Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If a pointer-type angle measuring device is used in low light environment, then angle measurement function is provided, but the pointer cannot be seen clearly due to lack of lighting

Engineering Contradiction:

Improvepointer illuminationVSAvoiddevice structure

Core Design Contradiction:

Illumination intensityVSDevice complexity

Solution Approach 1:

The patent combines the lighting function with the pointer structure by integrating an LED light source and power receiving coil into the pointer body. The pointer serves dual purposes: indicating angle measurements and providing its own illumination, eliminating the need for separate lighting devices and reducing overall system complexity.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent replaces traditional wired power supply with wireless electromagnetic induction power transmission. The power receiving coil in the pointer receives energy wirelessly from the base station's transmitting coil, eliminating mechanical connections and making the lighting system more convenient and reliable.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If wireless power supply is added to the pointer for lighting, then lighting function is enabled, but the device structure becomes more complex

Engineering Contradiction:

Improvelighting operation convenienceVSAvoidcircuit structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The base station serves multiple functions: it acts as both the angle measurement reference point and the wireless power transmitter. The integrating circuit board combines power transmission and control functions in one component, reducing the number of separate parts and simplifying the overall system.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Illumination intensity

If the pointer head is made transparent for lighting, then light transmission is improved, but the structural strength is reduced

Engineering Contradiction:

Improvelight transmissionVSAvoidpointer head strength

Core Design Contradiction:

Illumination intensityVSStrength

Solution Approach 1:

The patent uses transparent acrylic material for the pointer head that provides both optical transparency for light transmission and sufficient mechanical strength. This composite material approach allows the pointer head to serve both as a light guide and a structurally sound component.

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The patent embeds the LED light source and power receiving coil within the hollow interior of the pointer head. This nested arrangement allows the transparent pointer head to function as both the structural element and the light guide, while housing the electronic components inside, thus maintaining strength while enabling lighting.

Inventive Principle:

Principle #7Nested doll (Nesting)
