Threaded Plug with Multi-Profile Head for Universal Tool Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Industrial assembly lines face inefficiencies due to the need to constantly change tools when working with plugs featuring different threads, as existing threaded plugs require specific tools for each thread type, leading to slowed production.
Innovation Solution
A threaded plug design featuring two non-coincident profiles along its axis, allowing a single tool to be used for tightening by accommodating different tool shapes and sizes through distinct portions on the head, including cavities for screwdriver use, and a protective element with matching profiles for various head types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a threaded plug uses a single head profile for tightening, then the structure is simple and manufacturing is easy, but different thread types require different tools which slows down assembly lines
Solution Approach 1:
The head of the threaded plug is designed with multiple non-coincident profiles (first profile and second profile) that allow different tools to engage with the same head. This multi-functional design enables a single plug head to accommodate various tool types, eliminating the need to change tools when working with different thread types, thereby increasing assembly line productivity without requiring multiple specialized head designs
2Adaptability or versatility
If multiple tool interfaces are integrated into the plug head, then tool versatility improves and a single tool can tighten different plugs, but the manufacturing complexity increases
Solution Approach 1:
The head is segmented into distinct portions, each featuring a different profile (first profile and second profile). This segmentation allows each profile to be optimized for specific tool types while maintaining manufacturability through modular design. The profiles are positioned at different locations on the head, enabling tool versatility without requiring complex integration of multiple interfaces into a single monolithic structure
3Loss of time
If the plug head accommodates multiple profile types for different tools, then the need to change tools is eliminated, but the head design becomes more complex
Solution Approach 1:
Instead of adding complexity in the radial dimension with multiple interface types, the solution positions different profiles at different angular locations around the head's circumference. This spatial arrangement in the angular dimension allows multiple tool interfaces to coexist without interfering with each other, eliminating tool changing time while keeping the head design relatively simple through systematic spatial organization

AI summary
A threaded plug includes a structure which extends along an axis and includes a head, a body provided with an outer thread, and a clamping flange inserted between the head and the body; wherein the head includes, along the axis, at least one first portion having an outer lateral surface which features a first profile and at least one second portion having an outer lateral surface which features a second profile which is not coincident with the first profile.
