Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a flexible arm with hot fusion assembly is used for the push button, then the push button can be assembled completely, but the assembling procedure becomes more complicated and takes more time
Solution Approach 1:
The push button structure is divided into separate functional components: a button body, a trigger mechanism, and a flexible arm. The flexible arm is further segmented into a mounting portion and a triggering portion. This segmentation allows each part to be assembled independently through simple snap-fit connections rather than requiring complex hot fusion assembly, thereby simplifying the overall assembling procedure while maintaining structural integrity
Solution Approach 2:
The triggering element and the flexible arm are merged into a single integrated component where the triggering portion of the flexible arm directly forms the trigger mechanism. This merging eliminates the need for separate assembly steps between the trigger and flexible arm, reducing assembling complexity while ensuring reliable force transmission from the button press to the switch
2Productivity
If a flexible arm with hot fusion assembly is used for the push button, then the push button can be assembled completely, but the assembly takes more time
Solution Approach 1:
The flexible arm is pre-formed with integrated mounting features and triggering elements during the molding process. The mounting portion includes pre-formed engagement structures that align with corresponding features in the housing, allowing for rapid snap-fit assembly without requiring time-consuming hot fusion operations. This preliminary preparation of components significantly reduces assembly time while maintaining assembly completeness
3Ease of manufacture
If a longer flexible arm is used for the push button, then the push button can be fully assembled, but the push button occupies a relatively larger space inside the housing
Solution Approach 1:
The flexible arm is designed to utilize the vertical dimension of the housing by extending downward from the button area through the penetrating hole to reach the switch element. This vertical orientation allows the flexible arm to achieve the necessary triggering length while occupying minimal horizontal space within the housing, effectively solving the space occupation problem while maintaining assembly completeness
Solution Approach 2:
The flexible arm incorporates dynamic elasticity to provide the necessary mechanical advantage for triggering the switch. The elastic portion of the flexible arm stores and releases mechanical energy during button pressing, allowing for effective trigger actuation with a shorter, more compact structure that occupies less space while still achieving complete assembly functionality
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 design reduces assembly complexity and enhances the stability of the push button structure, allowing for a more compact and portable wireless adapter with reliable operation.
Implementation Method 1
the elastic element is pressed to be deformed, and the elastic element presses against the switching element on the printed circuit board to trigger an electric signal. After the user releases the button area, the switching element is restored to an original position of the switching element by an elastic deformation of the elastic element.
Implementation Method 2
The pivoting shaft is rotatably inserted into the pivoting hole. The moving end has a triggering element. The triggering element is disposed corresponding to the switch unit of the adapter unit for triggering the switch unit.
Implementation Method 3
a retaining flange abuts against the housing inner surface to prevent detachment
