Optical Housing Bracket with Hinged Attachment for Rack Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical component housing boxes face restrictions in width dimension and installation complexity when housed in racks, particularly when the box size exceeds the width between support pillars or has protruding features on the rear surface.
Innovation Solution
An optical component housing box design featuring a bracket with a fixing portion, an attachment portion, and a hinge portion that allows the attachment portion to stand up relative to the fixing portion after passing between support pillars, enabling the box to be inserted from the rear side and securely attached to the rack without protruding from the side surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the optical component housing box is attached to the rack with the bracket protruding from the side surface, then the attachment is secure, but the width dimension is restricted and installation is complex
Solution Approach 1:
The bracket is designed with a movable attachment portion that can change its position relative to the housing. The attachment portion can be moved between a retracted state (when passing through support pillars) and an extended state (when attached to the rack), allowing the bracket to adapt to different spatial constraints during installation and operation
Solution Approach 2:
The bracket utilizes the depth dimension of the housing by extending inward from the side surface, rather than only protruding outward. This allows the attachment portion to engage with the rack from the rear while maintaining a compact side profile, effectively using the third dimension to resolve the width restriction problem
2Ease of operation
If the optical component housing box is inserted from the front surface of the rack, then the attachment process is straightforward, but boxes with large rear surface dimensions or protrusions cannot be installed
Solution Approach 1:
The bracket is designed to enable insertion from the rear of the rack, which is the opposite of the conventional front-insertion method. The attachment portion is configured to engage with the rack's support pillars from the rear, allowing boxes with large rear surfaces or protrusions to be installed by reversing the insertion direction
Solution Approach 2:
The bracket's attachment portion is pre-configured with a shape that allows it to pass through the support pillars during insertion. The attachment holes are positioned and shaped in advance to accommodate the insertion process from the rear, enabling seamless installation without requiring front-access manipulation
3Device complexity
If the bracket is fixed in a protruding state, then the attachment structure is simple, but the housing box width is constrained by the rack's support pillar spacing
Solution Approach 1:
The bracket incorporates a movable attachment portion that can change its extension state. During insertion, the attachment portion is retracted to minimize the bracket's width profile. Once positioned, it extends to engage with the rack, providing a simple two-state mechanism that resolves the width constraint without significantly increasing structural complexity
Solution Approach 2:
The attachment portion is designed to nest within or alongside the housing structure when retracted, minimizing the overall width occupied by the bracket. This nesting arrangement allows the bracket to fit within the available space during insertion while still providing sufficient engagement capability when extended

AI summary
An optical component housing box including: a housing; and a bracket attached to a side surface of the housing, the bracket including: a fixing portion fixed to the housing; an attachment portion configured to be screwed into one of a plurality of screw holes opened in support pillars provided on both sides of a rack; and a hinge portion, wherein when attaching the optical component housing box to the rack, after the bracket passes between the support pillars by the hinge portion being closed and the attachment portion falling to a fixing portion side as the housing is moved into the rack from a side opposite to a direction in which the attachment portion is to be screwed to the support pillar, the attachment portion is attached to the support pillar in a state of standing up relative to the fixing portion.
