Elastic Projections on Fastener Magazine Strip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastener magazine strips require special guide grooves for projections, which can impede the setting operation and strip transport, and do not allow for an additional function without compromising the process.
Innovation Solution
The projections are designed to be bendable and elastically flexible, allowing them to fold into recesses on the carrier segments during a setting operation, eliminating the need for separate guide grooves and enabling an additional function without impeding the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If projections are arranged on carrier segments to enable additional function (counter-slider contact), then the additional function is achieved, but special guide grooves must be provided in the bolt guide which complicate the device and may impede the setting operation
Solution Approach 1:
The projections are designed to be elastically deformable, allowing them to dynamically change their position during the setting operation. They extend radially outward during transport to enable counter-slider contact, but can be deformed radially inward to pass through the bolt guide without obstruction, thus eliminating the need for complex guide grooves
Solution Approach 2:
The radial position parameter of the projections is changed during operation. During transport, the projections maintain their extended radial position for guidance and contact functions. During the setting operation, the projections are deformed to a retracted radial position to clear the bolt guide path, eliminating the need for specialized guide grooves
2Reliability
If projections are made rigid to ensure reliable guidance on guide surfaces, then guidance reliability is improved, but the projections cannot fold away during setting operation, impeding the process
Solution Approach 1:
The projections transition from a rigid state during transport (providing reliable guidance) to a flexible/deformed state during the setting operation (allowing them to fold away). This dynamic adaptability resolves the contradiction between needing rigidity for guidance and flexibility for the setting operation
Solution Approach 2:
The projections are constructed with flexible material properties, allowing them to maintain shape for reliable guidance during transport, yet deform when needed to clear the bolt guide during the setting operation. This flexibility enables both reliable guidance and unimpeded setting operation
3Adaptability or versatility
If projections extend radially outward to provide contact surfaces for transport rake and counter-slider, then additional functions are enabled, but the projections may obstruct the bolt guide during setting operation
Solution Approach 1:
The radial extension of the projections is dynamically controlled: extended during transport to provide contact surfaces for the transport rake and counter-slider, and retracted/deformed during the setting operation to eliminate obstruction in the bolt guide area
Solution Approach 2:
The projections are positioned in advance to extend radially outward for transport and guidance functions. Before the setting operation begins, the projections are deformed to a retracted position, preliminarily removing the potential obstruction before it can interfere with the setting process

Function Achieved in This Case
This design ensures smooth operation and transport of the fastener magazine strip by allowing projections to fold away from the bolt guide, preventing obstruction and enabling reliable guidance and additional functions like counter-slide contact, thus enhancing the functionality and efficiency of the fastener magazine strip.

AI summary
The present invention relates to a fastener magazine strip (10) with a carrier strip (11) made of plastic, formed by several interconnected carrier segments (12) and extending along a longitudinal axis (A). The carrier segments (12) have at least one guide section (20) with a guide diameter (D) and with through-openings (13) in each of which a fastener (30) is mounted. Projections (14) extend from the carrier strip (11) on both sides of a plane (E) defined by the carrier strip (11). These projections extend from their point of attachment (15) to the carrier strip (11) over a length (L) to their free end (16) and have a first width (B1) perpendicular to this length (L). The projections (14) extend radially (with respect to the longitudinal axis (A)) beyond the guide diameter (D).The projections (14) are designed to be elastically bendable in at least one direction transverse to their longitudinal extent.
