FTH, abréviation de Failure to Hold (échec de maintien), est un terme technique couramment utilisé dans l'industrie manufacturière, en particulier dans le contexte de l'assemblage de tétines/poches latérales. Il décrit un type d'échec spécifique qui se produit lorsqu'une tétine, qui est une petite pièce saillante, est incapable de se fixer correctement dans une poche latérale, un creux ou une cavité conçu pour la recevoir.
Comprendre le FTH
La cause première du FTH peut varier en fonction de l'application spécifique. Voici quelques facteurs courants :
Conséquences du FTH
Le FTH peut avoir des conséquences graves, en fonction du produit et de son utilisation prévue. Cela inclut :
Prévenir et Atténuer le FTH
Pour prévenir et atténuer le FTH, les fabricants peuvent utiliser diverses stratégies :
FTH : Une Considération Critique
Le FTH est une considération cruciale pour les fabricants de tous les secteurs. En comprenant les causes, les conséquences et les méthodes de prévention du FTH, les entreprises peuvent améliorer la fiabilité des produits, renforcer la sécurité et minimiser les coûts de production.

Scenario: You are working in a factory that manufactures automotive parts. One of the products is a fuel pump assembly that uses a nipple to connect the fuel line to the pump. Recently, there has been a rise in FTH issues with this assembly, leading to fuel leaks and potential safety hazards.
Task: Identify three potential causes of the FTH issue and propose specific solutions for each cause.
Here are some possible causes and solutions:
Cause 1: Improper fit between the nipple and sidepocket: * Solution: Implement a more rigorous inspection process to ensure proper dimensional tolerances of both the nipple and sidepocket. Additionally, consider using a different type of nipple or sidepocket with a more secure design.
Cause 2: Material incompatibility: * Solution: Test different material combinations for the nipple and sidepocket to find the optimal pair that provides the best adhesion and friction. Consider using materials with higher strength and resilience.
Cause 3: Vibrations during assembly or product use: * Solution: Introduce vibration dampeners during assembly or product use. Consider using a different assembly technique that minimizes the impact of vibrations on the nipple and sidepocket connection.
