Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a robot arm is used to fix and rotate the color meter for measuring display devices at different viewing angles, then measurement versatility is improved, but device complexity and space occupation increase

Engineering Contradiction:

Improvemeasurement angle adjustmentVSAvoidrobot arm system

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The measurement system is segmented into a stationary color meter and a separate rotatable abutting member. The abutting member can be independently rotated to different viewing angles while the color meter remains fixed, eliminating the need for a complex robot arm system while maintaining measurement versatility.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The abutting member serves as an intermediary between the color meter and the display device. It provides the rotational capability and angle adjustment function, allowing the color meter to measure at different viewing angles without requiring the color meter itself to be mounted on a complex positioning system.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Extent of automation

If the color meter is fixed on a robot arm for automatic measurement, then measurement automation is improved, but space occupation increases

Engineering Contradiction:

Improveautomatic measurementVSAvoidspace occupation

Core Design Contradiction:

Extent of automationVSArea of stationary object

Solution Approach 1:

The system separates the automation function (controlled rotation of abutting member) from the measurement function (color meter). The abutting member's rotation can be automatically controlled while the color meter remains stationary, reducing the space required compared to mounting the entire measurement system on a robot arm.

Inventive Principle:

Principle #1Segmentation

3Ease of operation

If the color meter faces the display device perpendicularly for traditional measurement, then measurement simplicity is improved, but adaptability to different viewing angles deteriorates

Engineering Contradiction:

Improvemeasurement simplicityVSAvoidviewing angle measurement

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The abutting member is designed to be rotatable, allowing the measurement system to dynamically adjust to different viewing angles. The color meter itself remains stationary and simple to operate, while the abutting member's rotation provides the adaptability needed for measuring at various angles, combining simplicity with versatility.

Inventive Principle:

Principle #15Dynamics

4Measurement precision

If the measurement program is re-configured for each viewing angle, then measurement precision is improved, but loss of time increases

Engineering Contradiction:

Improveoptical data accuracyVSAvoidreconfiguration time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The abutting member is pre-configured with markings or reference features that indicate different viewing angles. This allows the operator to quickly set the desired angle without reconfiguring the entire measurement program, reducing the time lost while maintaining measurement precision through the structured angle reference system.

Inventive Principle:

Principle #10Preliminary action

AI summary

An optical measurement apparatus includes a color analyzing device and an abutting member. The color analyzing device includes a light collecting portion, a body and a connecting portion. The light collecting portion is configured to face to a device under test (DUT) and collect a light emitted from the DUT. The body is configured to measure and analyze the light. The connecting portion connects between the body and the light collecting portion along an axis. The abutting member is tubular and extends along the axis. The abutting member has a first rim and a second rim opposite to the first rim along the axis. The connecting portion penetrates through the first rim and connects with an inner wall of the abutting member. The second rim defines a first abutting surface inclined by a measurement angle relative to the axis and configured to abut against the DUT.
