Solution Overview

Problem

Existing slider arrangements require extensive space for maintenance and repair due to the need to loosen retaining clips from the side, making it difficult to perform maintenance and repair work, especially when multiple arrangements are closely spaced.

Innovation Solution

The guide and retaining clip are designed to be connected and released in the sliding direction relative to the slider carrier, allowing for lateral detachment parallel to the sliding direction, eliminating the need for lateral space and enabling closer arrangement of multiple slider assemblies.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the guide and retaining clip is firmly connected to the slide carrier from the side, then the connection is secure and reliable, but the overall length of the guide and retaining clip increases and lateral space is required for maintenance

Engineering Contradiction:
Improveconnection reliabilityVSAvoidoverall length of guide and retaining clip
Core Design Contradiction:
ReliabilityVSLength of stationary object

Solution Approach 1:

The patent inverts the conventional connection approach by connecting the guide and retaining clip to the slide in the sliding direction rather than from the side. This reversal allows the connection to be made in-line with the motion path, eliminating the need for lateral access and reducing the overall length requirement while maintaining secure connection.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The patent changes the dimensional approach by transitioning from lateral (transverse) connection to longitudinal (sliding direction) connection. This dimensional shift allows the guide and retaining clip to be connected along the direction of motion rather than perpendicular to it, solving both the length and maintenance access issues.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Reliability

If the guide and retaining clip is firmly connected from the side, then the connection is secure, but lateral space is required for loosening and tightening during maintenance

Engineering Contradiction:
Improveconnection securityVSAvoidmaintenance accessibility
Core Design Contradiction:
ReliabilityVSEase of repair

Solution Approach 1:

The patent inverts the conventional maintenance approach by making the connection and disconnection possible in the sliding direction rather than requiring lateral access. This allows maintenance personnel to loosen and tighten the guide and retaining clip from the end of the slide carrier, eliminating the need for lateral space and greatly improving maintenance accessibility.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The patent enables self-service maintenance by designing the connection system so that the guide and retaining clip can be easily connected and disconnected in the sliding direction without requiring special tools or lateral access. The wedge-shaped design allows the components to be self-retaining during operation but easily removable when needed for maintenance.

Inventive Principle:
Principle #25Self-service

3Area of stationary object

If multiple slide arrangements are positioned next to one another, then space utilization is improved, but maintenance becomes difficult due to limited lateral space

Engineering Contradiction:
Improvespace utilizationVSAvoidmaintenance difficulty
Core Design Contradiction:
Area of stationary objectVSEase of repair

Solution Approach 1:

The patent resolves the maintenance difficulty in compact arrangements by inverting the access direction from lateral to longitudinal. Since the guide and retaining clip are connected in the sliding direction, maintenance can be performed from the end of each slide carrier without requiring lateral space, allowing multiple arrangements to be positioned closely together while maintaining easy accessibility for maintenance.

Inventive Principle:
Principle #13The other way round (Inversion)

4Manufacturing precision

If the guide and retaining clip is made extremely long to ensure precise guiding over entire travel, then low-backlash operation is achieved, but manufacturing and assembly cost increases

Engineering Contradiction:
Improveguiding precisionVSAvoidmanufacturing and assembly cost
Core Design Contradiction:
Manufacturing precisionVSEase of manufacture

Solution Approach 1:

The patent reduces the required length of the guide and retaining clip by inverting the connection approach. By connecting in the sliding direction rather than from the side, the guiding function is achieved over a shorter length, reducing manufacturing complexity and assembly cost while maintaining the necessary guiding precision through the wedge-shaped design and proper alignment.

Inventive Principle:
Principle #13The other way round (Inversion)
