Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional spring mattresses are non-replaceable and lack effective ventilation options, leading to increased economic burden and environmental impact, as well as inadequate thermal regulation, posing safety risks during extreme temperatures.
Innovation Solution
A combination mattress design featuring a separable structure with elastic body, detachable side covers, and interchangeable pad bodies, utilizing zippers or Velcro for connectivity, allowing for adjustable ventilation and pad type changes to enhance breathability and practicality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional spring mattresses are combined into one body, then structural stability is improved, but replaceability and adaptability deteriorate
Solution Approach 1:
The mattress is divided into separate components: an elastic body (spring layer), a pad body, and a cover. These components can be independently replaced or adjusted, allowing users to change the pad body or cover without replacing the entire mattress, thus improving replaceability while maintaining structural stability through the fixed elastic body framework.
2Ease of manufacture
If traditional spring mattresses are combined into one body, then manufacturing simplicity is improved, but economic burden and environmental impact worsen
Solution Approach 1:
By segmenting the mattress into replaceable components, particularly the pad body and cover, users can replace only the worn or soiled parts rather than the entire mattress. This reduces waste of functional components and decreases the frequency of complete mattress replacements, thereby reducing economic burden and environmental impact.
3Ease of manufacture
If traditional spring mattresses have fixed design, then manufacturing cost is reduced, but thermal regulation capability deteriorates
Solution Approach 1:
The cover is designed to be detachable and replaceable, allowing users to change it according to seasonal temperature variations. In summer, breathable covers can be used to improve ventilation; in winter, warmer covers can be attached. This dynamic adaptability improves thermal regulation without requiring complex built-in systems.
Solution Approach 2:
The cover serves multiple functions: it provides thermal insulation, enables ventilation through detachable design, and protects the internal components. By making the cover universally applicable across different seasons and conditions through replacement options, the mattress achieves improved thermal regulation while maintaining manufacturing simplicity.
4Device complexity
If traditional spring mattresses lack ventilation design, then structural simplicity is improved, but breathability and comfort deteriorate
Solution Approach 1:
The cover is segmented into detachable sections with ventilation holes, allowing air to circulate through the mattress. This segmented design maintains overall structural simplicity while significantly improving breathability and comfort, especially during hot weather.

AI summary
A combination mattress includes an elastic body, a bottom cover, longitudinal side covers, transverse side covers, and a pad body, where the bottom cover, longitudinal side covers and transverse covers are in sheet shape, the periphery of each of which is configured with a connecting element; the bottom periphery of the pad body is configured with a connecting element, and the upper edge thereof a shielding sheet. Upon assembly, the bottom cover, two longitudinal side covers and two transverse side covers are covered on the elastic element, and the pad body is placed on the elastic body to form a mattress. The detachable longitudinal side covers and transverse side covers are used to make the mattress have air permeability in different directions, and the detachable pad body allows the replacement thereof with a different type of pad body, thereby improving the practical value of the mattress.
