Multi-Part Insulation Anchor Snap Fastener Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-part insulating material anchors face challenges in achieving a reliable and cost-effective snap-in closure between the holding and anchor parts, which affects their manufacturing efficiency and tensile load resistance.
Innovation Solution
The design incorporates a locking lug that projects radially into the through-channel to prevent axial movement of the anchor part, forming a reliable latching mechanism with a stop element, allowing for self-centering and high tensile load resistance, and utilizing a snap-in closure with axially offset bodies for protection against external influences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a snap-in closure is used to connect the holding part and anchor part, then the device complexity is reduced and manufacturing efficiency is improved, but the reliability of the connection under tensile loads deteriorates
Solution Approach 1:
The collar of the anchor part is inserted into the through-channel of the holding part, with the stop element and locking lug nested within the through-channel to form a compact, integrated connection structure that reduces overall complexity while maintaining strength
Solution Approach 2:
The locking lug is designed to engage dynamically with the collar during insertion, automatically locking into place to prevent axial movement. This dynamic engagement ensures reliable connection under tensile loads without requiring complex additional components
2Adaptability or versatility
If a telescopic function is provided with adjustable length, then the adaptability is improved, but the device complexity increases due to additional locking mechanisms
Solution Approach 1:
The anchor is divided into separable holding part and anchor part that can be inserted and locked together, allowing length adjustment while using a simple snap-in closure rather than complex telescopic mechanisms
Solution Approach 2:
The locking lug and stop element automatically engage to lock the collar in position during insertion, providing self-locking functionality that enables telescopic adjustment without requiring additional active locking mechanisms
3Ease of manufacture
If the anchor part is inserted from the rear end of the holding part, then the ease of manufacture is improved through self-centering, but the axial movement control becomes more difficult
Solution Approach 1:
The stop element is pre-positioned within the through-channel to engage with the collar, establishing axial movement limits before the locking lug engages. This preliminary positioning control facilitates self-centering during insertion while preventing excessive axial movement
