Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If an electronic unit with display, control unit and power source is integrated into the boring head, then digital indication of radial displacement and status data is achieved, but the construction becomes complicated and expensive

Engineering Contradiction:

Improvedigital indication of radial displacementVSAvoidconstruction complexity

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The patent combines the display, control unit, and power source into a single integrated electronic unit that is mounted on the boring head. This merging of multiple components into one unified module achieves digital indication functionality while managing construction complexity through integrated design rather than separate component installation.

Inventive Principle:

Principle #5Merging (Combining)

2Loss of information

If multiple electric components and lines are provided in the boring head, then digital display functionality is achieved, but the risk of failure increases due to centrifugal forces and exposure to dirt and cooling liquid

Engineering Contradiction:

Improvestatus data displayVSAvoidcomponent failure risk

Core Design Contradiction:

Loss of informationVSReliability

Solution Approach 1:

The electronic unit is enclosed in a housing that seals the electric components and lines from the external environment. This protective enclosure acts as a barrier against dirt particles and cooling liquid, preventing contamination while allowing the digital display functionality to operate reliably under high rotational velocities and centrifugal forces.

Inventive Principle:

Principle #30Flexible shells and thin films

3Loss of information

If electronic components are integrated into the limited space of the boring head, then compact digital indication is achieved, but the available space for component placement is constrained

Engineering Contradiction:

Improveintegrated digital displayVSAvoidspace for electronic components

Core Design Contradiction:

Loss of informationVSArea of stationary object

Solution Approach 1:

The electronic unit with its display, control unit, and power source is designed as a compact nested assembly that fits within the limited space of the boring head. The components are arranged in a space-efficient configuration where smaller components are positioned within or adjacent to larger ones, maximizing the use of available space while maintaining all required functionalities.

Inventive Principle:

Principle #7Nested doll (Nesting)

4Area of stationary object

If the electronic unit is designed as a compact subassembly, then space efficiency is improved, but the ease of maintenance and replacement is reduced

Engineering Contradiction:

Improvespace efficiencyVSAvoidmaintenance accessibility

Core Design Contradiction:

Area of stationary objectVSEase of repair

Solution Approach 1:

The electronic unit is designed as a separate, modular subassembly that can be easily detached from the main boring head body. This segmentation allows the electronic components to be maintained or replaced as a single unit without disassembling the entire boring head, combining space efficiency with ease of maintenance through modular design.

Inventive Principle:

Principle #1Segmentation
