Child Safety Harness Actuator with Visual Locking State Indicator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing child safety seat harness systems often fail to ensure correct tensioning, leading to either discomfort or increased risk during crashes due to improper adjustment, and lack visibility into the locking mechanism's status, making it difficult for users to confirm correct securing of the child.
Innovation Solution
A harness system with a retractor device, locking mechanism, and release mechanism that allows for adjustable tensioning and loosening, featuring an actuator that visibly indicates its state, ensuring the harness remains secure and tight during accidents while allowing easy adjustment for comfortable seating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the harness system allows free adjustment of tension, then ease of operation is improved, but reliability deteriorates due to inability to confirm correct securing
Solution Approach 1:
The patent employs color-coded indicators (red/green or similar visual differentiation) on the actuator to communicate the locking mechanism state to users. This allows parents to quickly verify correct harness securing without complex procedures, resolving the contradiction by maintaining ease of operation while improving reliability through visual confirmation.
Solution Approach 2:
The patent implements a visual feedback system where the actuator's position or color changes to indicate whether the locking mechanism is engaged or disengaged. This feedback loop allows users to confirm correct harness tensioning and securing, addressing the reliability concern while preserving ease of adjustment.
2Reliability
If the locking mechanism prevents adjustment after engagement, then reliability is improved, but ease of operation deteriorates due to inability to correct incorrect tensioning
Solution Approach 1:
The patent creates a dynamic system where the locking mechanism's engagement state is visually indicated but not permanently fixed. The actuator can be deliberately actuated to switch between locked and unlocked states, allowing the system to transition between security and adjustability modes based on user intent, thus resolving the contradiction between reliability and ease of operation.
Solution Approach 2:
The actuator serves as an intermediary element between the user and the locking mechanism. By providing a clear visual indicator of the locking state, it allows users to make informed decisions about whether to engage or disengage the locking mechanism, enabling correction of incorrect tensioning while maintaining security when properly configured.
3Device complexity
If the buckle assembly hides the locking mechanism state, then device complexity is reduced, but measurement precision deteriorates due to inability to detect locking status
Solution Approach 1:
The patent uses color-coded visual indicators on the actuator (such as red for unlocked, green for locked) to communicate the locking mechanism state. This simple visual coding system provides precise status detection without adding mechanical complexity to the buckle assembly, resolving the contradiction between device complexity and measurement precision.
Solution Approach 2:
The patent creates a visual copy or representation of the internal locking mechanism state through the actuator's external appearance or position. This allows users to detect the locking status without exposing the actual mechanical locking components, maintaining structural simplicity while providing accurate status information.

AI summary
An automatic harness system (1) for a child safety seat comprising one tensioning web (3); a retractor device (2) configured to allow tightening of the tensioning web (3), a locking mechanism, a release mechanism is connected to the retractor device (2). The release mechanism comprises an actuator, where a movement of the actuator from a first position to a second position alternates the release mechanism from the first state to the second state, and vice versa. The actuator's position allows a user to identify whether the release mechanism is in the first state or in the second state.
