Test Equipment & Setup
| Parameter | Detail |
|---|---|
| Test Method | Free-fall drop onto rigid surface, 6 prescribed faces |
| Drop Face 1 | Back face down (背面朝下) |
| Drop Face 2 | Right side face down (右侧面朝下) |
| Drop Face 3 | Front face down (正面朝下) |
| Drop Face 4 | Left side face down (左侧面朝下) |
| Drop Face 5 | Bottom face down (底面朝下) |
| Drop Face 6 | Top face down (上面朝下) |
| Drop Surface | Rigid flat surface (standard drop test platform) |
| Unit Configuration | Bare unit (no packaging) |
| Post-Drop Evaluation | Visual inspection + functional operation check |
Test Procedure
- Pre-Test Inspection: Confirm each sample is fully assembled, free of pre-existing damage, and in normal working condition before testing begins.
- Sample Labeling: Assign and verify unit identifiers: 5#, 6#, 7#, 8#.
- Drop Sequence Setup: Orient the unit to Drop Face 1 (back face down) at the prescribed drop height above the rigid test surface.
- Execute Drop 1 — Back Face Down (背面朝下): Release the unit from the prescribed height without imparting additional force. Allow free fall to the surface.
- Execute Drop 2 — Right Side Face Down (右侧面朝下): Re-orient unit and repeat free-fall drop.
- Execute Drop 3 — Front Face Down (正面朝下): Re-orient unit and repeat free-fall drop.
- Execute Drop 4 — Left Side Face Down (左侧面朝下): Re-orient unit and repeat free-fall drop.
- Execute Drop 5 — Bottom Face Down (底面朝下): Re-orient unit and repeat free-fall drop.
- Execute Drop 6 — Top Face Down (上面朝下): Re-orient unit and repeat free-fall drop.
- Post-Drop Inspection (each face): Immediately after each drop, visually inspect the unit for cracks, housing separation, broken components, or display anomalies. Record findings.
- Functional Verification: After all 6 drops are complete for each unit, power on the device and verify normal inflation functionality.
- Documentation: Record all observations in the test log by sample ID and drop face.
Acceptance Criteria: No functional failure after completion of all 6 drop faces. Minor cosmetic deformation that does not impair function is documented but does not constitute a test failure.
Test Data & Results
| Test Date | Sample ID | Drop 1 — Back Face Down | Drop 2 — Right Side Face Down | Drop 3 — Front Face Down | Drop 4 — Left Side Face Down | Drop 5 — Bottom Face Down | Drop 6 — Top Face Down |
|---|---|---|---|---|---|---|---|
| 2025-08-16 | 5# | No anomaly | No anomaly | Front/rear housing misalignment; function normal | Front/rear housing misalignment; function normal | Front/rear housing misalignment; function normal | Front/rear housing misalignment; function normal |
| 6# | No anomaly | No anomaly | No anomaly | No anomaly | No anomaly | No anomaly | |
| 7# | No anomaly | No anomaly | No anomaly | No anomaly | No anomaly | No anomaly | |
| 8# | No anomaly | No anomaly | Front/rear housing misalignment; function normal | Front/rear housing misalignment; function normal | Front/rear housing misalignment; function normal | Front/rear housing misalignment; function normal |
Observations: Units 5# and 8# exhibited front/rear shell misalignment beginning at Drop 3 (front face down) and persisting through Drops 4, 5, and 6. In both cases, the misalignment was cosmetic — inflation functionality was verified as normal after all drops. Units 6# and 7# showed no anomalies across all six drop faces.
Conclusion
| Item | Detail |
|---|---|
| Test | 6-Face Free-Fall Drop Test |
| Standard / Method | Internal drop test protocol — 6 prescribed faces, bare unit |
| Test Date | 2025-08-16 |
| Samples | 4 units: 5#, 6#, 7#, 8# |
| Functional Result | PASS — All 4 units retained full inflation functionality after completing all 6 drop faces |
| Shell Integrity | NOTED — 2 of 4 units (5#, 8#) showed front/rear housing misalignment from Drop 3 onward; classified as cosmetic, not functional failure |
| Overall Verdict | PASS |

Frequently Asked Questions
Did the ETENWOLF S1 pass the 6-face drop test?
Yes. All four S1 units passed the 6-face free-fall drop test. Every unit retained full inflation functionality after completing drops on all six faces. Two units showed minor front/rear housing misalignment from the front-face drop onward, but this was classified as a cosmetic observation and did not affect function.
What does front/rear housing misalignment mean for the S1?
Front/rear housing misalignment means the two halves of the outer shell shifted slightly out of alignment upon impact. In the S1 drop test, this occurred on units 5# and 8# starting at the front-face-down drop. Critically, functional testing confirmed that inflation performance was unaffected — the device operated normally in all cases.
How many drop faces were tested on the ETENWOLF S1?
Six faces were tested in sequence per unit: back face down, right side face down, front face down, left side face down, bottom face down, and top face down. This covers all principal orientations of the device to simulate realistic drop scenarios during handling and everyday use.
How many S1 samples were used in the drop test?
Four samples were tested, identified as units 5#, 6#, 7#, and 8#. All four completed the full 6-face drop sequence, and all four passed functional verification at the conclusion of the test.
