Solution Overview

Problem

Existing slide positioning devices for film application processes require complex and costly active mechanisms to achieve multiple precise positions, as traditional clamp devices are non-adjustable and require threaded rods or gear-shaft combinations for movement.

Innovation Solution

A slide positioning device with a main body, slide member, rough positioning member, and fine positioning assembly, featuring positioning holes and grooves, a latch member, and a biasing member, allowing for precise alignment and holding of the slide member in multiple positions using a simplified structure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If an active mechanism such as threaded rod and nut or gear-shaft combination is used to move the clamp device for multiple positions, then the workpiece can be processed at multiple positions, but the structure becomes excessively complex and cost increases

Engineering Contradiction:

Improvemultiple position processing capabilityVSAvoidstructure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The positioning system is segmented into discrete positioning holes along the axis and corresponding positioning protrusions on the slide member, allowing independent position selection without complex continuous adjustment mechanisms. Each positioning hole represents a discrete position that can be independently selected.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The invention extracts the essential positioning function from complex active mechanisms. By using a simple slide member with positioning protrusions that engage with positioning holes, the patent removes the need for threaded rods, nuts, or gear-shaft combinations while retaining multiple position capability.

Inventive Principle:

Principle #2Taking out (Extraction)

2Adaptability or versatility

If traditional clamp devices are used with fixed positions, then the structure remains simple, but the workpiece cannot be processed at multiple positions efficiently

Engineering Contradiction:

Improvemultiple position processing capabilityVSAvoidmanufacturing simplicity

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The slide member is designed to be movable along the axis relative to the main body, transforming the fixed-position clamp device into a dynamic positioning system. The slide member can be moved to different positions and locked using the positioning holes and protrusions mechanism.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

Multiple positioning holes are created as copies along the axis, each representing a valid position. This allows the slide member to be positioned at any of these copied locations without requiring complex adjustment mechanisms for each position.

Inventive Principle:

Principle #26Copying

3Manufacturing precision

If positioning holes and grooves with latch member are used, then dimensional accuracy and positioning precision are improved, but the device complexity increases slightly

Engineering Contradiction:

Improvepositioning precisionVSAvoidpositioning mechanism complexity

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The invention replaces complex mechanical adjustment mechanisms with a geometric interlocking system. The positioning protrusion on the slide member fits into positioning holes in the main body, and the latch member engages with positioning grooves to lock the position, eliminating the need for threaded rods, nuts, or gear-shaft combinations.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The positioning system is self-aligning and self-locking. The positioning protrusion automatically aligns with the positioning hole, and the latch member with the biasing member automatically engages with the positioning groove to lock the slide member in place, requiring no additional adjustment or control mechanisms.

Inventive Principle:

Principle #25Self-service

AI summary

A slide positioning device includes a main body and a slide member slidable relative to the main body along a axis. The main body defines a plurality of positioning holes along the axis, and the slide member defines a plurality of positioning grooves along the axis. A rough positioning member is selectively received in one positioning hole to roughly position the sliding member. A fine positioning assembly includes a latch member selectively received in one positioning groove to precisely position the sliding member. A biasing member biases the latch member toward the sliding member.
