Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless communication is used to connect the portable electronic device and external input device, then operational convenience is improved, but wireless signal interference occurs in crowded environments
Solution Approach 1:
The patent introduces a physical transmission cable as an intermediary medium to replace wireless communication. The cable includes a first connector connecting to the portable electronic device and a second connector connecting to the external input device, establishing a stable wired connection that eliminates wireless interference issues while maintaining operational convenience.
Solution Approach 2:
The patent replaces the electromagnetic field-based wireless communication system with a mechanical physical connection system. By substituting radio waves with copper conductors and connectors, the system achieves more reliable signal transmission in crowded environments while preserving ease of operation.
2Reliability
If the transmission cable is rigidly fixed between the holder and cover, then electrical connection stability is improved, but cable damage occurs during rotation
Solution Approach 1:
The patent transforms the rigid fixed connection into a dynamic flexible connection. The transmission cable is allowed to flex and deform within the arc structure during rotation, accommodating the changing spatial relationship between holder and cover while maintaining electrical connection stability and preventing cable damage.
Solution Approach 2:
The patent employs a flexible cable design that can bend and deform within the arc structure. This flexible connection allows the cable to accommodate rotational movements between the holder and cover without experiencing excessive stress or damage, while maintaining stable electrical connection.
3Volume of moving object
If the cable length is short to maintain compact structure, then device compactness is improved, but cable tension and damage risk increase during rotation
Solution Approach 1:
The patent nests the transmission cable within the arc structure, allowing the cable to follow the curved path defined by the arc structure during rotation. This nesting arrangement enables the cable to accommodate rotational movements without excessive tension while maintaining a compact overall device structure.
Solution Approach 2:
The patent resolves the cable length conflict by utilizing the three-dimensional space within the arc structure. The cable is routed through the arc structure's curved path, effectively using the vertical and radial dimensions to accommodate cable movement during rotation, thereby maintaining both compactness and cable integrity.

AI summary
A protection device for rotatably supporting a portable electronic device includes a cover, a holder and a transmission cable. The holder has a first surface and a second surface opposite to each other. A sunken slot is formed on the first surface which supports the portable electronic device. A hole structure of the holder is connected to the sunken slot and formed between the first surface and the second surface, and an arc structure is disposed on the second surface to rotatably assemble with a rotary portion of the cover. A section of the transmission cable is connected to a first connector to be disposed inside the sunken slot, another section of cable is connected to a second connector to be embedded into the cover, and a middle section of the cable pierces through the hole structure to electrically connect the first connector with the second connector.
