Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single-buckle locking structure is used with the button, then the device complexity is reduced, but the reliability deteriorates due to uneven stress causing the button to get stuck and not bounce back
Solution Approach 1:
The locking structure is segmented into two separate buckle arms (first buckle arm and second buckle arm) that independently engage with corresponding locking members. This segmentation distributes the stress from button operation across multiple independent pathways, preventing the single-point failure mode where uneven stress causes the button to stick. Each buckle arm can move and respond independently to stress variations.
2Reliability
If a locking structure with symmetrical buckle arms is implemented, then the reliability is improved by preventing button sticking, but the device complexity increases due to additional components and assembly steps
Solution Approach 1:
The two buckle arms are connected through a connecting member to form an integrated two-way buckle assembly. This merging approach allows the system to achieve the reliability benefits of dual independent locking pathways while consolidating the structure into a unified component that can be manufactured and assembled as a single unit, thereby reducing overall system complexity.
3Manufacturing precision
If conventional terminal contact design is used, then the manufacturing precision requirements are reduced, but the harmful factors increase due to higher contact resistance and heat generation
Solution Approach 1:
The contact cylinder incorporates dome structures that provide multi-point contact capability. This dimensional approach transforms a traditional single-point or linear contact interface into a distributed contact system where the dome geometry creates multiple contact zones simultaneously, reducing contact resistance and heat generation without requiring extremely tight manufacturing tolerances on individual contact points.
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 connector provides convenient operation with a long service life, reduces the risk of the button being stuck, and enhances safety by minimizing contact resistance and heat generation.
Implementation Method 1
a reset spring sleeved on the link and locking members installed on both sides of the bottom of the button brake block in respective; and lower ends of the locking members are provided with lean-against portions that are in contact with and leaning against the first buckle arm and the second buckle arm in respective
Implementation Method 2
the contact cylinder is arranged in a hollow and cylindrical manner, a plurality of first cutting holes are formed in the contact cylinder, and mounting sheets are arranged in the first cutting holes; one end that each mounting sheet is close to an opening of the conductive terminal is provided with a second cutting hole, and a dome is installed in the second cutting hole; and at least one reinforcing member for connecting the mounting sheets to the first cutting holes is also installed in the first cutting holes. When being plugged with the contact cylinder, the male terminal is in elastic contact with the dome first, and then in rigid contact with the mounting sheets, which is conducive to improving a positive force when the male terminal is plugged into the contact cylinder, thereby reducing a contact resistance.
