Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connection structures for circuit boards or plates to chassis/motherboards are not slidable and lack vibration-proof capabilities, failing to meet modern installation requirements that demand both sliding and secure, vibration-absorbing connections.
Innovation Solution
A vibration-proof fastener post structure with a body portion fixedly connected to one object and a slidably connected end that engages with a slideway hole on another object, utilizing an elastic element to secure the connection in a vibration-proof manner, allowing for sliding and secure fastening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional fixing element (screw or rivet) is used to connect a circuit board to a chassis, then the circuit board is firmly fixed, but the circuit board cannot be slid to a predetermined position
Solution Approach 1:
The fastening element transitions from a static fixed state to a dynamic state where it can slide along the chassis. The elastic element enables the fastening element to move dynamically during installation and operation, allowing sliding to a predetermined position while maintaining connection stability through the elastic restoring force.
Solution Approach 2:
The connection system is divided into separate functional components: a fastening element for sliding and fastening, and an elastic element for providing restoring force. This segmentation allows each component to perform its specific function independently, enabling both sliding capability and connection stability.
2Reliability
If a conventional fixing element is used to connect a circuit board to a chassis, then the connection is simple and firm, but the connection lacks vibration-proof or shock-absorbing capability
Solution Approach 1:
The elastic element is pre-installed on the fastening element to provide cushioning against vibrations and shocks before they occur. This beforehand cushioning protects the circuit board connection from harmful vibrations and shocks during operation, enhancing reliability without requiring complex active vibration control systems.
Solution Approach 2:
The elastic element acts as an intermediary between the fastening element and the circuit board, absorbing and dampening vibrations and shocks before they reach the connection. This intermediary component protects the connection while keeping the overall structure relatively simple.
3Adaptability or versatility
If an elastic element is added to enable sliding and vibration-proof fastening, then the connection gains sliding capability and vibration resistance, but the device complexity increases
Solution Approach 1:
The elastic element and fastening element are merged into a single integrated assembly where the elastic element is mounted directly on the fastening element. This merging reduces the number of separate components and simplifies installation while providing both sliding capability and vibration-proof fastening function.
Solution Approach 2:
The fastening element with the integrated elastic element serves multiple functions: it enables sliding to a predetermined position, provides firm fastening at the target position, and offers vibration-proof capability. This multi-functionality reduces the need for separate components for each function, thereby limiting the increase in device complexity.

AI summary
A vibration-proof fastener post structure includes a body portion having a first end integrally formed with or assembled to a first object; a fastening head portion movably mounted to a second end of the body portion and having a neck portion, which is movably disposed in the body portion for moving in a slideway hole of a second object; and an elastic element movably fitted around the neck portion to push against the body portion. The fastening head portion and the body portion are configured for engaging with and fastening to the slideway hole of the second object. The second object is slidably relative to the neck portion. When the second object is slid to a predetermined position, the fastening head portion and the elastic element, the body portion or the pushing member will engage with the slideway hole of the second object to achieve a vibration-proof fastening effect.
