Solution Overview

Problem

Existing dressing tools fail to securely hold diamonds, leading to instability and reduced effectiveness in machining processes.

Innovation Solution

The use of grooves in the dressing tool base body that extend from one side surface to the other, allowing diamonds to be fixed with solder on multiple sides, providing a large surface area for secure attachment and improved retention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If diamonds are bonded to a carrier on one side only, then the structure is simple, but the diamonds are not securely held leading to instability

Engineering Contradiction:
Improvediamond retentionVSAvoidgroove structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The invention transitions from bonding diamonds on a single surface to embedding them in grooves that extend through the base body thickness, utilizing the third dimension (depth) to create through-grooves that enable multi-sided soldering and significantly improve diamond retention

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

2Reliability

If diamonds are fixed with solder on multiple sides, then retention is improved, but the manufacturing process becomes more complex

Engineering Contradiction:
Improvediamond fixationVSAvoidsoldering process
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The grooves are pre-formed in the base body before the soldering process, providing predetermined pathways and surfaces for solder application. This preliminary groove formation simplifies the subsequent multi-sided soldering operation by establishing the exact geometry and location where solder should be applied

Inventive Principle:
Principle #10Preliminary action

3Area of stationary object

If grooves extend from one side surface to the other, then a large surface area is available for soldering, but the base body structure becomes more complex

Engineering Contradiction:
Improvesoldering surface areaVSAvoidbase body structure
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The base body is segmented with multiple grooves distributed across its surface, dividing the bonding function into discrete locations. Each groove provides a localized area for diamond embedding and soldering, collectively increasing the total soldering surface area while maintaining a manageable overall structure

Inventive Principle:
Principle #1Segmentation
