Oscillating Spray Tip Guard for Wear Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Oscillating spray tips used in 'potholing' operations wear down quickly due to repeated impact on hard surfaces and rock, leading to high costs as they need to be replaced frequently.
Innovation Solution
A tip protection assembly comprising a durable tip guard and lock plate that securely encases the oscillating spray tip, preventing unwanted disassembly and exposure, with a cavity design that allows unobstructed high-pressure water flow and uses materials like stainless steel or carbon fiber composite for enhanced durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If oscillating spray tips are used in potholing operations, then the ability to penetrate ground and detect utilities is achieved, but the spray tips wear down quickly due to repeated impact on hard surfaces and rock
Solution Approach 1:
A protective assembly comprising a tip guard and lock plate is introduced as an intermediary structure between the oscillating spray tip and the harsh environment. The tip guard encases the spray tip, and the lock plate secures it in place, creating a protective barrier that shields the brass spray tip from direct contact with hard surfaces and rock during potholing operations, thereby preventing wear and extending service life
2Ease of operation
If the spray tip is exposed and unprotected, then easy access and operation are maintained, but the spray tip is vulnerable to wear and tear from ground penetration
Solution Approach 1:
The protective assembly is divided into separate functional components: a tip guard that provides the primary protective enclosure and a lock plate that secures the assembly to the spray tip. This segmentation allows the protective function to be added without fundamentally redesigning the spray tip itself, maintaining operational simplicity while providing comprehensive protection against impact and wear

AI summary
The oscillating pressurized spray tip protection assembly is comprised of a tip guard and a lock plate that lock together via securing means over an oscillating spray tip in order to protect against wear when said spray tip is penetrating ground. The spray tip protection assembly utilizes a material that is strong, and more durable than the spray tip enclosed therein such that the life of the spray tip is increased. The tip guard has a cavity contoured to an exterior surface of the oscillating spray tip with an opening at a front end of the tip guard thereby enabling pressurized water to exit from both the oscillating spray tip as well as the tip guard.
