Solution Overview
Problem
Conventional fastening methods using screws are difficult to assemble and disassemble, making quick coupling and easy demounting challenging.
Innovation Solution
A fastening apparatus comprising a body with a movably disposed fastener and a resilient component that allows the fastener to protrude or insert, enabling quick coupling and easy demounting by interacting to effectuate limiting, stopping, or abutting actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screws are used to fix two objects together, then the coupling strength is improved, but the ease of assembly and disassembly deteriorates
Solution Approach 1:
The fastener is designed as a movable component that can rotate between locked and unlocked positions. The resilient component provides dynamic force to maintain engagement during normal use but allows easy release when needed, transforming the static screw connection into a dynamic system that adapts between strong coupling and easy separation states
Solution Approach 2:
The fastening system is divided into separate functional components: a body, a movable fastener, and a resilient component. This segmentation allows each component to perform its specific function independently - the body provides structure, the fastener provides engagement, and the resilient component provides maintaining force - while working together to achieve both strong coupling and easy disassembly
2Ease of operation
If a resilient component is added to enable quick coupling, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The resilient component is integrated within the body structure rather than being a separate external mechanism. The fastener combines multiple functions (engagement, rotation, and release) in a single component. This merging reduces the number of separate parts and simplifies the overall device structure while maintaining quick coupling capability
Solution Approach 2:
The resilient component automatically maintains fastener engagement during normal operation without requiring external intervention. The system is self-actuating during coupling - simply inserting the fastener triggers the resilient component to engage and lock the position, eliminating the need for complex control mechanisms or additional actuators

Implementation Method 1
a resilient component disposed at the body, the resilient component having an end abutting against the body and another end abutting against the fastener such that the resilient component allows the fastener to be protruded from or inserted into the body normally
Implementation Method 2
the fastener in rotation and the resilient component interact with each other to effectuate limiting-stopping, interfering-stopping or interfering-abutting

AI summary
A fastening apparatus includes a body; a fastener movably disposed at the body; and a resilient component disposed at the body, the resilient component having an end abutting against the body and another end abutting against the fastener such that the resilient component allows the fastener to be protruded from or inserted into the body normally, or the fastener in rotation and the resilient component interact with each other to effectuate limiting-stopping, interfering-stopping or interfering-abutting. The fastener enters the body disposed on the first object and compresses the resilient component. Then, the resilient component protrudes the fastener out of the body, thereby fastening the fastener to the second object quickly. Easy separation of the first and second objects entails moving the fastener into the body. A fastening method for the fastening apparatus is further introduced.
