Solution Overview

Problem

Conventional cable arm brackets in computer systems are non-removable, leading to inflexibility in cable management, increased costs, and interference with other components, particularly in systems with limited space.

Innovation Solution

A removable cable arm bracket with a spring sheet mechanism that allows the bracket to be locked and unlocked from inner rails without tools, featuring apertures and projections that secure the bracket in place and enable easy removal, allowing for adjustable length and flexible installation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the cable arm bracket is fixed to the inner rail, then the bracket provides stable cable routing, but the bracket cannot be removed and interferes with other components

Engineering Contradiction:
Improvecable routing stabilityVSAvoidbracket removability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The bracket transitions from a fixed state to a removable state through a spring sheet mechanism. The spring sheet can be in a locked position securing the bracket to the inner rail, or an unlocked position allowing removal, enabling dynamic adaptability while maintaining stability when needed.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The spring sheet mechanism changes the mechanical state of the bracket attachment. By altering the position of the spring sheet between locked and unlocked states, the bracket's attachment parameter changes, allowing it to be either firmly fixed or easily removable as needed.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If the cable arm bracket is fixed to the inner rail, then the bracket maintains secure attachment, but it increases cost and reduces space flexibility

Engineering Contradiction:
Improveattachment securityVSAvoidsystem configuration flexibility
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The spring sheet mechanism provides self-locking and self-unlocking functionality without requiring external tools or complex mechanisms. The spring force automatically maintains the bracket in the locked position during normal use, and allows easy release when needed, simplifying the overall system while maintaining security.

Inventive Principle:
Principle #25Self-service

3Stability of the object's composition

If the bracket is non-removable, then cable routing is stable, but it prevents flexible cable management in limited space systems

Engineering Contradiction:
Improvecable routing stabilityVSAvoidcable management flexibility
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The bracket system becomes dynamic, allowing operators to switch between a stable fixed state during normal operation and a removable state when cable management adjustments are needed. This dynamic capability provides both stability and flexibility as required by different operational scenarios.

Inventive Principle:
Principle #15Dynamics

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 removable cable arm bracket provides greater flexibility in cable management, allowing for more space within computer systems and enabling different length configurations as needed, while maintaining secure attachment without requiring tools.

Implementation Method 1

The spring sheet is configured to bias into a second position. The spring sheet has a ridge at the second end that obstructs at least part of at least one aperture of the at least two apertures with the spring sheet in a first position.

AI summary

The present disclosure is directed to a removable cable arm bracket for attachment to an inner rail of a computer system. The cable arm bracket includes a spring sheet that can be biased for securing and removing the cable arm bracket from the inner rail. The spring sheet secures a projection from the inner rail within an aperture of the cable arm bracket to secure the cable arm bracket to the inner rail. Biasing of the spring sheet allows the projection to be removed from the aperture.
