Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a side impact protection device mechanism is installed on side wings of a backrest, then side impact protection function is achieved, but the structure becomes complicated and operation becomes inconvenient
Solution Approach 1:
The patent extracts the side impact protection block from a complex mechanism and implements it as a simple pivotal component that can be rotated between extended and retracted positions. This single pivotal component replaces what would otherwise require complex mechanical assemblies, achieving the protection function while minimizing structural complexity
Solution Approach 2:
The locking structure is designed to automatically lock the side impact protection block in both extended and retracted positions without requiring manual intervention or complex control systems. The elastic cantilever automatically engages with the locking structure through elastic deformation, making the system self-servicing and eliminating the need for additional actuators or control mechanisms
2Reliability
If a side impact protection device mechanism is installed on side wings of a backrest, then side impact protection function is achieved, but operation becomes inconvenient
Solution Approach 1:
The patent simplifies the operation by extracting the essential function to a single pivotal movement action. Users only need to rotate the side impact protection block to extend or retract it, eliminating the need to operate complex mechanisms, levers, or multiple components, thereby greatly improving operational convenience
Solution Approach 2:
The automatic locking mechanism serves itself by using the elastic deformation of the cantilever to automatically engage the locking structure in both extended and retracted positions. This self-locking feature eliminates the need for users to manually secure the protection block, making operation as simple as rotating the component while ensuring reliable positioning
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 solution provides a simple and reliable side impact protection mechanism that is easy to operate, ensuring the side impact protection block is securely locked in both extended and retracted positions, enhancing user safety and convenience.
Implementation Method 1
an elastic cantilever is further provided on the axial end face of the pivotal assembling end at which the locking structure is located or on the groove side wall of the accommodating groove, the locking structure is located on the elastic cantilever, and during a process that the side impact protection block is switched between the extended position and the retracted position, the locking structure is unlocked from or locked with the cooperative locking structure by an elastic deformation of the elastic cantilever

AI summary
A child safety seat and a side impact protection device. The side impact protection device comprises a fixed seat assembled on the backrest and a side impact protection block pivotally coupled to the fixed seat via a pivot shaft. The side impact protection block has at least an extended position and a retracted position during a pivoting process around an axis of the pivot shaft in respect to the fixed seat, one of the fixed seat and the side impact protection block has a locking structure, and the other one of the fixed seat and the side impact protection block has a cooperative locking structure being cooperating with the locking structure, the locking structure is automatically locked with the cooperative locking structure when the side impact protection block is pivoted to the extended position around the axis. The side impact protection device is simple in structure and easy in operation.
