1Object-affected harmful factors

If a damping unit is added to damp vibrations, then vibration damping is improved, but device complexity increases

Engineering Contradiction:

Improvevibration dampingVSAvoiddevice complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The damping unit is integrated into the holding device structure, merging the damping function with the existing holding mechanism. The damping element is positioned between the electronic device and the holding device housing, combining structural support with vibration damping in a single integrated component arrangement.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The holding device is designed to perform multiple functions: it holds the electronic device securely on the insert tool, provides vibration damping through the integrated damping unit, and maintains electrical contacts. This multi-functionality reduces the need for separate components and simplifies the overall device structure.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Object-affected harmful factors

If the damping unit constitutes the insert-tool interface, then vibration damping is improved, but heat dissipation may be affected

Engineering Contradiction:

Improvevibration dampingVSAvoidheat dissipation

Core Design Contradiction:

Object-affected harmful factorsVSTemperature

Solution Approach 1:

The damping element is positioned specifically between the electronic device and the holding device housing, providing localized vibration damping where needed. The holding device maintains direct contact with the insert tool at the interface, preserving the thermal conduction path from the insert tool to the holding device housing, while the damping element provides targeted vibration protection without interfering with the overall heat dissipation pathway.

Inventive Principle:

3Ease of operation

If the holding device is designed for releasable attachment, then ease of operation is improved, but reliability of attachment may be reduced

Engineering Contradiction:

Improveease of attachment and detachmentVSAvoidattachment reliability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The holding device features a curved outer surface that complements the curved interface of the insert tool, creating a secure fit through geometric interlocking. This curved geometry provides reliable attachment while maintaining ease of operation through simple insertion and removal motions.

Inventive Principle:

Principle #14Spheroidality (Curvature)

Solution Approach 2:

The damping element is made of a material with specific mechanical properties that provide both compliance for easy attachment and secure holding force for reliable operation. The material characteristics enable the damping element to deform during attachment and then maintain a stable, secure connection during use.
