Slotted Threaded Bolt Fastener for Quick Lateral Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening elements for threaded bolts are time-consuming to mount, requiring numerous rotations and lacking in precise adjustment capabilities.
Innovation Solution
A plastic fastening element with a laterally open threaded bore hole and axial slot allows for quick mounting by lateral fitting, with optional locking mechanisms such as narrowed slots, spring legs, or flexible tongues to secure the block on the bolt, facilitating precise positioning and secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the fastening element is mounted by screwing onto the threaded bolt, then the block can be securely attached to the bolt, but the mounting process becomes time-consuming requiring numerous revolutions
Solution Approach 1:
The invention changes the mounting direction from axial (screwing along the bolt length) to lateral (inserting through the side opening). The block is inserted laterally through an opening in its side wall onto the threaded bolt, reducing the number of rotational movements required while maintaining secure attachment through threading engagement.
Solution Approach 2:
The fastening element is divided into functional segments: a lateral opening for quick insertion, threaded grooves for secure engagement, and a locking mechanism (narrowing slot or spring legs) to prevent disengagement. This segmentation allows the mounting process to be separated into quick lateral insertion followed by automatic locking.
2Ease of manufacture
If the block is made of plastic material, then material efficiency and cost are improved, but the structural strength may be reduced
Solution Approach 1:
The invention changes the material parameter from metal to plastic, utilizing modern engineering plastics that provide sufficient strength while offering manufacturing advantages. The plastic material allows for integrated molding of complex features like lateral openings, threaded grooves, and locking mechanisms, reducing assembly steps and material waste.
Solution Approach 2:
The block can be formed as a composite structure combining plastic with reinforcing elements or using fiber-reinforced plastics to maintain structural strength while preserving the manufacturing efficiency and cost benefits of plastic materials.
3Ease of operation
If the lateral opening is made wide for easy insertion, then ease of operation is improved, but the locking effect is reduced
Solution Approach 1:
The lateral opening is designed to be wide for easy insertion, then dynamically transitions to a narrowed configuration through self-locking mechanisms. The narrowing slot or spring legs automatically contract after insertion to secure the bolt, providing both ease of operation and reliable locking.
Solution Approach 2:
Instead of making the opening narrow and forcing the bolt through, the invention inverts the approach by providing a wide opening for easy insertion, then using elastic deformation or mechanical locking features to close and secure the opening after the bolt is in place.
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
Enables rapid and accurate mounting of the fastening element on threaded bolts with reduced rotational effort, ensuring secure attachment even under load, and allowing for efficient material usage while maintaining structural integrity.
Implementation Method 1
Spring legs can spring inward from the latter, and the spring legs can back off behind the threads of the threaded bore hole when the end of a bolt is inserted laterally and spring back when the end position of the insertion path of the end of the bolt in the threaded bore hole is reached

AI summary
The description concerns a fastening element for a bolt provided with a thread, in particular a stud bolt, comprising a block which is made of plastic, provided with a threaded bore hole and can be screwed onto the bolt. The fastening element is characterized in that the threaded bore hole is open laterally by means of an axial slot in such a way that the block can also be fitted on the threaded bolt laterally.
