Solution Overview

Problem

Existing laser leveling devices lack user-friendly designs that allow intuitive operation, requiring repeated testing to recognize the function of control units.

Innovation Solution

The laser leveling device incorporates a control unit positioned between output domes, allowing intuitive operation by aligning control elements with the housing's surface normals, enabling direct recognition of their functions without repeated testing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the operating unit is arranged in a non-intuitive position on the housing, then the device structure is simplified, but the ease of operation deteriorates as users cannot intuitively recognize its function

Engineering Contradiction:
Improveintuitive operationVSAvoidhousing structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The operating unit is positioned in a specific location on the housing - between the output domes - creating a localized functional area that users can intuitively identify. This spatial differentiation allows users to recognize the operating unit's purpose without additional markings or repeated testing, resolving the contradiction between intuitive operation and structural simplicity

Inventive Principle:
Principle #3Local quality

2Ease of operation

If the operating unit is placed between the output domes, then user-friendliness is improved through intuitive recognition, but the housing design becomes more complex

Engineering Contradiction:
Improveuser-friendlinessVSAvoidhousing arrangement
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The operating unit is merged into the housing structure in a way that utilizes the existing spatial relationship between components. By positioning it between the output domes, the design combines the operating unit with the housing's natural geometry, improving user-friendliness while minimizing additional structural complexity

Inventive Principle:
Principle #5Merging (Combining)
