Slack Cable Storage with Movable Retainer for MDU Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multiple dwelling unit (MDU) applications, there is a need for a slack cable storage apparatus that provides easy access to fiber optic cables of varying lengths, as the length required for connections to network hubs can be unknown and may vary significantly.
Innovation Solution
A slack cable storage apparatus featuring a housing with a spooling assembly and a hinged retainer that allows for secure storage and easy access to fiber optic cables, where the retainer can be moved between a securing and access configuration to manage the cable spooled around the spooling members within the enclosure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If fiber optic cable is stored in traditional cable storage enclosures, then the cable can be stored securely, but the access to the cable becomes difficult and the cable length cannot be easily adjusted
Solution Approach 1:
The patent applies the dynamics principle by making the retainer movable between a first position that secures the cable and a second position that provides access to the cable. This dynamic positioning allows the same component to serve both storage security and accessibility functions, resolving the contradiction between secure storage and easy access.
Solution Approach 2:
The patent segments the cable storage function into distinct components: a spooling member for cable winding, a movable retainer for securing, and a housing for containment. This segmentation allows each component to be optimized independently - the spooling member for easy cable access and the retainer for secure holding - thereby improving overall ease of operation without increasing system complexity.
2Adaptability or versatility
If fixed length cable is installed, then the installation is simple, but the cable cannot accommodate varying distances to network hubs
Solution Approach 1:
The movable retainer creates a dynamic storage system where cable length can be easily adjusted by moving the retainer along the spooling member. This allows the same storage apparatus to accommodate varying cable lengths for different distances to network hubs, providing adaptability without complicating the installation process.
Solution Approach 2:
The spooling assembly with movable retainer serves multiple functions: it stores cable, secures cable, and allows length adjustment. This multi-functionality enables the same device to handle varying cable length requirements for different MDU applications, improving adaptability while maintaining ease of manufacture and installation.
3Ease of operation
If technician needs comfortable operating space, then the installation and repair work is easier, but the storage apparatus must be larger to provide adequate slack cable
Solution Approach 1:
The movable retainer allows the cable to be dynamically positioned and secured at different locations along the spooling member. This dynamic mechanism provides adequate slack cable for technician operating space while maintaining a compact storage apparatus volume, as the retainer can be positioned to provide exactly the amount of cable needed without requiring excessive storage capacity.

AI summary
A slack cable storage apparatus includes a housing having a top, a bottom, sides, a back extending between the top, bottom and sides thereby defining a storage volume and a cable opening extending through the housing. A spooling assembly is located in the storage volume. The spooling assembly includes a spooling member about which a cable is to be wound. A retainer is moveably connected to the spooling member. The retainer has a cable storing configuration where the retainer overlies a spooling volume adjacent the spooling member and a cable access configuration where the retainer is moved to allow access to the cable when spooled about the spooling member.
