1. Folding Mechanism
- The crutches are constructed with a collapsible frame that allows the sections to fold compactly.
- *Functionality:* Users can open or fold the crutches by unlocking sections via detent buttons. The folding mechanism likely uses a hinge system or telescoping joints for smooth operation.

2. Adjustable Height
- Detent Buttons: These buttons allow users to adjust the height of both the handle and the crutch leg sections. By pressing the buttons, the user can slide the sections to the desired position and lock them in place.
- Benefit: This ensures the crutches can accommodate users of varying heights.

3. Detachable Parts
- The lower tip section can be removed or reassembled by rotating and sliding out, as shown in the steps. This feature makes it easy to replace parts if needed and contributes to the crutch’s compactness.

4. Durable Materials
- The use of aluminum (possibly 6061-T6) ensures the crutches are lightweight yet strong enough to bear the user’s weight, making them easy to carry and maneuver.

5. Ergonomic Design
- Handles and armpit supports are padded for user comfort during extended use.
- The rubber tips provide grip and stability on different surfaces, reducing the risk of slipping.
