Solution Overview

Problem

Existing hand-held power tools lack a compact and efficient display solution that provides clear, visible information about tool parameters and states to operators, often requiring separate display elements and increasing assembly complexity.

Innovation Solution

A hand-held power tool design where the display element is formed in one piece with the housing connection element, allowing for a direct connection between the housing elements and providing a compact, integrated display that is visible between the motor and transmission housings, enabling easy assembly and secure fixing without additional separate fixing elements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a separate display element is used, then the display function is provided, but the assembly complexity increases

Engineering Contradiction:
Improveassembly complexityVSAvoidoperator feedback clarity
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The display element is integrated directly into the housing connecting element, merging two previously separate components (display unit and housing connector) into a single integrated component. This reduces the number of parts and assembly steps while maintaining clear operator feedback functionality.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of manufacture

If multiple separate fixing elements are used, then the connection between housing elements is secure, but the assembly effort and costs increase

Engineering Contradiction:
Improveassembly effortVSAvoidconnection security
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The housing connecting element serves dual functions: it connects the housing elements securely and integrates the display element. This consolidation eliminates the need for separate fixing elements, reducing assembly effort and costs while maintaining reliable connections through the integrated design.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The housing connecting element is designed as a multi-functional component that simultaneously provides mechanical connection and houses the display element. This universal design reduces the total number of components needed while ensuring both secure assembly and clear operator feedback.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

The invention relates to a hand-held power tool with at least one housing unit (12a; 12b; 12c; 12d; 12e; 12f) comprising at least one housing element (14a; 14b; 14c; 14d; 14e; 14f), at least one further housing element (16a; 16b; 16c; 16d; 16e; 16f) and at least one housing connecting element (18a; 18b; 18c; 18d; 18e; 18f) that connects the housing element (14a; 14b; 14c; 14d; 14e; 14f) and the further housing element (16a; 16b; 16c; 16d; 16e; 16f) together, and with at least one electrical and/or electronic display unit (20a; 20b; 20c; 20d; 20e; 20f), which includes at least one display element (22a; 22b; 22c; 22d; 22e; 22f) arranged at least partially circumferentially for displaying at least one characteristic of a hand-held power tool. It is proposed that at least the display element (22a; 22b; 22c; 22d; 22e; 22f) be formed at least partially as a single unit with the housing connecting element (18a; 18b; 18c; 18d; 18e; 18f).
