Temporary Fastener Support Module With Retractable Locking Holder
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automated devices for setting temporary fasteners are inconvenient, inflexible, and prone to losing fasteners during movement due to their large size and requirement for back-and-forth movement between storage and setting zones.
Innovation Solution
A device with a support module that houses a temporary fastener, featuring locking means that can move between a locking position to secure the fastener and a rest position to allow passage, integrated with a supply system like a cartridge belt, optimizing the automated setting of temporary fasteners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a robotic arm is used to transport temporary fasteners between storage zone and setting zone, then automated setting is achieved, but the device becomes large and inflexible with risk of losing fasteners during movement
Solution Approach 1:
The patent merges the storage function and setting function into a single integrated support module. The temporary fastener is stored in a recess within the module and can be directly engaged by locking means (locking lugs) that are part of the same module, eliminating the need for separate robotic arm transport between distant storage and setting zones. This integration reduces device size while maintaining automated operation.
2Extent of automation
If a robotic arm moves between storage zone and setting zone, then automated setting is achieved, but flexibility is reduced and fastener loss risk increases
Solution Approach 1:
The locking means (locking lugs) are pre-positioned within the support module in a ready state. When the temporary fastener is placed in the recess, the locking lugs can immediately engage with corresponding features on the fastener body without requiring transport or repositioning. This preliminary positioning of locking components ensures secure retention from the moment the fastener is inserted, eliminating the risk of loss during movement.
3Reliability
If locking means are deployed inside the module to secure the temporary fastener, then fastener retention is improved, but the fastener cannot pass through the module
Solution Approach 1:
The locking lugs are designed as movable components that can dynamically change their position. They can be deployed (extended) to engage with the temporary fastener and secure it within the recess, or retracted (withdrawn) to allow the fastener to pass through the module. This dynamic capability allows the same locking means to provide both secure retention when needed and unobstructed passage when required, making the module adaptable to different operational states.
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 improves the reliability and security of temporary fastener setting by better holding the fasteners during movement and setting, and allows for an integrated supply system, enhancing the efficiency of the automated process.
Implementation Method 1
said piston comprising a portion tilted with respect to said axis, said tilted portion acting on said locking element when said piston moves into its release position to move said locking element into its rest position
Implementation Method 2
a device according to the invention comprises second elastic return means tending to return said locking member to its locking position

AI summary
A device for setting a temporary fastener. The temporary fastener includes a body with an expandable/retractable end and a rotary element capable of being driven in rotation so as to cause the expandable/retractable end to expand/retract. The device includes a support module that is able to house a temporary fastener and has a holder for holding the temporary fastening inside the module. The holder is movable between at least: a locking position in which the holder is deployed inside the module so as to cooperate with a temporary fastener placed in the module in order to prevent it from moving in translation inside the module, and a rest position in which the holder is retracted so as to allow a temporary fastener to pass through the module.
