Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the foldable support uses a larger operable space design, then user operable space increases, but support performance deteriorates
Solution Approach 1:
The support structure is divided into multiple segments (first support plate and second support plate) that can rotate relative to each other. This segmentation allows the structure to expand the operable space while maintaining support performance through the rotational joints that preserve structural integrity.
Solution Approach 2:
The support plates are designed to be dynamic rather than static, allowing rotation between different angles. The magnetic members provide dynamic control over the relative positioning of support plates, enabling the structure to adapt between compact and expanded configurations while maintaining stability in each state.
2Area of moving object
If the foldable support structure is expanded to increase operable space, then user space increases, but structural stability deteriorates
Solution Approach 1:
Magnetic members are pre-installed on the support plates to automatically engage and lock the plates at predetermined angles. This preliminary magnetic positioning ensures structural stability is maintained when the operable space is expanded, as the magnetic force pre-establishes stable relative positions between support plates.
3Ease of operation
If magnetic members are used to control support plate angles, then ease of operation improves, but device complexity increases
Solution Approach 1:
Traditional mechanical locking mechanisms are replaced with magnetic members that use magnetic attraction and repulsion forces to control the angles between support plates. This substitution eliminates complex mechanical linkages, springs, and latches while improving ease of operation through automatic magnetic engagement and disengagement.

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 effectively increases the operable space for users while ensuring good support performance and stability, enhancing the overall user experience by allowing for various usage configurations.
Implementation Method 1
the first magnetic member is configured to attract the second magnetic member in a case that an included angle between the first support plate and the bottom plate is less than a preset angle
Implementation Method 2
the first magnetic member is further configured to repel the second magnetic member in a case that the included angle between the first support plate and the bottom plate is greater than or equal to the preset angle
Implementation Method 3
the rotary mechanism has a first conductive contact point; and the first conductive contact point is configured to conduct with the first magnetic member in a case that the included angle between the first support plate and the bottom plate is less than the preset angle, to enable magnetism of the first magnetic member to attract that of the second magnetic member
