Solution Overview

Problem

Existing electronic modules for tools lack effective vibration damping and heat dissipation, leading to potential damage and inefficient operation, while also being difficult to securely attach to a variety of tools without requiring tools for detachment.

Innovation Solution

An electronic module with a damping unit that forms the tool interface, providing at least 50% damping of vibrations and heat dissipation, allowing relative movement, and featuring a holding device for secure, tool-free attachment and detachment using a bayonet fitting or clamping mechanism.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the electronic device is directly mounted on the tool without damping units, then the device can detect tool parameters, but the device is damaged by vibrations and heat from the tool

Engineering Contradiction:

Improvedevice protectionVSAvoidvibration and heat exposure

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The damping unit acts as an intermediary element positioned between the tool and the electronic device. It provides mechanical isolation through vibration-damping material, reducing the transmission of harmful vibrations and heat from the tool to the electronic device while still allowing the device to function and detect tool parameters

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The damping unit is pre-installed on the tool interface before the electronic device is mounted. This beforehand cushioning creates a protective layer that absorbs and dissipates vibration energy and heat, preventing direct transmission to the electronic device and protecting it from damage before exposure occurs

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

2Stability of the object's composition

If a secure mounting mechanism is used to attach the electronic device to the tool, then the device remains stable during operation, but the attachment and detachment process becomes complex and requires tools

Engineering Contradiction:

Improvemounting stabilityVSAvoidattachment and detachment convenience

Core Design Contradiction:

Stability of the object's compositionVSEase of operation

Solution Approach 1:

The holding device incorporates a dynamic clamping mechanism with movable clamping arms that can transition between open and closed positions. This allows the device to be quickly attached by simply closing the arms (tool-free operation) while maintaining secure, stable mounting during operation, and easily detached by opening the arms

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The clamping mechanism is designed to be operated manually without requiring additional tools. The user can directly open and close the clamping arms to attach and detach the electronic device, making the system self-service capable and eliminating the need for external tooling

Inventive Principle:

Principle #25Self-service

3Reliability

If the damping unit forms the tool interface, then vibration damping and heat dissipation are improved, but the contact surface area for parameter detection may be reduced

Engineering Contradiction:

Improvevibration damping efficiencyVSAvoidcontact surface area

Core Design Contradiction:

ReliabilityVSArea of stationary object

Solution Approach 1:

The damping unit is designed with non-uniform properties: the outer surface that contacts the tool is made of vibration-damping material to maximize damping efficiency, while inner surfaces or specific zones maintain sufficient contact area for parameter detection. This local differentiation allows the same component to fulfill both damping and detection requirements

Inventive Principle:

Principle #3Local quality
