Solution Overview

Problem

Existing tool cartridges require complex adjustability mechanisms involving clamping elements and intermediate pieces, making them cumbersome and difficult to fine-tune relative to the cartridge seat.

Innovation Solution

Incorporating adjusting screws with contact stamps and web guides to allow for stepless adjustment, using existing screwdrivers, and ensuring a defined position, with optional angled penetration for translational movement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If clamping elements or intermediate pieces are used for adjustment, then adjustability is achieved, but device complexity increases

Engineering Contradiction:
ImproveadjustabilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The invention extracts the adjustment function from complex clamping elements and intermediate pieces, concentrating it into a single adjusting screw with integrated features. The screw includes a contact stamp for positioning and a web guide for anti-twist functionality, eliminating the need for separate adjustment mechanisms while maintaining full adjustability capability

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention merges multiple functions into the adjusting screw: positioning (contact stamp), anti-twist (web guide), and adjustment (screw mechanism). This consolidation reduces the number of separate components needed for adjustment, directly reducing device complexity while preserving adaptability

Inventive Principle:
Principle #5Merging (Combining)

2Measurement precision

If multiple adjustment elements are provided, then adjustment precision is improved, but ease of operation deteriorates

Engineering Contradiction:
Improveadjustment precisionVSAvoidease of operation
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The adjusting screw is designed to perform multiple functions: fine adjustment of position, prevention of rotation (anti-twist via web guide), and providing a planar contact surface. This multi-functionality allows single-point adjustment to achieve comprehensive positioning control, maintaining precision while improving ease of operation

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The web guide automatically prevents rotation of the contact stamp during adjustment, and the contact stamp automatically provides a planar bearing surface. These self-service features eliminate the need for additional adjustment elements or operations, allowing precise adjustment through a single screw mechanism

Inventive Principle:
Principle #25Self-service
