Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection devices for cable management systems and slide rail assemblies require improved designs to facilitate easy detachment with reduced effort, as current solutions are inefficient in this regard.
Innovation Solution
A connection device featuring a first fitting with a containing structure and a second fitting having a protrusion, along with a resilient member that generates an elastic force to unlock and lock the fittings, allowing for easy detachment and reattachment of the cable management device from the slide rail assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a connection device uses a resilient member with a blocking part to prevent detachment, then the stability and reliability of the connection is improved, but the ease of operation for detachment becomes more difficult
Solution Approach 1:
The blocking part is designed to dynamically change its position between a blocked state (preventing detachment) and an unblocked state (allowing detachment). When the resilient member is in its elastic state, the blocking part extends to block the protrusion. When the resilient member is deformed by applying force, the blocking part retracts to allow the protrusion to pass through, enabling easy detachment while maintaining connection stability during normal use.
Solution Approach 2:
The resilient member changes its physical state between elastic (blocking) and deformed (unblocking) conditions. By applying external force, the physical parameters of the resilient member change, causing the blocking part to transition from an extended blocking position to a retracted unblocking position. This parameter change allows the system to switch between stable connection and easy detachment states.
2Strength
If the containing structure has a narrow second portion to secure the protrusion, then the connection strength is improved, but the ease of insertion and detachment becomes more difficult
Solution Approach 1:
The system uses dynamic state changes of the resilient member to temporarily modify the effective width of the second portion. During insertion, the resilient member is in a deformed state, allowing the blocking part to be in an unblocked position, which effectively widens the passage and facilitates easy insertion. Once inserted, the resilient member returns to its elastic state, causing the blocking part to extend and effectively narrow the passage to secure the protrusion strongly.
Solution Approach 2:
The resilient member is pre-configured to be in a deformed state during the insertion process, which preliminarily opens the blocking part to create a wider passage. This preliminary action reduces the insertion force required. After insertion is complete, the resilient member naturally returns to its elastic state, automatically engaging the blocking part to secure the connection without requiring additional fastening actions.

AI summary
A connection device (26, 28) for a cable management device (24) and a slide rail assembly (22) is disclosed. The slide rail assembly (22) includes a first rail (30) and a second rail (32), and the rails (30, 32) are displaceable with respect to each other. The cable management device (24) includes a first arm (36) and a second arm (38). The first arm (36) and the second arm (38) are movable with respect to each other and respectively coupled to the first rail (30) and the second rail (32) by two connection devices (26, 28). At least one of the connection devices (26, 28) includes a first fitting (46, 47), a second fitting (48, 49) and a resilient member (50, 51). When the first fitting (46, 47) is mounted to the second fitting (48, 49), a part (50b) of the resilient member (50, 51) is configured to prevent the first (46, 47) and second fittings (48, 49) from being detached from each other.
