Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cushions are difficult to clean, lack ventilation and heat dissipation, and are not effective in sterilizing bacteria and mites, leading to short service life and discomfort.
Innovation Solution
A cushion supporting structure with self-adaptive units comprising flexible bearing members and elastic members that deform under pressure, allowing for easy cleaning and sterilization, while providing ventilation and heat dissipation, and maintaining durability and long-lasting elasticity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional filling materials (sponge, latex) are used in cushions, then soft support is provided, but cleaning becomes difficult and bacteria/mites cannot be effectively eliminated
Solution Approach 1:
The patent removes traditional filling materials (sponge, latex) from the cushion structure and replaces them with elastic members (springs, rod bodies) that provide support without retaining soil or bacteria. This extraction of the problematic filling material while maintaining the support function resolves the contradiction between soft support and cleaning ease.
2Device complexity
If traditional filling materials are used, then cushion structure is simple, but ventilation and heat dissipation are insufficient
Solution Approach 1:
The patent employs elastic members with porous or open structures (springs, rod bodies with gaps) that create ventilation channels within the cushion. These porous structures allow air circulation for improved heat dissipation while maintaining structural simplicity, resolving the contradiction between simple structure and temperature control.
3Temperature
If elastic members are added to create self-adaptive units, then ventilation and heat dissipation improve, but device complexity increases
Solution Approach 1:
The elastic members serve multiple functions simultaneously: they provide mechanical support, enable ventilation through their porous structure, facilitate heat dissipation, and allow adaptive deformation. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity while achieving improved temperature control.
4Duration of action of stationary object
If elastic members are used instead of traditional fillers, then service life is extended and sterilization is easier, but manufacturing complexity increases
Solution Approach 1:
The patent changes the fundamental parameter of the filling material from soft, deformable materials (sponge, latex) to rigid or semi-rigid elastic members (springs, rod bodies) with high durability. This parameter change extends service life and enables easier sterilization while the modular nature of the elastic members keeps manufacturing processes relatively simple.

Implementation Method 1
the elastic member is deformed; when the pressure is removed, the elastic member is reset under its elasticity

AI summary
A self-adaption breathable cushion comprises a fixed base and a plurality of self-adaptive units integrated side by side and disposed on the fixed base; each of the adaptive units comprises a strap and an elastic member, the elastic member supports the strap to tension above the fixing base; when the strap is pressed and recessed, the elastic member deforms, so that the whole self-adaptive unit moves downwards; when the pressure is removed, the elastic member is reset, and the strap is also reset. The self-adaptive breathable cushion can be deformed self-adaptively according to the weight of a human body to be borne, so as to be attached to the human body, making the human body more comfortable.
