Solution Overview

Problem

Conventional sleeping bags for children lack structural strength to support a reclining body, making them uncomfortable when used directly on the floor without a mattress, and often get kicked off during sleep.

Innovation Solution

A bedding assembly comprising a cushion with a cushion cover and a top cover, coupled via a coupling unit, which creates a reclining space that includes a cushion space and an insert space, using zippers or buttons for secure closure to maintain temperature and comfort, and allows for adjustable fill to accommodate seasonal changes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a conventional sleeping bag is used without a mattress, then portability is improved, but comfort and structural strength deteriorate

Engineering Contradiction:
ImproveportabilityVSAvoidstructural strength
Core Design Contradiction:
Adaptability or versatilityVSStrength

Solution Approach 1:

The bedding assembly is divided into separate components: a cushion, a cushion cover, and a top cover that can be used independently or combined. This segmentation allows the cushion to provide structural support when needed while maintaining portability through separate packing.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The cushion acts as an intermediary element between the sleeping bag and the floor, providing necessary structural support and comfort when the sleeping bag is used without a mattress, thereby resolving the contradiction between portability and structural strength.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If a sleeping bag is placed on the floor without a mattress, then portability is improved, but comfort deteriorates

Engineering Contradiction:
ImproveportabilityVSAvoidcomfort
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The bedding system is segmented into a cushion component and a sleeping bag component, allowing the cushion to be inserted into the sleeping bag to provide comfort when needed, while maintaining the ability to use the sleeping bag alone for maximum portability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The bedding assembly allows dynamic adjustment of comfort level by inserting or removing the cushion from the sleeping bag, enabling the user to adapt the comfort level to the specific situation while maintaining portability.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If a sleeping bag is used without a mattress, then portability is improved, but reliability deteriorates

Engineering Contradiction:
ImproveportabilityVSAvoidcomfort support reliability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The cushion is pre-formed with the appropriate shape and firmness to provide reliable body support, and can be preliminarily inserted into the sleeping bag before use to ensure consistent and reliable comfort support whenever the sleeping bag is used without a mattress.

Inventive Principle:
Principle #10Preliminary action

4Ease of operation

If a top cover is made loose-fitting, then comfort is improved, but the top cover gets kicked off during sleep

Engineering Contradiction:
ImprovecomfortVSAvoidcover position stability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The coupling mechanism provides dynamic adjustment capability, allowing the top cover to be securely attached during the day and easily detached or adjusted during sleep to maintain both comfort and positional stability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The coupling strength between the top cover and cushion can be changed by using different coupling mechanisms (such as zippers, buttons, or magnetic attachments), allowing the user to adjust the firmness of the fit to prevent the cover from being kicked off while maintaining comfort.

Inventive Principle:
Principle #35Parameter changes

AI summary

A bedding assembly includes a cushion, a cushion cover, a top cover and a coupling unit. The cushion has opposite lateral surfaces. The cushion cover accommodates the cushion and has opposite first and second cover portions that are respectively adjacent to the lateral surfaces of the cushion. The top cover is laid on top of the cushion cover and has opposite first and second side portions that are respectively adjacent to the first and second cover portions of the cushion cover. The coupling unit includes a first coupling subunit that separably couples the first cover portion to the first portion, and a second coupling subunit that separably couples the second cover portion to the second side portion.
