Hose Connector Tool with Converging Passage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge lies in efficiently mating a braided hose with a connector/socket while minimizing exposure to the frayed ends of the hose sheath, which can cause discomfort and injury during assembly due to the disturbed sheath resulting from cutting.
Innovation Solution
A tool with a converging passage that constrains the size of the disturbed sheath, reducing its diameter to match the connector opening, allowing safe and secure insertion of the hose end into the connector/socket, featuring a body with a locator for the connector and a confining path that includes a frustum conical surface to align and reduce the sheath diameter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the hose is cut to length from bulk material, then the required hose length and connector configuration can be achieved, but the sheath becomes disturbed or frayed causing safety hazards and assembly difficulties
Solution Approach 1:
The patent introduces a guiding passage as an intermediary structure between the hose end and connector. This passage has walls that guide and contain the frayed sheath, preventing it from protruding outward to cause injury while still allowing the hose to be inserted into the connector. The guiding passage acts as a mediator that resolves the conflict between achieving custom hose lengths and preventing sheath fraying hazards.
2Ease of operation
If the frayed sheath is allowed to remain exposed during assembly, then the assembly process is simpler, but the user is exposed to cuts and discomfort
Solution Approach 1:
The guiding passage serves as a protective intermediary that allows the frayed sheath to remain in its natural state without requiring additional protective measures. The passage walls contain the frayed wires, enabling simple assembly operations while simultaneously protecting the user from injury. This resolves the contradiction by providing passive protection through the structural design of the passage rather than requiring active user precautions.
3Device complexity
If a traditional open-ended tool is used for hose assembly, then the tool structure is simpler, but the frayed sheath can protrude and cause injury
Solution Approach 1:
The tool is segmented into distinct functional zones: an opening for receiving the hose, a guiding passage with confining walls, and a connector receiving area. The guiding passage is further divided into sections with varying degrees of confinement. This segmentation allows the tool to provide protection against frayed sheath while maintaining relatively simple construction, resolving the contradiction between device complexity and safety.
4Object-affected harmful factors
If the hose sheath is constrained during insertion, then user safety is improved, but the hose insertion process becomes more complex
Solution Approach 1:
The guiding passage is formed with walls that create a flexible confining environment for the hose insertion. The passage structure provides constraint through its geometric configuration rather than through complex mechanical constraining mechanisms. The walls guide and contain the frayed sheath passively as the hose is inserted, improving safety without adding complex active constraining systems.
