Track Link Sensor Cavity Sealing With Flat Surrounding Protrusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing track links face challenges in properly sealing wear sensors due to surface features, leading to leakage and inadequate sealing of containment materials during curing, which affects the sensor's placement and functionality.
Innovation Solution
A track link design featuring a protrusion with a substantially flat surface surrounding the sensor cavity, providing an improved sealing surface and additional material for adequate depth to secure the sensor, along with a method of forming this design through forging and machining to ensure proper sealing during the setting of containment materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cavity is formed in the track link to receive the sensing device, then the sensor can be held and sealed in the track link, but the surface features of the track link make it difficult to properly seal the material while it sets, causing leakage
Solution Approach 1:
A protrusion is formed on the track link body before the cavity is created. This protrusion extends beyond the outer surface of the link body and surrounds the cavity, providing a pre-formed sealing surface that prevents leakage of containment material during the curing process. The protrusion is created as part of the initial forming process, ensuring the sealing feature is in place before material application.
Solution Approach 2:
The sealing function is separated from the main link body by creating a distinct protrusion feature. This protrusion acts as an independent sealing element that surrounds the cavity, allowing the containment material to be properly sealed against the protrusion's outer surface rather than relying on the irregular outer surface of the link body itself.
2Reliability
If containment material is applied to seal the sensor in the track link, then the sensor is held in place, but the material may leak from the track link before it sets and form an undesirable shape
Solution Approach 1:
The protrusion is formed in advance on the track link body, creating a defined sealing surface before the containment material is applied. This pre-formed structure guides the containment material into the proper shape as it sets, preventing leakage and ensuring the material forms the desired configuration around the sensing device.
Solution Approach 2:
The protrusion creates a localized sealing zone with a specific geometry that is optimized for containing the material. The outer surface of the protrusion provides a uniform sealing surface, while the cavity interior provides the necessary volume for the sensing device and containment material, creating different functional zones within the same structure.
3Reliability
If the track link includes surface features for sensor mounting, then the sensor can be secured, but these features make it difficult to properly seal the containment material
Solution Approach 1:
The protrusion is formed as part of the initial track link manufacturing process, creating the mounting and sealing features before final assembly. This ensures that the protrusion's outer surface provides a precise, uniform sealing surface that is integrated into the link body structure, eliminating the need for additional sealing operations.
