Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional assembly methods are used for control devices, then assembly precision can be maintained, but assembly time and complexity increase significantly
Solution Approach 1:
The stopping portions are pre-formed on the head and body components before assembly. During assembly, these pre-formed stopping portions automatically engage with each other through mutual limitation, eliminating the need for complex real-time alignment and adjustment operations, thus reducing assembly time while maintaining precision
Solution Approach 2:
The stopping portions are designed to automatically limit and constrain each other through their geometric shapes during assembly. The components self-align and self-constrain without requiring external fixtures or complex positioning mechanisms, simplifying the assembly process while ensuring precise positioning
2Stability of the object's composition
If traditional assembly methods are used for control devices, then connection stability can be achieved, but assembly complexity increases
Solution Approach 1:
The connection mechanism is segmented into distinct stopping portions on separate components (head and body). Each stopping portion is independently formed with specific geometric features that complement each other, creating a stable connection through simple mutual limitation rather than complex integrated structures
Solution Approach 2:
Instead of using complex locking mechanisms or fasteners to achieve stability, the invention inverts the approach by using simple protruding stopping portions that limit each other's movement. The stability is achieved through the geometric constraint of these simple features rather than complex mechanical connections
3Productivity
If quick assembly is implemented, then assembly time is reduced, but assembly precision and stability may be compromised
Solution Approach 1:
The stopping portions are pre-formed with precise geometric dimensions and shapes during component manufacturing. This preliminary precision ensures that when the components are quickly assembled, the pre-formed features automatically align and constrain each other correctly, maintaining assembly precision despite reduced assembly time
Solution Approach 2:
The invention replaces complex mechanical positioning and alignment systems with simple geometric stopping portions that automatically constrain each other through their shapes. This substitution enables quick assembly without sacrificing precision, as the geometric features inherently guide and limit component positions

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables rapid and stable assembly of control devices with reduced assembly time and improved stability, accommodating various materials and manufacturing methods, while allowing for flexible engagement mechanisms.
Implementation Method 1
The stopping portion is pressurized by a mold to form the stopping portion deformed inward on another mold
Implementation Method 2
the elastic stopping portion protruding inward is abutted against the corresponding stopping portion of the body provided on another mold, so as to elastically engage and assemble the pressed and expanded stopping portion with the corresponding stopping portion protruding outward

AI summary
An assembly method and a structure of a control device are introduced. The control device includes a head and a body. The head includes a stopping portion, and the body includes a corresponding stopping portion. The head is movably assembled with the body upon pressurizing the head or the body by an external force. Thus, the head and the body can be quickly assembled into a control device, while achieving effects of easy assembly and better stability after the assembly.
