Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If multiple components (connecting frame, securing hook, tightening member, connecting tube, cover, sleeve, bolt) are used to ensure secure connection, then the connection strength is improved, but the device complexity and assembly difficulty increase
Solution Approach 1:
The patent combines multiple separate components (connecting frame, securing hook, tightening member) into a single integrated coupling member. This coupling member includes an outer threaded section for connecting to the connecting tube and an inner threaded section for securing the intake tube, eliminating the need for separate securing hooks and tightening members while maintaining secure connection strength
Solution Approach 2:
The coupling member serves multiple functions: it acts as both a connecting element (outer threaded section) and a tightening element (inner threaded section with screw member), replacing multiple specialized components with a single multi-functional part that performs both connection and securing operations
2Strength
If multiple components (connecting frame, securing hook, tightening member, cover, sleeve, bolt) are used to ensure secure connection, then the connection strength is improved, but the material costs increase
Solution Approach 1:
The patent merges six separate components into one coupling member, directly reducing the quantity of parts from 6 to 1. This consolidation maintains the structural integrity and connection strength while significantly reducing material consumption and manufacturing costs
Solution Approach 2:
The invention extracts and eliminates unnecessary intermediate components (securing hook, tightening member, separate cover, sleeve, bolt) from the assembly, keeping only the essential coupling member that performs all necessary functions, thereby reducing part quantity and material costs
3Reliability
If multiple components (sleeve, bolt, securing hook) are used to secure the assembly, then the reliability of connection is improved, but the ease of operation deteriorates
Solution Approach 1:
The patent combines the securing function (previously requiring sleeve and bolt) and the connecting function (previously requiring separate securing hook) into a single integrated coupling mechanism, reducing the assembly steps from multiple component installations to a single coupling member installation
Solution Approach 2:
The coupling member is segmented into functional sections (outer threaded section, inner threaded section, screw member) that can be independently manufactured but function as a unified component, allowing for easier manufacturing and assembly while maintaining connection reliability
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables quick and strong assembly with fewer parts, reducing manufacturing costs and enhancing sealing effectiveness.
Implementation Method 1
a screw member of the coupling member is screwed into a screw aperture, and the screw member moves towards a connecting aperture to tighten onto the intake tube
Implementation Method 2
An inner threaded section is then screwed onto an outer threaded section of the coupling member to firmly connect the intake tube, the coupling member and the connecting tube together
Implementation Method 3
a sealing sleeve is disposed adjacent to the sealing face, and the sealing face is placed in the securing section and pressed by the sealing sleeve against a first stopping face and a second stopping face
