Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sliding-lid designs for handheld electronic devices often have a large overlapping area due to complex mechanisms combining sliding and pivoting functions, which restricts the utilizable space and increases manufacturing costs.
Innovation Solution
A pivot mechanism with a smaller volume and simpler design, utilizing a sliding module and rotating modules with elastic members and link rods to achieve semi-automatic rotation, reducing the overlapping area between device bodies and allowing for efficient manual and automatic manipulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mechanism combining sliding and pivoting functions is incorporated into the sliding-lid design, then the upper and lower bodies are coupled to realize manual manipulations such as sliding and rotating, but the volume of the mechanism increases and a larger overlapping area exists between the upper and lower bodies
Solution Approach 1:
The patent divides the mechanism into separate sliding module and rotating module, which can independently function or combine. This segmentation allows the mechanism to achieve both sliding and rotating manipulations while reducing the overall volume compared to a fully integrated complex mechanism, as each module can be optimized separately and only engages when needed.
2Adaptability or versatility
If a mechanism combining sliding and pivoting functions is incorporated into the sliding-lid design, then the upper and lower bodies are coupled to realize manual manipulations such as sliding and rotating, but the position and size of the keyboard, the screen or other elements are restricted
Solution Approach 1:
The patent employs dynamic positioning where the keyboard and screen elements can adjust their positions based on the manipulation state. The elements are not fixed but can move dynamically to accommodate different manipulation modes (sliding, rotating, or both), providing freedom in positioning while maintaining ease of operation.
3Adaptability or versatility
If an over-complicated mechanism design is used, then the sliding and pivoting functions are achieved, but the reliability and yield rate of the handheld electronic devices are affected and the manufacturing cost increases
Solution Approach 1:
The patent segments the mechanism into independent sliding module and rotating module, each with its own drive mechanism. This segmentation simplifies the overall design by allowing each module to be optimized independently with fewer components, reducing mechanism complexity while maintaining the ability to provide both sliding and rotating manipulations.
Solution Approach 2:
The patent designs the mechanism with universal components that can serve multiple functions. The same basic structural elements are used for both sliding and rotating operations, reducing the total number of unique components needed and simplifying the overall mechanism design while achieving manipulation diversity.
4Stability of the object's composition
If the sliding mechanism is arranged between the upper and lower bodies, then the bodies are connected to prevent detachment, but the upper and lower bodies partially overlap and part of the utilizable area of the lower body is covered
Solution Approach 1:
The patent transitions the sliding mechanism from a planar arrangement to a three-dimensional configuration. The sliding module moves along the thickness direction of the device bodies rather than parallel to the surface, allowing the upper and lower bodies to overlap minimally while maintaining stable connection. This dimensional change maximizes the utilizable surface area of both bodies.

Function Achieved in This Case
The solution provides a compact, reliable, and cost-effective mechanism that allows for semi-automatic rotation, enhancing user convenience while minimizing the overlapping area and manufacturing costs.
Implementation Method 1
the rotating module is suitable for receiving a force in order to store a potential. When the second body passes the critical position, the rotating module is suitable for releasing the potential to drive the second body to rotate

AI summary
A handheld electronic device, including a first body, a second body, a sliding module and at least one rotating module. The sliding module is coupled to the second body, so that the second body is suitable for sliding between a first position and a second position. The rotating module is coupled between the first body and the sliding module, so that the second body is suitable for rotating relative to the first body. The second body receives a force to rotate from the second position to a critical position. When the second body passes the critical position, the rotating module releases a potential stored when the second body receives the force to drive the second body to rotate to a third position and form an included angle between the first body and the second body. A sliding mechanism assembly is also disclosed.
