Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the battery capacity is increased to improve performance, then the battery size and mass increase, but the vibration resonance increases leading to distorted measurement results

Engineering Contradiction:
Improvebattery capacityVSAvoidmeasurement accuracy
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

A damping element is introduced as an intermediary component between the battery and the measurement device. This damping element absorbs vibrations generated by the battery, preventing them from reaching the measurement sensors. The damping element acts as a mediator that isolates the harmful vibrational effects while allowing the larger capacity battery to be used, thus resolving the contradiction between battery capacity and measurement precision.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If the battery mass is reduced to minimize vibration resonance, then the battery capacity is limited, but the overall performance of the vibration measurement device is reduced

Engineering Contradiction:
Improvevibration resonanceVSAvoiddevice performance
Core Design Contradiction:
Object-affected harmful factorsVSProductivity

Solution Approach 1:

The damping element serves as a mediator that allows the system to use a larger mass battery without suffering from increased vibration resonance. By placing the damping element between the battery and the measurement device, the harmful vibrations are absorbed before they can affect the measurement accuracy, thus enabling larger capacity batteries to be used while maintaining measurement quality.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Stability of the object's composition

If mechanical locking features are used to secure the battery, then the battery is held in place, but tolerances and vibrational resonances of the internal structure are not eliminated

Engineering Contradiction:
Improvebattery positioningVSAvoidvibration resonance
Core Design Contradiction:
Stability of the object's compositionVSMeasurement precision

Solution Approach 1:

The damping element is introduced as an intermediary between the battery and the measurement device that goes beyond simple mechanical locking. While mechanical features provide positioning stability, the damping element additionally absorbs vibrational energy and eliminates resonances that mechanical locking alone cannot address, thus improving measurement precision while maintaining battery stability.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Object-affected harmful factors

If allowable deviation in battery dimensions is reduced to minimize vibration resonance, then the vibration resonance is reduced, but the implementation cost increases

Engineering Contradiction:
Improvevibration resonanceVSAvoidmanufacturing cost
Core Design Contradiction:
Object-affected harmful factorsVSEase of manufacture

Solution Approach 1:

Instead of requiring tight manufacturing tolerances for the battery and internal structure, a damping element is introduced as a cost-effective intermediary solution. The damping element compensates for dimensional variations and tolerances in the battery and internal structure by absorbing vibrations, thereby achieving vibration resonance reduction without the need for expensive precision manufacturing.

Inventive Principle:
Principle #24Intermediary (Mediator)
