Furniture with removable electronics rack
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional furniture, such as lecterns, face difficulties in accessing internally mounted electronics, leading to haphazard placement and potential heating issues due to the complexity of wiring and equipment arrangement.
Innovation Solution
A removable electronics rack system is integrated into the furniture, allowing for sliding movement between a stowed and access position, with a guide assembly limiting travel to a horizontal direction and a locking mechanism for secure positioning, enabling easy access and removal of the rack for improved accessibility and cable management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electronics are mounted within the furniture body on fixed shelves, then equipment is protected and wiring is hidden, but access to equipment becomes difficult and placement becomes haphazard
Solution Approach 1:
The rack is designed to be movable between a retracted position (within the furniture body) and an extended position (partially outside the shell), allowing users to easily access equipment when needed while maintaining protection when retracted. The guide assembly enables this dynamic movement along the horizontal axis.
2Adaptability or versatility
If multiple electrical components are added to meet increasing needs, then functionality improves, but equipment placement becomes haphazard and wiring complexity increases
Solution Approach 1:
The rack is divided into multiple levels or segments that can independently accommodate different electronic components. This segmentation allows organized placement of multiple devices with their associated wiring, preventing haphazard arrangement and making cable management more systematic.
3Volume of moving object
If equipment is densely packed within the furniture body, then space utilization improves, but heating issues arise
Solution Approach 1:
The rack extends in the horizontal dimension beyond the furniture body when in the extended position, distributing equipment across a larger volume and improving air circulation around components. This dimensional expansion reduces heat accumulation while maintaining efficient space utilization when the rack is retracted.
4Ease of operation
If the rack is made removable for easy access, then equipment accessibility improves, but the rack may be accidentally removed or misplaced
Solution Approach 1:
The guide assembly acts as an intermediary mechanism between the rack and the furniture body. It allows controlled movement of the rack while providing guidance and limitation to prevent accidental removal or misplacement, ensuring the rack remains securely associated with the furniture during normal operation.

AI summary
A piece of furniture, such as a lectern, has a shell with an opening. A rack for electronic equipment is mounted within the shell. The rack can be slid between a stowed position in which the rack is entirely within the furniture and an access position in which the rack extends through the opening and is partially outside the shell.
