Modular Slat Spring System for Replaceable Furniture Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing furniture spring systems are not removable, replaceable, or adjustable, leading to difficulties in changing cushioning firmness and storage space configurations without damaging the furniture, and they often require costly reconstruction when springs break.
Innovation Solution
Modular furniture spring systems that are easily replaceable, adjustable, and customizable, featuring slats that can be extended or contracted, and include a lid that covers storage spaces without compromising comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If spring systems are permanently fixed within furniture items, then structural stability is improved, but ease of repair and adaptability deteriorate
Solution Approach 1:
The spring system is divided into individual replaceable slats rather than a permanently fixed unit. Each slat can be independently removed and replaced by lifting it out from beneath the cushion, allowing easy repair without deconstructing the entire furniture item while maintaining structural stability through the array of slats working together
2Stability of the object's composition
If spring systems are permanently fixed within furniture items, then structural stability is improved, but adaptability deteriorates
Solution Approach 1:
The spring system transitions from a fixed, static configuration to a dynamic, adjustable one. Users can selectively add or remove slats to change the firmness level according to their preferences, allowing the same furniture item to adapt to different users and needs while maintaining structural stability through the modular slat design
3Object-affected harmful factors
If rigid barriers are used to protect stored items, then protection of stored items is improved, but comfort deteriorates
Solution Approach 1:
The storage barrier transitions from a rigid structure to a flexible fabric material that drapes over the slats. This flexible fabric barrier protects stored items from direct contact and potential damage while allowing the slats to flex and provide cushioning, thus maintaining both protection and comfort
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
Enables users to customize firmness and size of the spring system to suit their preferences, allows easy replacement without deconstruction, and protects stored items while maintaining comfort and functionality.
Implementation Method 1
a flexible middle portion extending between the first end and the second end. The catch engages the retention member to retain the slat to the frame and is configured to slide back-and-forth relative to the retention member as the middle portion elastically flexes downward and upward in response to forces intermittently pushing downward on the slat during use

AI summary
Furniture spring systems are configured to provide support for different sized modular seating systems and/or modular bed systems. Slats extend between opposing frame or rail members to provide support to the seating or bed system. The slats have a catch disposed at a first or second end. In the seating and/or bed frame systems, the catch engages a retention member to retain the slat to the frame or rail. Adjustable bed frame systems employing such slats comprise modular bed frames and adjustable head boards and foot boards. Bed frames employing the slats and headboards/footboards thereof adjust in length or width in a variety of different manners. Adjustable bed frames adjust through the use of telescoping members, filler blocks and/or elongate end blocks that have different sizes from the standard uniform elongate support blocks employed in a bed frame.
