Retractable Tool Holder for Secure Small-Part Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tools and tool parts are prone to loss during use on construction sites, leading to time-consuming searches, disruptions, and safety risks, with existing securing mechanisms being complex, obstructive, or impractical for small tools and tool parts.
Innovation Solution
A device comprising a container with a self-retracting mechanism and a flexible safety tendon, attached to a holder via a fastening means, ensures the container is securely attached to the user, preventing loss while allowing easy access and use of tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a self-retracting mechanism with multiple locking mechanisms is used to secure tools, then the security and reliability of tool attachment is improved, but the device complexity and ease of operation deteriorate
Solution Approach 1:
The patent extracts the essential security function from complex multi-locking mechanisms, retaining only the necessary attachment and detachment capabilities. The holder provides secure attachment through a simplified mechanism that maintains reliability while reducing complexity, allowing tools to be securely held during work but easily released when needed.
Solution Approach 2:
The tool belt holder is designed to automatically retain tools during movement and work without requiring active engagement mechanisms. The passive retention system uses the natural position and gravity of tools on the belt to maintain security, eliminating the need for complex active locking mechanisms while preserving reliability.
2Quantity of substance
If a tool bag with securing straps is used to carry multiple tools, then the quantity of tools that can be carried is improved, but the weight and ease of operation deteriorate
Solution Approach 1:
Instead of carrying all tools in a single heavy bag, the patent segments tools into individual slots on the tool belt holder. Each tool can be independently accessed and removed without handling other tools or the entire container, significantly improving ease of operation while maintaining the ability to carry multiple tools.
Solution Approach 2:
The patent transitions from vertical stacking of tools in a bag to horizontal distribution across the tool belt. This dimensional change allows tools to be spread out and easily accessible from the front, eliminating the need to dig through a bag and improving accessibility while maintaining tool capacity.
3Ease of operation
If tools are stored in pockets for easy access, then the ease of operation is improved, but the reliability and safety deteriorate due to loss risk
Solution Approach 1:
The patent merges the advantages of pocket storage (easy access) with secure retention by integrating tools into a belt-mounted holder that is worn close to the body. Tools remain easily accessible like in pockets but are securely retained through the belt attachment mechanism, eliminating the loss risk associated with loose pocket storage.
4Reliability
If a robust safety lanyard with multiple locking mechanisms is used to secure tools, then the reliability of tool attachment is improved, but the ease of operation and device complexity worsen
Solution Approach 1:
The patent extracts only the essential security function from robust safety lanyards with multiple locks, retaining simple attachment and detachment capabilities. The holder provides secure tool retention during work but allows quick release when needed, maintaining reliability while dramatically improving ease of operation by removing unnecessary locking mechanisms.
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 device minimizes the risk of losing tools and tool parts by ensuring they remain attached to the user, reducing the risk of injury and maintaining accessibility without obstructing use, through a simple and reliable securing mechanism.
Implementation Method 1
The self-retracting mechanism includes a spring-loaded return winch with which the safety lanyard can be wound up within the mechanism
