Convertible Child Chair With Strap Storage and Detachable Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Child chairs lack detachability between the seat and supporting frame, leading to space inefficiency in storage, and the straps used for securing boosters can cause safety issues when not in use due to improper storage.
Innovation Solution
A child chair design featuring a detachable supporting frame and integrated strap storage system, where the seat includes a coupling section and storage for the straps, allowing the chair to function as both a high chair and a booster, with the straps being securely stored when not in use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the supporting frame is permanently attached to the seat, then the structural stability is improved, but the storage space efficiency deteriorates
Solution Approach 1:
The child chair is divided into separable components: the seat and the supporting frame. The supporting frame can be detached from the seat through coupling mechanisms, allowing the chair to be stored in a compact configuration when not in use, thereby improving storage space efficiency while maintaining structural stability during operation.
2Reliability
If straps are provided for securing the booster, then the safety function is improved, but the safety issue deteriorates when straps are not properly stored
Solution Approach 1:
The straps are extracted from the main body of the chair and provided with dedicated storage compartments. When not in use, the straps can be completely removed from the operational area and stored in designated spaces, eliminating the strangling hazard while preserving the safety function when needed.
Solution Approach 2:
Dedicated storage compartments act as intermediaries between the straps and the child's environment. These compartments provide a safe intermediate state for the straps when not in use, preventing direct contact between the loose straps and the child, thereby eliminating the strangling hazard.
3Ease of manufacture
If the chair is designed as a single fixed configuration, then the manufacturing simplicity is improved, but the adaptability deteriorates
Solution Approach 1:
The chair transitions from a static, fixed configuration to a dynamic, reconfigurable system. The coupling mechanisms between the seat and supporting frame allow the chair to adapt between different configurations (attached and detached states), providing versatility while maintaining relatively simple manufacturing processes for each component.

AI summary
When a supporting frame (20) is assembled to a seat (10, 10'), the child chair (1) is used as a high chair. When the supporting frame (20) is detached from the seat (10, 10'), the child chair (1) may be served as a booster. The seat (10, 10') includes storages (121) with straps (171, 172) connected. Each storage (121) is covered with a cover (151, 152, 161, 162) selectively configured between a closed position and an opened position. When the supporting frame (20) is detached from the seat (10, 10'), the covers (151, 152, 161, 162) may be moved to the opened position, covering coupling sections (14) of the seat (10, 10') so that the supporting frame (20) is not permitted to assemble to the seat (10, 10'); the straps (171 , 172) are reachable outward the storages (121) to secure the seat (10, 10') to an adult chair (2). When the straps (171, 172) are stored in the storages (121), the covers (1 51 , 1 52, 161, 162) may be moved to the closed position, covering the storages (121) and the coupling sections (14) are exposed. The supporting frame (20) is then permitted to assemble to the seat (10, 10').
