Adjustable bed base with slotted mounting brackets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional adjustable bed bases have a limited range of angular articulation, making it difficult to access electronic and mechanical components underneath the deck, and users risk damaging linear actuators when trying to manipulate deck members beyond their intended range.
Innovation Solution
The adjustable bed base features slotted mounting brackets that allow additional movement of deck boards beyond the maximum travel of linear actuators, providing enhanced access to components underneath by enabling pins to move along slots, thus protecting the actuators and improving accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the range of angular articulation of deck boards is limited by conventional mounting brackets, then linear actuators are protected from damage, but access to electronic and mechanical components underneath the deck is restricted
Solution Approach 1:
The mounting bracket incorporates a slot that allows the connection point to move dynamically along its length. This dynamic adjustment enables the deck board to achieve greater angular articulation beyond the standard range while still maintaining controlled movement through the slot's geometric constraints, thus improving access without compromising actuator protection
Solution Approach 2:
The slot in the mounting bracket changes the effective range of motion parameter by allowing the connection point to traverse a longer path. This parameter modification enables the deck board to reach more extreme angles while the slot's design ensures the movement remains within safe limits for the linear actuator, resolving the contradiction between access and protection
2Ease of operation
If deck boards are manipulated beyond their intended range of travel, then access to components underneath may be improved, but linear actuators risk damage
Solution Approach 1:
The slot in the mounting bracket acts as a pre-designed cushioning mechanism that absorbs and controls the excess movement. By providing a guided path within the slot, the design allows the deck board to temporarily exceed its normal range without transmitting damaging forces to the linear actuator, thus protecting the actuator while enabling access
3Ease of repair
If the articulated deck is secured to the stationary frame with fixed mounting brackets, then the structure is stable, but service and replacement of components requires turning over or disassembling the bed base
Solution Approach 1:
The mounting bracket is segmented into a fixed portion attached to the frame and a movable portion with the slot that accommodates the linear actuator connection. This segmentation allows the deck board to be independently adjusted along the slot while maintaining the stability of the fixed mounting, improving serviceability without significantly increasing overall structural complexity

AI summary
An adjustable bed base has a stationary frame. An articulated deck is attached to the frame. The deck may be flat or fully articulated depending upon the position of linear actuators which are secured to the frame at one end and to a brace at the other end. The deck may be further inclined due to slotted mounting brackets, thereby allowing access to components below the deck members.
