Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the supporting plate is pivotally connected to the base plate with a simple structure, then the device complexity is reduced, but the holder becomes prone to sliding away during shaking, resulting in poor fixation and reduced reliability
Solution Approach 1:
The supporting portion is divided into three separate supporting plates (first, second, and third supporting plates) that are independently pivotally connected to the base plate. Each supporting plate can rotate independently around its own pivot axis, creating a segmented structure that distributes the supporting function across multiple independent elements rather than relying on a single complex plate
Solution Approach 2:
The patent introduces rotational degrees of freedom by allowing each supporting plate to rotate around pivot axes that extend in different directions (first rotation axis, second rotation axis, third rotation axis). This dimensional approach transforms the static supporting structure into a dynamic multi-axis rotational system, enabling the plates to adjust their positions independently to maintain stability during shaking while keeping each individual plate's structure simple
2Reliability
If the holder uses a complex structural design to improve stability, then the reliability is improved, but the holder becomes larger and bulkier, making it inconvenient for handheld use and portable storage
Solution Approach 1:
The holder is segmented into a base plate and multiple independent supporting plates that can be positioned in different configurations. When not in use, the supporting plates can be rotated to lie flat against the base plate, creating a compact profile suitable for portable storage. During use, the plates are rotated to their supporting positions, providing stability without requiring a permanently expanded structure
Solution Approach 2:
The supporting plates are designed to be dynamically positionable through rotation around pivot axes, transforming the holder from a static structure to a dynamic one. This allows the holder to adapt its configuration between a compact storage state (plates flat against base) and a stable supporting state (plates extended), eliminating the need for a permanently large structure to accommodate both functions
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 improves stability, reduces size, and facilitates convenient storage and use by providing both grip and supporting forces, while the magnetic attraction enhances device fixation and the foldable structure optimizes space usage.
Implementation Method 1
a magnetic attraction member (45) is arranged on the inner wall of the accommodating groove; the magnetic attraction member is used for attracting the electronic device
