Solution Overview

Problem

Existing sliding table assemblies require time-consuming design and installation of bearing rollers with specific tolerance values for smooth movement, and the rope-pulling type support structure is inconvenient for assembly and operation.

Innovation Solution

A sliding table assembly comprising a base unit, a sliding seat unit, an embracing unit with auxiliary sliding seats and roller sets, and a driving unit with a power driver and screw rod, where the auxiliary sliding seats are connected by rigid rods and supported by rollers on hardened rails to prevent sagging and facilitate smooth movement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If bearing rollers are designed with specific tolerance values for smooth movement, then movement smoothness is improved, but design time and manufacturing complexity increase

Engineering Contradiction:

Improvemovement smoothnessVSAvoiddesign time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent removes the complex bearing rollers from the system and replaces them with a simplified support structure consisting of auxiliary sliding seats mounted directly to the base unit. This extraction eliminates the need for precise tolerance design while maintaining smooth movement through the inherent sliding mechanism between the auxiliary sliding seats and base unit.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of using bearing rollers to support the screw rod, the patent inverts the support approach by having the auxiliary sliding seats support the screw rod directly. The screw rod passes through the auxiliary sliding seats, which are guided by the base unit, reversing the traditional support hierarchy and simplifying the overall structure.

Inventive Principle:

Principle #13The other way round (Inversion)

2Stability of the object's composition

If rope-pulling type support structure is used to prevent screw rod sagging, then screw rod stability is improved, but assembly convenience deteriorates

Engineering Contradiction:

Improvescrew rod stabilityVSAvoidassembly convenience

Core Design Contradiction:

Stability of the object's compositionVSEase of manufacture

Solution Approach 1:

The patent replaces the rope-pulling mechanical support system with a direct structural support system. The auxiliary sliding seats provide rigid support for the screw rod through their mounting to the base unit, eliminating the need for ropes and pulleys while improving assembly convenience through direct bolting or fixing mechanisms.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The support structure is segmented into independent auxiliary sliding seats that can be individually mounted to the base unit. Each auxiliary sliding seat independently supports a portion of the screw rod, allowing for modular assembly and easier installation compared to the integrated rope-pulling system.

Inventive Principle:

Principle #1Segmentation

3Reliability

If auxiliary sliding seats are mounted to base unit with rollers, then movement smoothness is improved, but device complexity increases

Engineering Contradiction:

Improvemovement smoothnessVSAvoidstructure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the auxiliary sliding seats with the roller mechanism into a single integrated component. The rollers are incorporated as part of the auxiliary sliding seat assembly, reducing the number of separate parts and simplifying the overall structure while maintaining smooth movement capability.

Inventive Principle:

Principle #5Merging (Combining)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The solution allows for easy assembly, reduced noise and vibration, increased service life of the screw rod, and maintains normal operation by preventing sagging, while simplifying the assembly process and reducing processing errors.

Implementation Method 1

The two roller sets (33) are respectively mounted to the auxiliary sliding seats (31). Each of the roller sets (33) has a plurality of rollers (332) to roll on the hardened rails (13).

Methodology Applied

Scientific EffectRolling: Roller

Implementation Method 2

The driving screw rod (42) is connected to the power driver (41) and threadedly coupled to the sliding seat unit (20). When the power driver drives the driving screw rod (42) to rotate with respect to the base, the sliding unit is driven by the driving screw rod to slide in the lengthwise direction

Methodology Applied

Scientific EffectScrew mechanism: Screw

AI summary

A sliding table assembly includes a sliding seat unit slidably mounted to a base unit. Two auxiliary sliding seats are slidably mounted to the base unit and disposed on two sides of the sliding seat unit. A connection member is connected between the auxiliary sliding seats. Two roller sets are respectively mounted to the auxiliary sliding seats. Each roller set has rollers to roll on the base unit. A driving screw rod is coupled to the sliding seat unit and embraced by the auxiliary seats. When the sliding unit is moved by the driving screw rod, it pushes the auxiliary sliding seats to slide together therewith.
