Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional locking mechanism is used, then the backrest can be securely attached to the base, but the structure becomes complicated and operation becomes difficult
Solution Approach 1:
The locking mechanism is divided into separate functional components: a locking pin on the backrest, a locking component with locking hole structure on the base, and an operating component. These segmented parts work together to provide secure attachment while simplifying the overall structure and making each component's function clear and manageable.
Solution Approach 2:
The locking function is extracted from a complex integrated mechanism and implemented through a simple pin-and-hole engagement system. The locking pin and locking hole structure are separated from other backrest-base connection elements, allowing for independent optimization of the locking function while reducing overall structural complexity.
2Reliability
If a conventional locking mechanism is used, then the backrest can be securely attached to the base, but the attachment and detachment process becomes time-consuming and not user-friendly
Solution Approach 1:
The operating component merges multiple functions into a single element: it simultaneously controls the locking pin's engagement with the locking hole structure, operates the retractable locking component, and provides a user-friendly interface. This merging allows secure attachment while enabling easy one-handed operation for both attachment and detachment.
Solution Approach 2:
The locking pin is pre-positioned on the backrest and the locking hole structure is pre-formed on the base, so that when the backrest is brought toward the base, the locking components are already in place to engage. This preliminary positioning eliminates the need for complex alignment procedures during attachment, making the process quick and user-friendly.
3Ease of operation
If the locking mechanism is simplified, then operation becomes easier, but the compactness and reliability of attachment may be compromised
Solution Approach 1:
The locking pin is nested within or alongside the operating component, and the locking component with its retractable feature is nested within the base structure. This nesting arrangement maintains compactness while preserving the multi-component reliability of the locking system, allowing simple operation without compromising attachment security.
Solution Approach 2:
The locking mechanism incorporates self-locking features where the locking pin automatically engages with the locking hole structure when the backrest is attached to the base, and the retractable locking component self-adjusts during the attachment process. This self-service capability ensures reliable attachment while keeping the operating component simple and easy to use.
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 mechanism simplifies the attachment and detachment process while ensuring reliable connection, making it easier and more convenient for users to assemble and disassemble the backrest and base.
Implementation Method 1
the recovering component is resiliently deformed when the operating component is operated, and the resiliently deformed recovering component drives the operating component to recover

AI summary
A backrest locking mechanism adapted for a backrest and a base of a child safety seat is provided. The backrest is detachably connected to the base. The backrest locking mechanism includes a locking pin, a locking component and an operating component. The locking pin is disposed on the backrest. The locking component is disposed on the base. A locking hole structure is formed on the locking component. The locking pin is configured to detachably engage with the locking hole structure. The operating component is movably disposed on the backrest or the base. The operating component drives the locking pin and the locking hole structure to engage with or disengage from each other when the operating component is operated. Furthermore, a child safety seat having the aforementioned backrest locking mechanism is also provided.
