Elastic Pad Cover Structure for Removable Cleaning and Compact Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elastic pads for furniture, such as beddings and sofa beds, exhibit poor comfort, high cost, instability, and are inconvenient to clean and transport due to their integral design and large storage requirements.
Innovation Solution
A cover system for elastic pads featuring a removable outer wrapping cover with stop hems that form an inner space to receive and shield the elastic layers, allowing for improved assembly convenience, cleaning, and reduced storage space, along with an edge connection structure that eliminates enclosed side coverings for enhanced breathability and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the elastic pad uses an integral, non-detachable encapsulated design, then the structural stability is improved, but the ease of cleaning and transportation deteriorates
Solution Approach 1:
The elastic pad is divided into separable components: an inner core layer assembly (bottom layer, spring layer, sponge overlay) and an outer wrapping cover. The outer wrapping cover can be removed from the inner core layer assembly, allowing the cover to be cleaned separately while the core structure remains stable during use.
2Stability of the object's composition
If the elastic pad uses an integral encapsulated design, then the structural stability is improved, but the ease of operation deteriorates
Solution Approach 1:
The elastic pad structure is segmented into removable components. The outer wrapping cover can be detached from the inner core layer assembly, enabling the core structure to be folded or compressed for compact storage and transportation, while maintaining structural integrity during assembly and use.
3Stability of the object's composition
If the elastic pad uses enclosed side coverings, then the structural completeness is improved, but the device complexity increases
Solution Approach 1:
The enclosed side coverings are extracted and replaced with stop hems that extend downward from the outer wrapping cover to form an inner space. This eliminates the need for separate side covering components, reducing structural complexity while maintaining the enclosing function through the stop hems' downward extension.
4Stability of the object's composition
If the outer wrapping cover is permanently attached, then the structural stability is improved, but the ease of cleaning deteriorates
Solution Approach 1:
The connection between the outer wrapping cover and the inner core layer assembly is made dynamic rather than fixed. The cover can be removed and reattached, allowing it to be detached for cleaning purposes and then resecured to maintain structural stability during use. The stop hems provide the dynamic connection mechanism.

AI summary
The present disclosure which relates to the field of elastic pads for manufacturing household items discloses a cover (22), an elastic pad (2) and a furniture. The cover (22) comprises: at least one inner core layer (221) comprising an elastic material layer; an outer wrapping cover (222) removably wrapping the at least one inner core layer (221); and stop hems (23) folded downwards from peripheral edges of the cover (22) along a thickness direction of the elastic pad (2) and extending a predetermined distance, thereby forming an inner space (231) configured to receive and shield a pad layer (15) of the elastic pad (2). Since the at least one inner core layer (221) of the cover (22) includes an elastic material layer, it can efficiently promote the elastic support performance of the cover (22); as the outer wrapping cover (222) removably wraps the at least one inner core layer (221), it is only required to remove and clean the outer wrapping cover (222) when cleaning is to be performed; the stop hems (23) extend about the peripheral edges of the cover (22) to form the inner space (231) for receiving and shielding the pad layer (15) of the elastic pad (2) when the elastic pad (2) is assembled, which can improve convenience in assembling the elastic pad while efficiently reducing the occupied space for storage of the elastic pad (2).
