Angled Pivot Snap Fastener for Secure Substrate Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening devices for substrates, such as ship decks or car surfaces, often cause inconvenience and injuries due to permanently present projections, and fail to provide secure, easy-to-use, and releasable fastening solutions that can withstand stress without unintentional release.
Innovation Solution
A fastening device comprising two elements with hooking parts that can engage at an angle and pivot to create stress, featuring a hooking part around the first element and a local hooking part on the second, allowing for secure fastening and easy release without tools, using resilient materials like metal or polymers for durability and ease of production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If projections are permanently present on the substrate for fastening, then fastening capability is provided, but inconvenience and injuries are caused
Solution Approach 1:
The fastening system is divided into two separate elements: a first element mounted on the substrate and a second element mounted on the object. This segmentation allows the fastening function to be distributed, eliminating the need for permanent projections on the substrate while maintaining reliable fastening capability through the interaction of the two elements.
Solution Approach 2:
The harmful projections are extracted from the substrate by transferring the fastening function to a separate first element that can be mounted on the substrate. This extraction removes the source of inconvenience and injuries while preserving the essential fastening capability through the two-element system.
2Reliability
If the fastening device uses resilient parts that snap into each other, then secure fastening is achieved, but complexity of the device increases
Solution Approach 1:
The hooking part and resilient snapping part are combined into a single integrated fastening mechanism where the hooking part of one element engages with the resilient part of the other element. This merging reduces the number of separate components while maintaining secure fastening through the snap-action engagement.
Solution Approach 2:
The resilient parts are designed to automatically snap into engagement with the hooking parts through their own elastic deformation, without requiring additional locking mechanisms or complex assembly steps. This self-service mechanism achieves secure fastening while minimizing device complexity.
3Force
If the hooking parts are designed to engage at an angle and pivot, then stress can be created in the object, but the manufacturing precision requirements increase
Solution Approach 1:
The fastening mechanism incorporates a dynamic pivoting motion that allows the elements to transition from an angled engagement position to a fastened position. This dynamic design accommodates variations in manufacturing precision by allowing the parts to self-align during the pivoting motion, while still enabling stress creation in the object.
Solution Approach 2:
The design allows for changes in the engagement parameters (angle, position) during the fastening process. The hooking parts are designed to engage at various angles and then pivot to the final position, providing tolerance for manufacturing variations while maintaining the ability to create stress in the object through the pivoting action.
4Reliability
If the second element is mounted to the object permanently, then loss of the element is prevented, but ease of release is reduced
Solution Approach 1:
The second element is pre-mounted to the object in a secure manner that prevents loss during normal use. The resilient hooking mechanism is designed to maintain strong engagement under normal conditions, yet allows for easy release when deliberate action is taken, such as pushing the elements apart or applying sufficient force to overcome the snap-action retention.

AI summary
The invention relates to a fastening device of locking press button type. It comprises a first element (1) which in use is present at a substrate and a second element (9) which, to fasten an object (10) to the substrate, can be releasably fastened to the first element by way of a to a snapping part (2) of the first element snapping snapping part (11) of it and wherein the elements (1, 9) remote from their snapping part (2, 11 respectively) have a hooking part (3, 8 respectively) such that the elements (1, 9) first have to be mutually engaged making a mutual angle by the hooking parts (3, 8) and then are pivoted onto each other to subsequently be fixed snapped to each other.
