Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If a light assembly is integrated into the tool accessory holder, then visibility of the workpiece is improved, but device complexity increases

Engineering Contradiction:

Improvevisibility of workpieceVSAvoidcomplexity of tool accessory holder

Core Design Contradiction:

Illumination intensityVSDevice complexity

Solution Approach 1:

The light assembly is integrated into the tool accessory holder housing, combining illumination functionality with the existing tool structure. This merging approach improves workpiece visibility while minimizing the increase in overall device complexity by utilizing the existing housing space rather than adding a completely separate illumination system.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The insert serves multiple functions: it acts as a vibration damping member, provides structural support for the light assembly, and contributes to the overall housing structure. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity while achieving the illumination goal.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If a vibration damping member is added to protect electronic components, then reliability is improved, but device complexity increases

Engineering Contradiction:

Improveprotection of electronic componentsVSAvoidcomplexity of tool accessory holder

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The vibration damping function is integrated into the existing insert structure rather than being implemented as a separate component. This combining approach protects electronic components from vibrations while avoiding the need for additional separate damping elements, thus improving reliability with minimal impact on device complexity.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The insert is designed to serve multiple purposes: it provides vibration damping protection for electronic components, supports the light assembly, and contributes to the structural integrity of the housing. This multi-functionality ensures component protection without requiring additional dedicated damping components.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If an insert is used to dampen vibrations, then reliability is improved, but manufacturing complexity increases

Engineering Contradiction:

Improvevibration damping between input shaft and housingVSAvoidmanufacturing of insert

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The insert is formed from a composite material that inherently provides vibration damping properties. This material selection achieves the desired vibration damping effect for improved reliability while maintaining relative ease of manufacture, as the damping capability is inherent to the material rather than requiring complex multi-step manufacturing processes or assembly of multiple components.

Inventive Principle:

Principle #40Composite materials
