Solution Overview

Problem

Existing grinding machine housing devices lack a compact and ergonomic design for energy storage interfaces, which complicates the arrangement of energy storage devices and particle collecting containers, and does not effectively manage vibrations and fastening forces.

Innovation Solution

The grinding machine housing device features a recording guide member with a main guide axis transverse to the power and output axle plane, an energy storage receiving interface with a rail-shaped or rib-shaped guide, and a damping unit to reduce vibrations, allowing for a compact and ergonomic arrangement of energy storage devices near the center of gravity, with a mounting guide unit for easy assembly and secure fastening.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If the energy storage receiving interface is arranged on the housing element with conventional guide elements, then the energy storage device can be detachably received, but the arrangement becomes non-compact and non-ergonomic, complicating the placement of energy storage devices and particle collecting containers

Engineering Contradiction:
Improvecompactness of energy storage interface arrangementVSAvoidergonomics of energy storage device arrangement
Core Design Contradiction:
Volume of moving objectVSEase of operation

Solution Approach 1:

The receiving guide element is oriented with its main guide axis extending substantially transversely to the input and output axis planes, creating a new spatial dimension for guiding the energy storage device. This transverse orientation allows the energy storage receiving interface to be compactly arranged on the housing element while maintaining ergonomic accessibility, resolving the contradiction between compactness and ease of operation.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Device complexity

If the receiving guide element is oriented parallel to the input and output axis planes, then the structure is simple, but the arrangement of energy storage devices becomes non-ergonomic and complicates the overall housing design

Engineering Contradiction:
Improvesimplicity of guide element structureVSAvoidergonomics of energy storage device placement
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

By orienting the main guide axis of the receiving guide element substantially transversely to the input and output axis planes, the design introduces a new spatial dimension that maintains structural simplicity while dramatically improving ergonomics. This transverse orientation enables intuitive placement of energy storage devices and particle collecting containers without complicating the guide element structure.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Device complexity

If the energy storage interface is arranged away from the center of gravity, then the housing structure is simple, but the hand tool becomes less comfortable and stable during operation

Engineering Contradiction:
Improvesimplicity of housing structureVSAvoidcomfort and stability of hand tool operation
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The transverse orientation of the receiving guide element enables the energy storage receiving interface to be positioned in a location that aligns with the center of gravity of the hand tool. This spatial reconfiguration, achieved through dimensional change in guide element orientation, improves balance and operational comfort without requiring complex housing structural modifications.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
