Bedding covers and bedding cover systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional duvet covers are difficult to use, leading to inadequate cleaning frequency due to awkward insertion and removal of insulated bedding items, resulting in unhygienic conditions.
Innovation Solution
The proposed bedding cover system includes a cover member, a flap member, and a cover fastener, designed to securely cover insulated bedding items, facilitating easy installation, removal, and cleaning by defining a flap to receive and secure the item with interference fit fasteners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional duvet covers are used, then cleaning is easier compared to insulated bedding items, but insertion and removal of insulated bedding items becomes awkward and difficult
Solution Approach 1:
The bedding cover is divided into a cover member and a separate flap member that can be independently manipulated. The flap member acts as a separate segment that facilitates insertion and removal of the insulated bedding item, while the cover member provides the cleaning-friendly cover structure.
Solution Approach 2:
The flap member serves as an intermediary element between the user and the insulated bedding item during insertion and removal operations. By providing this intermediate component with fingers or tabs, the system mediates the difficult interaction of maneuvering bulk insulated items, making the operation easier without compromising the cleaning ease of the main cover.
2Productivity
If conventional duvet covers are used, then cleaning frequency increases, but the process becomes too difficult to maintain regular cleaning
Solution Approach 1:
The flap member is designed to be dynamic and flexible, allowing it to move and adapt during the insertion and removal processes. This dynamic characteristic enables the flap to facilitate easier handling of the insulated bedding item, making regular cleaning more feasible and increasing cleaning frequency.
Solution Approach 2:
The flap member changes the operational parameters of the bedding cover system by introducing additional degrees of freedom in manipulation. By altering how the cover interacts with the insulated item through the flap's movement and configuration, the system improves ease of operation, enabling more frequent cleaning cycles.
3Area of stationary object
If the cover member is made wide enough to cover the insulated bedding item, then coverage is adequate, but the flap becomes difficult to maneuver
Solution Approach 1:
By segmenting the cover into a wide cover member and a separate, narrower flap member, the design achieves full coverage width while keeping the manipulative flap portion narrow and easy to maneuver. The segmentation allows each component to be optimized for its specific function.
Solution Approach 2:
The flap member is designed with local quality differences - it has a narrower width at the manipulative end compared to the full cover width, making it easier to maneuver. The fingers or tabs on the flap are specifically designed with appropriate dimensions for easy gripping and manipulation, while the overall cover maintains adequate coverage area.

AI summary
Bedding covers for selectively covering an insulated bedding item. The bedding covers include a cover member, a flap member, and a cover fastener. The cover member is complementarily configured with the length and the width of the insulated bedding item. The cover member has a cover top edge having a cover width at least as wide as the width of the insulated bedding item. The flap member is coupled to the cover member along the cover top edge. The cover fastener is configured to secure the cover member to the insulated bedding item and is disposed on either the cover member or the flap member. The cover member and the flap member collectively define a flap configured to receive a portion of the insulated bedding item. The cover fastener and the flap cooperate to secure the insulated bedding item within the flap.
