Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional screws are used as the axis for temple rotation, then the structure is simple, but there is no damping effect during rotation causing temples to shake and poor user experience
Solution Approach 1:
The patent introduces a positioning bead assembly as an intermediary component between the rotating shaft and the temple. The positioning bead, mounted on a movable connecting portion, interacts with the rotating shaft to provide damping during temple rotation without requiring complex shaft components. This mediator enables the damping effect while keeping the overall structure relatively simple.
2Reliability
If numerous and complex shaft components are used to achieve damping effect, then the damping effect is achieved, but the requirements for processing accuracy and assembly accuracy are high resulting in high product development costs
Solution Approach 1:
The patent replaces complex, high-precision shaft components with a simpler positioning bead assembly that has lower manufacturing and assembly precision requirements. The positioning bead, spring, and movable connecting portion form a durable yet simple mechanism that achieves the damping effect without requiring expensive, high-precision components.
Solution Approach 2:
The patent changes the approach from using precision-engineered shaft components to using a positioning bead assembly where the damping effect is achieved through the interaction between the bead, spring, and movable connecting portion. This parameter change in the mechanism type reduces the requirements for processing and assembly accuracy.
3Reliability
If complex shaft components are used to achieve damping, then the damping effect is achieved, but the product development costs are high
Solution Approach 1:
The patent uses a positioning bead assembly with simpler components (bead, spring, movable connecting portion) instead of complex shaft components, thereby reducing product development costs while maintaining the damping effect.
Solution Approach 2:
The patent extracts the damping function from the complex shaft components and implements it separately through the positioning bead assembly. This separation allows for simpler, lower-cost components to achieve the same damping effect.
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 device achieves effective rotational damping of the temples, enhancing user experience with a stable and smooth rotation effect, while maintaining a low-cost and simplified manufacturing process.
Implementation Method 1
the positioning bead assembly includes a housing, a spring contained in the housing, and a bead installed at the end of the spring and partially extending out of the housing
Implementation Method 2
There is no damping effect during the rotation of the temples, and the temples tend to shake, resulting in a poor user experience
