Playard Bassinet Access Opening for Folding Without Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing playards require the bassinet to be removed for folding and height adjustment, leading to inconvenience and increased risk of loss during storage.
Innovation Solution
A foldable playard with a bassinet that features a folding device accessible through an opening in the bottom panel and a height adjustment mechanism using engaging components on the side panels, allowing the bassinet to remain mounted while changing between depth states and folding configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the bassinet is removed from the playard frame for folding or height adjustment, then the folding device can be accessed and the bassinet can be adjusted, but the operation becomes inconvenient and the bassinet is likely to be forgotten and difficult to store
Solution Approach 1:
The bassinet bottom panel is segmented with a removable cover portion that can be detached to expose the folding device, while the main bassinet structure remains attached to the playard frame. This segmentation allows access to the folding mechanism without requiring complete removal of the bassinet.
Solution Approach 2:
The cover acts as an intermediary element between the bassinet interior and the folding device. By removing only the cover rather than the entire bassinet, users can access and operate the folding device while the bassinet remains in place, serving as a mediator that enables the folding operation without complete detachment.
2Adaptability or versatility
If the bassinet is removed from the playard frame for height adjustment, then the height can be changed, but the bassinet requires separate storage and increases storage complexity
Solution Approach 1:
The bassinet is designed with dynamic adjustability through the cover removal mechanism, allowing it to transition between different operational states (adjusted height vs. normal position) while remaining physically attached to the playard frame. This dynamic design eliminates the need for separate storage locations for different height configurations.
Solution Approach 2:
The bassinet structure serves multiple functions: it provides infant containment, allows height adjustment, and maintains attachment to the playard frame simultaneously. The cover removal mechanism enables the bassinet to perform both its containment function and the folding/adjustment operation without requiring separate storage space.
3Productivity
If the bassinet remains mounted on the playard frame during folding, then storage efficiency improves, but the folding device becomes inaccessible
Solution Approach 1:
The bassinet is segmented into a main structure and a removable cover. This segmentation allows the cover to be detached for accessing the folding device while the main bassinet structure remains mounted on the playard frame, maintaining storage efficiency while enabling operation access.
Solution Approach 2:
Only the local portion of the bassinet (the cover) is removed to expose the folding device, rather than removing the entire bassinet. This local quality change allows selective access to the folding mechanism while maintaining the bassinet's mounted position and storage efficiency.

AI summary
The playard includes a frame body and a bassinet detachably mounted on the frame body. An opening and a cover that covers onto the opening are configured at the bottom panel of the bassinet. When the cover opens relative to the opening, a folding device at the bottom of the frame body can be operated by a user's hand sticking into the opening for folding the playard to a smaller size without the need of removing the bassinet. A height adjustment device is further configured on the side panels of the bassinet for adjusting the height of the bassinet by selectively setting the bassinet in a first using state that has a shallow depth or in a second using state that has a deep depth.
