Child accommodating apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional armrests in child accommodating apparatuses are non-adjustable and inconvenient for holding infants/children, lacking a simple and reliable mechanism for easy operation and adjustment.
Innovation Solution
A child accommodating apparatus with an armrest rotating mechanism featuring a simple structure, including an engagement device and operation device, allows the armrest tube to be rotated and adjusted relative to the frame, utilizing a driving groove, inserting pin, and transmission member for easy disengagement and locking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional fixed or detachable armrest is used, then the structure is simple, but the armrest cannot be adjusted and is inconvenient for holding infants/children
Solution Approach 1:
The armrest is designed to be dynamically adjustable between multiple positions (lowered and lifted positions) rather than being fixed. The rotating mechanism allows the armrest to change its position dynamically, enabling caregivers to easily access and hold infants/children while maintaining a relatively simple overall structure through the use of a rotation joint and positioning mechanism.
2Ease of operation
If an armrest rotating mechanism is added to enable adjustment, then the armrest becomes adjustable and convenient for operation, but the structure becomes more complex
Solution Approach 1:
The armrest adjustment mechanism is segmented into distinct functional components: a rotation joint for position changing, an engagement device with positioning grooves for stable positioning, and a resilient member for providing restoring force. This segmentation allows each component to perform its specific function simply, avoiding the need for a complex integrated mechanism while achieving reliable adjustability.
Solution Approach 2:
The resilient member (spring) provides automatic restoring force to return the armrest to its original position after adjustment, eliminating the need for additional motors or complex control systems. The engagement device with positioning grooves provides automatic positioning when the armrest reaches specific angles, reducing the need for precise control mechanisms.
3Reliability
If a rotating mechanism with engagement device is used, then reliable locking is achieved, but the unlocking operation may become complicated
Solution Approach 1:
The engagement device acts as an intermediary between the armrest tube and the frame, using positioning grooves and engaging pins to provide reliable locking without requiring complex locking mechanisms. The resilient member serves as a mediator that provides the force needed to engage and disengage the positioning mechanism, making unlocking simple while maintaining reliability.

AI summary
A child accommodating apparatus is provided and includes a frame and an armrest tube. The armrest tube is rotatably connected with the frame. The armrest rotating mechanism is for rotating the armrest tube. The armrest rotating mechanism includes an engagement device and an operation device. The engagement device is disposed between the armrest tube and the frame and for positioning the armrest tube relative to the frame. The operation device is disposed on the armrest tube and connected with the engagement device. The operation device includes a housing coaxially and rotatably sleeved on the armrest tube and rotatable relative to the armrest tube. When the housing of the operation device is operated to rotate relative to the armrest tube, a rotating movement of the housing of the operation device drives the engagement device to disengage the armrest tube from the frame.
