Solution Overview

Problem

Existing slide rail mechanisms lack versatility and ease of use in accommodating diverse market requirements, particularly in moving and positioning components with minimal effort.

Innovation Solution

A slide rail assembly with a handle and supporting feature that allows the second rail to move between predetermined positions relative to the first rail by contacting the supporting feature, facilitating easy movement with reduced effort.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a traditional slide rail mechanism is used, then the structure is simple, but the ease of operation is poor and requires significant effort to move the second rail

Engineering Contradiction:

Improveease of operationVSAvoiddevice complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

A handle is introduced as an intermediary tool between the user and the second rail. The handle engages with the supporting feature on the second rail, allowing the user to apply force through the handle rather than directly to the rail, thereby reducing the effort required to move the heavy second rail while maintaining structural simplicity

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The operation of moving the second rail is segmented into two parts: the handle (operating mechanism) and the second rail (load-bearing component). This segmentation allows the operating mechanism to be optimized for ease of use while the second rail maintains its structural integrity and load-bearing capacity

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If a fixed slide rail mechanism is used, then the structure is stable, but the adaptability to diverse market requirements is limited

Engineering Contradiction:

ImproveadaptabilityVSAvoidstability

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The system transitions from a completely fixed structure to a dynamic configuration where the second rail can be selectively positioned between a retracted position and an extended position. The handle and supporting feature enable controlled movement, providing adaptability for different operational scenarios while maintaining stability when positioned

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The slide rail assembly is designed to serve multiple functions: it can remain in a retracted position for compact storage, extend to a working position for operation, and be easily repositioned using the handle mechanism. This multi-functionality enhances adaptability to diverse market requirements without compromising the basic structural stability

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A slide rail assembly includes a first rail, a supporting feature, a second rail and a handle. The supporting feature is arranged on one of the first rail and the second rail. The handle is movably mounted on the other one of the first rail and the second rail. When the handle is moved from a first operating position to a second operating position, the handle is configured to contact the supporting feature in order to drive the second rail to move from a predetermined position along a direction.
