Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for securing electronic devices to computer racks using multiple fasteners are time-consuming and labor-intensive, requiring screws to be inserted and removed for installation and removal.
Innovation Solution
A rack attachment device with a housing, pawl, and slide mechanism that allows for easy locking and unlocking, using a handle to control the pawl's movement into and out of the rack aperture, simplifying the attachment and detachment process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple fasteners (screws) are used to secure electronic devices to computer racks, then the connection strength and reliability are improved, but the installation and removal process becomes time-consuming and labor-intensive
Solution Approach 1:
The fastening function is segmented into two independent parts: a permanent base portion attached to the electronic device, and a removable rack portion attached to the rack. This allows the device itself to remain securely fastened while enabling quick attachment/detachment of the rack interface, resolving the contradiction between connection strength and installation speed.
Solution Approach 2:
The base portion with fasteners is pre-attached to the electronic device during manufacturing or initial setup. This preliminary action eliminates the need for technicians to handle multiple fasteners during installation, reducing labor intensity and time while maintaining secure connection when the rack portion is engaged.
2Reliability
If multiple fasteners (screws) are used to secure electronic devices to computer racks, then the connection strength is improved, but the operational complexity and labor intensity increase
Solution Approach 1:
By dividing the fastening system into a permanent base portion and a removable rack portion, the complex operation of installing multiple fasteners is simplified to a single snap-fit or latch action, dramatically improving ease of operation while maintaining connection strength through the pre-attached base portion.
Solution Approach 2:
The base portion automatically provides the fastening function through its pre-attached state, requiring no additional action from the technician except for engaging the rack portion. This self-service approach eliminates the need for technicians to manually install multiple fasteners, reducing operational complexity.
3Ease of operation
If a simple attachment mechanism is used for mounting electronic devices to racks, then the ease of operation is improved, but the connection strength and reliability may be compromised
Solution Approach 1:
The segmentation of the fastening system allows the base portion to provide strong, permanent attachment to the electronic device using robust fasteners, while the rack portion provides a simple interface for quick connection and disconnection. This resolves the contradiction by distributing different functional requirements to different components.
Solution Approach 2:
The invention merges two distinct attachment mechanisms: a strong permanent fastening system (base portion) and a simple removable interface (rack portion). This combination allows the system to simultaneously achieve both strong connection strength and ease of operation, as each component optimizes for its specific function.

AI summary
A rack attachment device configured for attaching an electronic device to a rack. The rack attachment device includes a housing for coupling to the electronic device, a pawl mounted for movement relative to the housing, a slide mounted for movement relative to the housing, where the slide is positionable to contact the pawl, and a handle extending from the housing and coupled to the slide. In an unlocked position, the handle is in a first handle position and the slide is in a first slide position, such that the slide prevents the pawl from moving toward a rack aperture defined in the rack. In a locked position, the handle is in a second handle position and the slide is in a second slide position, such that the slide permits the pawl to enter the rack aperture when the slide is in the second slide position.
