Toolbox Latch Assembly with Retractable Cable
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in securely storing and managing cumbersome tools and equipment, particularly when needing to temporarily leave them unattended, as existing solutions like cables and locks can be cumbersome to handle and may be lost or awkward to use.
Innovation Solution
A retractable cable securement assembly is integrated into a toolbox, featuring a reel, cable retention knob, and a latch assembly that operates based on the open or closed position of the lid, allowing for easy cable management and securement through a receiving port and exit aperture, with a mechanical actuator ensuring the latch's release or capture functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cable or chain is used to secure tools and equipment, then security against theft is improved, but ease of operation deteriorates due to cumbersome handling and risk of loss
Solution Approach 1:
The patent combines the cable storage function, cable dispensing function, and security function into a single integrated assembly. The cable is stored on a reel that is part of the latch assembly, allowing the cable to be automatically stored and secured when the lid is closed, eliminating the need for separate cable storage and reducing handling complexity.
Solution Approach 2:
The cable reel assembly provides self-service by automatically winding and storing the cable when the lid is closed, and by providing the cable when the lid is opened. The spring-loaded reel mechanism automatically reels in the cable, eliminating the need for manual winding or separate storage actions by the user.
2Ease of operation
If a retractable cable assembly is integrated into the toolbox, then ease of operation is improved, but device complexity increases due to additional mechanical components
Solution Approach 1:
The cable reel assembly is merged with the existing latch assembly, sharing common structural elements and mounting points. The reel is mounted within the latch assembly housing, and the cable passes through the latch mechanism, integrating multiple functions into a single compact unit rather than adding separate independent components.
Solution Approach 2:
The latch assembly serves multiple functions: it provides the primary latching mechanism for securing the lid, and simultaneously houses the cable reel for cable storage and dispensing. The receiving port structure is used both for latch engagement and for guiding the cable, reducing the need for separate dedicated components for each function.
3Ease of operation
If the latch assembly is made operable dependent on lid position, then ease of operation is improved through automatic engagement, but device complexity increases due to the actuator mechanism
Solution Approach 1:
The latch assembly transitions from a static component to a dynamic one that automatically changes state based on lid position. The actuator mechanism converts the lid's linear motion into rotational motion of the latch, enabling automatic engagement and disengagement without requiring separate control mechanisms or complex sensing systems.
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 solution provides a convenient and secure method for storing and retrieving tools by allowing the cable to be easily retracted or extended, ensuring the tools are securely locked when the lid is closed and easily accessible when open, addressing the challenges of handling and securing cumbersome equipment.
Implementation Method 1
A plunger lift spring as a further part of the actuator may be operable to mechanically bias the plunging rod, when the plunging rod has been displaced downward so as to lend a lifting force operable to lift the plunging rod when the lid is opened for clearing the latch from the path as defined by the inner diameter of the receiving port.

AI summary
A storage box includes a plurality of walls that define an interior. A cable housing may be secured to an interior wall of the storage box, with a reel secured therein for rotational winding and unwinding of a cable. A cable retention knob on the distal end of the cable enables withdrawal of the cable external the storage box. A receiving port on a wall of the storage box can receive at least a portion of the cable retention knob. A latch assembly is operatively disposed proximate the receiving port and is selectively configurable, dependent on an open or close condition of a lid. The latch assembly is operatively and selectively configured to release the cable retention knob when the lid is open and to enable spring-biased capture of the cable retention knob when the lid is closed and when the cable retention knob is seated in the receiving port.
