Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If a component holder with relatively large mass is used to counteract process-related vibrations, then vibration stability is improved, but temperature control capability deteriorates due to sluggish heating and cooling behavior

Engineering Contradiction:

Improvevibration stabilityVSAvoidtemperature control capability

Core Design Contradiction:

Stability of the object's compositionVSTemperature

Solution Approach 1:

The component holder is divided into two distinct parts: a support structure with relatively large mass for vibration stability, and a component holding tool with smaller mass and integrated temperature control apparatus for responsive temperature management. This segmentation allows each part to optimize its function without compromising the other.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A temperature control apparatus acts as an intermediary between the support and the component holding tool. This intermediary enables independent temperature control of the component contact surface area, decoupling the thermal behavior from the mechanical support structure and allowing rapid temperature adjustments despite the support's large mass.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Stability of the object's composition

If the component holder has large mass to ensure stability, then mechanical stability is improved, but thermal response time deteriorates due to heat capacity

Engineering Contradiction:

Improvemechanical stabilityVSAvoidthermal response time

Core Design Contradiction:

Stability of the object's compositionVSSpeed

Solution Approach 1:

The system is segmented into a heavy support for mechanical stability and a lighter component holding tool for rapid thermal response. The temperature control apparatus is integrated with the holding tool rather than the support, enabling fast thermal adjustments independent of the support's thermal mass.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Temperature control is applied locally at the component contact surface area rather than to the entire component holder. This localized approach allows rapid temperature changes at the critical interface without requiring the entire heavy support structure to heat or cool, significantly improving thermal response time while maintaining mechanical stability.

Inventive Principle:

Principle #3Local quality

3Device complexity

If conventional component holders are used without temperature control, then device complexity is reduced, but temperature gradients occur during thermal assembly processes

Engineering Contradiction:

Improvedevice complexityVSAvoidtemperature uniformity

Core Design Contradiction:

Device complexityVSTemperature

Solution Approach 1:

A temperature control apparatus serves as an intermediary system between the support and the component holding tool. This apparatus actively compensates for temperature gradients by providing targeted heating or cooling at the component contact surface, ensuring temperature uniformity during thermal assembly processes like soldering or bonding.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system actively changes the temperature parameter at the component contact surface area in real-time during assembly processes. By dynamically adjusting temperature to maintain uniformity, the system prevents harmful temperature gradients that would otherwise occur due to the mass difference between the holder and the component.

Inventive Principle:

Principle #35Parameter changes
