Modular Bed with Bent Leaf Springs for Cushioning Effect
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional modular beds lack a cushioning effect due to their stiff base materials, which fail to provide adequate support and comfort.
Innovation Solution
The modular bed design incorporates a base frame unit with support frame units featuring leading and trailing bars, mounting frames, a support panel, and bent leaf springs that move between loaded and unloaded positions, generating a combined biasing force to provide cushioning. Additionally, a driving unit allows bars to be elevated, enhancing the cushioning effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional stiff materials are used for the bed base, then structural strength and stability are improved, but cushioning effect deteriorates
Solution Approach 1:
The patent changes the physical state and mechanical properties of the support elements by using spring members that can transition between compressed and extended states. This allows the bed base to dynamically adjust its stiffness parameter, providing both structural strength when needed and cushioning effect when required, thereby resolving the contradiction between strength and comfort.
Solution Approach 2:
The patent combines different material properties by integrating rigid mounting frames with flexible spring members. This composite structure allows the bed base to exhibit both the strength characteristics of rigid materials and the cushioning properties of elastic materials, simultaneously satisfying both requirements.
2Object-generated harmful factors
If a movable support panel is added to provide cushioning, then comfort is improved, but device complexity increases
Solution Approach 1:
The patent divides the bed base into modular support frame units, each with its own mounting frames and spring members. This segmentation allows the cushioning function to be distributed across multiple independent modules, reducing the complexity of any single moving component while collectively providing the desired cushioning effect.
Solution Approach 2:
The patent introduces dynamic elements through the movable support panel and spring members that can adjust their position and stiffness. This dynamic capability allows the structure to adapt to different loading conditions, providing cushioning when needed while maintaining structural integrity, thereby justifying the increased complexity through functional benefits.
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
The modular bed effectively provides a cushioning effect by using bent leaf springs and a movable support panel, improving comfort and support, while the driving unit further enhances the bed's adjustability and usability.
Implementation Method 1
Each of the upper and lower curved segments has a deflection area in which the respective upper and lower curved segments produce a combined biasing force so as to provide cushioning effect for the support panel

AI summary
A modular bed includes a base frame unit and a plurality of support frame units mounted on the base frame unit to be displaced from each other. Each of the support frame units has a lead bar, a trailing bar, four mounting frames, a support panel, and four bent leaf springs each coupling the support panel to a respective one of the mounting frames so as to provide cushioning effect for the support panel in response to movement of the support panel from an unloaded position to a loaded position.
