.
6. Scope
The production plan is focused on:
- Manufacturing foldable crutches for individuals with temporary or long-term mobility challenges.
- Providing a compact, portable solution for frequent travelers and healthcare providers.
- Supplying crutches to hospitals, clinics, and retail stores globally.
7. Limitations
