Solution Overview
Problem
Existing pocket-spring mattresses lack the ability to provide different hardness levels and support levels in different regions, failing to cater to users of varying body shapes and weights, and are costly to replace when individual springs fail.
Innovation Solution
A ready-to-assemble bed design with interchangeable spring-based resilient chunks of varying hardness levels, allowing users to customize support based on personal needs and enabling individual replacement of damaged components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional one-piece mattresses are used, then manufacturing is simple and cost-effective, but the entire mattress must be discarded when even one spring fails, increasing cost and waste
Solution Approach 1:
The mattress is divided into multiple independent base members (first base member, second base member, etc.) that can be assembled together. Each base member contains its own springs, allowing individual replacement when a spring fails in one base member, eliminating the need to discard the entire mattress while maintaining manufacturing simplicity through standardized modular components
2Adaptability or versatility
If uniform springs are used throughout the mattress, then manufacturing is simplified, but the mattress cannot provide different support levels for different body regions or users of different body shapes
Solution Approach 1:
Different base members are equipped with springs of different specifications (different hardness levels, different support characteristics) according to the specific support needs of different body regions. For example, base members under heavier body parts can use stiffer springs, while base members under lighter areas use softer springs, providing localized quality adaptation without requiring complex overall redesign
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Provides customizable support for different body parts and reduces environmental waste by allowing selective replacement of faulty parts, enhancing user comfort and sustainability.
Implementation Method 1
The springs bear loads and resile independently of each other, so they can support different portions of a human body with different strength levels

AI summary
A ready-to-assemble bed includes a bed base, a replaceable resilient cushion, a contact pad, and a headboard. The replaceable resilient cushion is placed on the bed base and has a first encasement that has spring-based resilient chunks removably filled therein. The contact pad is placed on the replaceable resilient cushion and detachably combined with the replaceable resilient cushion. The contact pad includes a second encasement that has a support member removably filled therein. The headboard is detachably combined with the bed base. Thereby, a user of the ready-to-assemble bed can make up the replaceable resilient cushion with the spring-based resilient chunks having different hardness levels according to practical needs and thereby provide the user's different body portions with suitable support.
