Baby Carrier Head Protection Sheet With Synchronized Belt Sliding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing baby carriers often have protection sheets that misalign with the buckle or shoulder belt during use, exposing the buckle and causing discomfort or injury to the baby's head and neck due to friction or collision.
Innovation Solution
A head protection device with a protection sheet and limiting structure that slides relative to the shoulder belt, ensuring it remains aligned and secure, connected to a length adjustment device that synchronizes with the belt's movement to prevent exposure and friction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the protection sheet is installed only on the shoulder belt, then the structure is simple, but the protection sheet may misalign with the buckle during use, exposing the buckle and causing discomfort or injury to the baby
Solution Approach 1:
The protection sheet is divided into a first part and a second part, with the first part covering the buckle area and the second part covering the shoulder belt area. This segmentation allows each part to perform its specific function independently, ensuring the buckle remains covered while maintaining structural simplicity
Solution Approach 2:
A connecting structure is introduced as an intermediary element between the first part and second part of the protection sheet. This connecting structure maintains the relative position between the two parts, preventing misalignment and ensuring the buckle remains consistently covered during baby carrier use
2Adaptability or versatility
If the protection sheet is made adjustable to follow baby growth, then the adaptability improves, but the structure becomes more complex requiring additional adjustment mechanisms
Solution Approach 1:
The protection sheet incorporates a sliding mechanism that allows it to move dynamically along the shoulder belt as the baby grows. The first part can slide relative to the second part through the connecting structure, enabling continuous adjustment without complex discrete adjustment levels or additional mechanisms
Solution Approach 2:
The sliding mechanism allows the protection sheet to be easily adjusted by the user through simple manual operation. The design enables self-adjustment without requiring tools or complex procedures, making the adjustment process as simple as sliding the first part along the shoulder belt

AI summary
A head protection device for wrapping a shoulder belt and a length adjustment device of a carrier, the shoulder belt connected to a backrest and a seat of the carrier, and the shoulder belt wound around the length adjustment device, the length adjustment device slideable relative to the shoulder belt along a length extension direction of the shoulder belt. The head protection device includes a protection sheet, including a first part located between the length adjustment device and the backrest, and a limiting structure, arranged on the first part, wherein, the shoulder belt passes through the protection sheet twice in opposite directions at at least one position on the first part through the limiting structure, and the protection sheet is slidable relative to the shoulder belt along a length extension direction of the shoulder belt, the length adjustment device synchronously slides with the protection sheet on the shoulder belt.
