Pneumatic Tool Holder Keyhole Compartment Debris Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pneumatic tools are prone to contamination and degradation when stored, as dust and debris can enter through the quick coupling, leading to malfunction, and existing solutions like rubberized or plastic caps are ineffective in preventing this.
Innovation Solution
A pneumatic tool holder apparatus with a housing featuring keyholes and interior compartments that prevent debris from entering the tool, where the keyholes have an enlarged side to receive the tool's coupling device and a non-enlarged side smaller than the collar, ensuring the coupling device is securely locked within the compartment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If rubberized or plastic caps are placed over the male portion of the quick coupling, then the tool is protected from contamination, but the caps are prone to inadvertently falling off
Solution Approach 1:
The quick coupling device is inserted through the bottom plate and nested within an interior compartment of the housing. The compartment is configured to receive the coupling device and prevent removal, effectively nesting the coupling within a protective enclosure that eliminates the need for separate caps while preventing contamination.
Solution Approach 2:
The bottom plate with its keyhole-shaped openings serves as an intermediary structure between the external environment and the pneumatic tool's coupling device. The keyhole geometry with enlarged and non-enlarged sides acts as a mediator that allows insertion while preventing removal, creating a secure interface between the housing and coupling.
2Ease of operation
If the quick coupling is left open for easy connection and disconnection, then the tool is easy to operate, but dust and debris can enter and cause malfunction
Solution Approach 1:
The housing is segmented into multiple interior compartments, each corresponding to a keyhole opening. This segmentation allows each compartment to independently protect a specific coupling device while maintaining overall accessibility. The bottom plate is segmented with multiple keyhole-shaped openings, creating discrete access points that prevent debris entry while allowing tool connection and disconnection.
3Ease of operation
If pneumatic tools are stored in open locations for accessibility, then the tool is easily accessible, but the tool deteriorates over time due to environmental exposure
Solution Approach 1:
The housing combines multiple functions into a single integrated structure: it provides protective enclosure, debris prevention through interior compartments, and secure retention of the coupling device. The bottom plate with keyholes merges the functions of access control and protection, creating a unified storage solution that extends tool service life while maintaining accessibility.

AI summary
A pneumatic tool holder apparatus and related methods of storing pneumatic tools are disclosed. The pneumatic tool holder apparatus has a housing having a bottom plate. A plurality of keyholes is formed in the bottom plate. Each of the plurality of keyholes have an enlarged side and a non-enlarged side, where the enlarged side is sized to receive an end of a pneumatic tool coupling device and the non-enlarged side is sized smaller than a collar on the end of the pneumatic tool coupling device. A plurality of interior compartments is formed within the housing. Each interior compartment corresponds to one of the plurality of keyholes. When the end of the pneumatic tool coupling device is inserted through a keyhole and into an interior compartment, the interior compartment prevents debris from gaining access to a pneumatic interior of a pneumatic tool.
