Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple adjusting apparatuses with shafts and dragging cables are used for three-axial rotation, then the projector can perform multi-directional rotation around each axis, but the structure becomes complex and operation becomes unstable
Solution Approach 1:
The patent combines multiple adjusting apparatuses into a single integrated structure where the first and second adjusting apparatuses share a common base and pivot shaft. The drag cables are merged into a coordinated system where one cable controls both adjusting apparatuses, reducing the number of independent components while maintaining multi-directional rotation capability.
Solution Approach 2:
The common base serves multiple functions by supporting both the first and second adjusting apparatuses. The pivot shaft enables rotation around multiple axes simultaneously. The drag cable system is designed to control both adjusting apparatuses through a single cable, making the system more versatile with fewer components.
2Adaptability or versatility
If multiple adjusting apparatuses with threaded sleeves and drag cables are assembled, then two-directional rotation around each axis is achieved, but the number of parts increases and manufacturing cost increases
Solution Approach 1:
The patent merges the structural components of multiple adjusting apparatuses into a unified design. The common base and shared pivot shaft eliminate redundant parts. The threaded sleeves are integrated into a coordinated system where fewer independent components are needed, reducing manufacturing complexity and cost.
3Ease of operation
If three adjusting apparatuses are used for three-axial rotation, then comprehensive angle adjustment is achieved, but the apparatus requires many parts causing unstable operation
Solution Approach 1:
By merging multiple adjusting apparatuses into a coordinated system with shared components, the patent reduces the total number of parts that could potentially fail. The integrated design ensures stable operation while maintaining comprehensive angle adjustment capability through the coordinated action of fewer, more reliable components.
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 apparatus enables stable, two-directional rotation of projectors around multiple axes with reduced malfunction risk and manufacturing costs, ensuring reliable operation and ease of assembly.
Implementation Method 1
The first adjusting rod has a first thread, and the first adjusting base has a first threaded hole. The first thread is engaged with the first threaded hole. When the first adjusting rod is rotated, no relative replacement exists between the first adjusting rod and the first base.

AI summary
An adjusting apparatus including first and second bases, a pivot shaft, an adjusting unit and a first cable is provided. The second base is disposed under the first base. The first and second bases are pivoted by the pivot shaft. The adjusting unit includes a first adjusting base and a first adjusting rod. The first adjusting rod is passed through the first base and the first adjusting base. The first cable has first and second sections, wherein the first and second sections have first end portions, the first end portions are fixed to the second base, and the first and second sections are held by the first adjusting base. When the first adjusting rod is rotated, the first adjusting base is moved relative first base, such that the first or second section is dragged and the second base is rotated around a first axis relative to the first base.
