Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing safety seats with side protection blocks often fail to provide adequate side impact protection due to user negligence in unfolding or folding the blocks, leading to reduced functionality.
Innovation Solution
A side protection mechanism featuring a pivotal connection mount, side protection block, and motor that automatically unfolds and folds the block using a gear system, allowing for motor-driven or manual operation, with a locking mechanism to maintain the block's position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If side protection blocks are designed to be foldable to reduce storage space, then the volume of the safety seat is reduced, but the reliability of side impact protection is compromised due to user negligence in unfolding or folding the blocks
Solution Approach 1:
The system automatically detects collision conditions and triggers the side protection blocks to unfold without user intervention. The control unit monitors sensor data and autonomously activates the motor-driven mechanism, eliminating the need for users to manually operate the blocks and ensuring protection is always engaged when needed
Solution Approach 2:
The side protection blocks are pre-positioned in a folded state during storage, and the system prepares for potential deployment by continuously monitoring collision sensors. When a collision is detected, the blocks are rapidly deployed from their pre-positioned state, ensuring immediate protection without requiring user reaction time
2Reliability
If side protection blocks are made fixed to ensure consistent protection, then the reliability of side impact protection is improved, but the volume of the safety seat increases and portability is reduced
Solution Approach 1:
The side protection blocks transition from a static fixed design to a dynamic system that can change state between folded and unfolded positions. The motor-driven mechanism allows the blocks to adapt their configuration based on operational needs, providing consistent protection when deployed while maintaining a compact form during storage
Solution Approach 2:
The manual mechanical operation of folding and unfolding blocks is replaced with an automated motor-driven system. The motor receives electrical signals from the control unit and automatically positions the blocks, eliminating the need for user interaction while maintaining the ability to change between compact and protective states
3Device complexity
If manual operation of side protection blocks is used, then the device complexity is reduced, but the ease of operation is compromised when users forget to unfold or fold the blocks
Solution Approach 1:
The system incorporates sensors that continuously monitor collision conditions and provide feedback to the control unit. When a collision is detected, the feedback signal triggers the motor to automatically deploy the side protection blocks, ensuring the system responds appropriately to actual safety needs without relying on user memory or attention
Solution Approach 2:
The control unit acts as an intermediary between the collision sensors and the motor-driven mechanism. It processes sensor data and automatically activates the appropriate response, eliminating the need for direct user interaction with the blocks while ensuring protection is deployed based on actual collision conditions

AI summary
A side protection mechanism (16) for safety seat (1) includes a pivotal connection mount (162), a side protection block (164) pivotally connected to the pivotal connection mount (162), and a motor (166) disposed in the pivotal connection mount (162). The motor (166) is connected to the side protection block (164) to drive the side protection block (164) to rotate relative to the pivotal connection mount (162) to fold or unfold. A safety seat (1) includes a seat body (14) and the side protection mechanism (16) on a side of seat body (14). After the side protection block (164) rotates to unfold, the side protection block (164) protrudes from the seat body (14) and a locking block (1644) of the side protection block (164) is located outside and directly in front of a locking slot (162a) of the connection mount (162).
