Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing child seat side impact protectors lack sufficient safety measures to prevent incorrect use or adjustment, leading to potential misuse or incorrect setting, which can compromise safety during vehicle accidents.
Innovation Solution
A child seat design featuring a side impact protector that can be transferred between a rest and functional position, with means to impede movement into the rest position, such as a position transfer device and hidden or concealed actuating devices, ensuring the side impact protector remains in the functional position without external influence, thereby enhancing safety by reducing the risk of incorrect adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the side impact protector is made easily transferable between rest and functional positions, then the ease of operation is improved, but the reliability is worsened due to risk of incorrect adjustment
Solution Approach 1:
The side impact protector is designed with dynamic characteristics, allowing easy transfer between rest and functional positions through spring-loaded mechanisms. The protector can be quickly deployed when needed while automatically returning to rest position, maintaining ease of operation throughout the product lifecycle.
Solution Approach 2:
The system performs preliminary action by automatically transferring the side impact protector to the functional position in anticipation of potential side impacts. The position transfer device is pre-configured to activate automatically, eliminating the need for manual intervention during critical moments and ensuring reliable protection.
2Ease of operation
If automatic position transfer is implemented, then the ease of operation is improved, but the reliability is worsened due to potential malfunction of automated device
Solution Approach 1:
The side impact protector system is designed to be self-serving through automatic position transfer mechanisms that require no external control or power source. The spring-loaded design and mechanical linkages enable the protector to automatically deploy and return to rest position based purely on physical principles, eliminating electronic components that could malfunction.
Solution Approach 2:
The system incorporates inherent mechanical constraints and guide structures that prevent incorrect positioning before the protector is activated. The rest and functional positions are mechanically defined with stops and engagement features that ensure proper alignment, cushioning against potential malfunctions through passive mechanical design.
3Reliability
If the side impact protector is locked in rest position, then the reliability is improved, but the ease of operation is worsened due to difficulty in activation
Solution Approach 1:
Spring elements are used to create a counterbalancing force that holds the side impact protector in the rest position during normal conditions. These springs provide sufficient holding force for stability while allowing easy displacement when a side impact occurs, as the impact force easily overcomes the spring resistance.
Solution Approach 2:
The locking mechanism transitions from a static locked state to a dynamic unlocked state automatically upon detecting side impact forces. The mechanical design allows the protector to be firmly held in rest position during normal use but becomes easily activatable when subjected to impact forces, maintaining both reliability and ease of operation.
4Reliability
If multiple locking mechanisms are added to prevent incorrect use, then the reliability is improved, but the device complexity is worsened
Solution Approach 1:
Multiple protective functions are merged into a unified mechanical system. The position transfer device, spring elements, and mechanical constraints work together as an integrated mechanism rather than separate components. This combination achieves reliable protection against misuse while avoiding the complexity of multiple independent locking systems.
Solution Approach 2:
The system uses self-regulating mechanical properties such as spring tension and geometric constraints to prevent incorrect use without requiring additional active locking mechanisms. The protector automatically maintains proper positioning through its inherent mechanical design, eliminating the need for complex external control systems.
