Solution Overview

Problem

Conventional pin and stop block implementations on gridded tables lack secure attachment and precision in positioning, leading to unwanted movement and imprecise alignment of workpieces during application processes.

Innovation Solution

Positionable block assemblies featuring a block body with a tooth surface and a plate member with a matching tooth surface, allowing for interlocking and multiple positional engagement, along with pin slots and apertures for secure attachment to a grid surface, enabling precise and repositionable alignment of workpieces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional pin and stop block implementations are used on gridded tables, then the setup is simple and easy to manufacture, but the attachment is not secure and positioning precision is poor

Engineering Contradiction:
Improveattachment securityVSAvoidblock assembly structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The block assembly is divided into separate components: a block body with internal cavity, a plate member with engagement features, and pin slots. This segmentation allows each component to be optimized independently while working together to provide secure attachment and precise positioning.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The plate member is positioned within the internal cavity of the block body, creating a nested structure. The engagement features of the plate member interact with corresponding features in the block body to provide secure mechanical interlocking and stable attachment to the gridded table.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Measurement precision

If conventional pin and stop block implementations are used, then the device is simple in structure, but the positioning precision and alignment accuracy are insufficient

Engineering Contradiction:
Improvepositioning accuracyVSAvoidblock assembly structure
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The engagement features are designed with specific geometric characteristics including angled surfaces and complementary shapes that provide precise mechanical interlocking. These localized geometric features ensure accurate positioning and alignment while maintaining overall structural simplicity.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The engagement features are designed to self-align and self-lock when the block assembly is attached to the gridded table. The angled surfaces and complementary geometries automatically guide the components into their correct positions without requiring additional alignment tools or complex adjustment mechanisms.

Inventive Principle:
Principle #25Self-service

3Stability of the object's composition

If conventional pin and stop block implementations are used, then the setup process is quick, but the workpiece alignment stability changes during work application

Engineering Contradiction:
Improveworkpiece alignment stabilityVSAvoidblock assembly structure
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The engagement features are pre-designed with specific geometries that create inherent mechanical interlocking and resistance to movement. This preliminary design ensures that once the block assembly is attached to the gridded table, the workpiece alignment remains stable throughout the work application process without requiring continuous adjustment or reinforcement.

Inventive Principle:
Principle #10Preliminary action

AI summary

Positionable block assemblies are described. Example block assemblies include a block body with a tooth surface and a plate member with a tooth surface. The tooth surfaces of the plate member and the block body are engageable to interlock the plate member with the block body. Further, the block body is engageable with the plate member at multiple different positions to enable precise positioning of a positionable block assembly to achieve a variety of different working scenarios.
