Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rigid mounting structure is used to securely fasten the portable electronic device, then the reliability of mounting is improved, but the adaptability to different device sizes and shapes deteriorates
Solution Approach 1:
The patent employs an elastic protection sheath made of flexible material that can stretch and conform to different portable electronic device sizes and shapes. The sheath includes elastic strips that provide flexibility while maintaining secure fastening, allowing the same mounting structure to adapt to various devices without compromising reliability.
Solution Approach 2:
The elastic protection sheath changes its physical parameters (shape, size, stiffness) in response to the device it accommodates. By stretching and deforming elastically, the sheath adjusts its dimensions to match different device sizes while maintaining sufficient tension for secure mounting on the bicycle or motorcycle.
2Ease of operation
If a complex fastening mechanism is used to provide adjustable mounting positions and angles, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The connecting accessory incorporates a rotatable bracket that allows dynamic adjustment of the portable electronic device's mounting angle and position. This single rotating component provides multiple adjustable positions without requiring multiple separate mounting brackets or complex fastening mechanisms, thereby maintaining ease of operation while limiting overall device complexity.
3Object-affected harmful factors
If corner protection elements are added to protect the portable electronic device, then the protection level is improved, but the device complexity increases
Solution Approach 1:
The corner protection nets are integrated directly into the elastic protection sheath structure, forming a unified protective covering. The corner protection nets are connected to the sheath through the elastic strips, creating a combined structure that provides both protection and flexibility without requiring separate mounting hardware or complex assembly, thus improving protection while minimizing added complexity.
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 device provides a secure, adjustable, and convenient mounting solution for portable electronic devices, accommodating different sizes and allowing for easy operation by stretching the sheath and using the strap and connecting accessory to wrap around carriers, ensuring firm fixation and adjustable viewing positions.
Implementation Method 1
an elastic protection sheath, a connecting accessory and a strap; the elastic protection sheath being stretchable to increase accommodation size
Implementation Method 2
the corner protection nets buckling on the four corners of the portable electronic device with a tightness maintained by the elastic strips
Implementation Method 3
the strap being elastic and stretchable, and having a limiting hole and a plurality of buckle holes, the strap being sheathed on the position element by the limiting hole and the protruding hook being inserted into one of the buckle holes, the bracket and the strap being used to wrap and tighten around a carrier to be fastened to
