Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If laser ranging assembly and laser projecting assembly are directly assembled on the shell, then multifunctionality is achieved, but assembly complexity increases and assembly efficiency decreases

Engineering Contradiction:
ImprovemultifunctionalityVSAvoidassembly complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces an optical bracket as a separate intermediate component that segments the assembly process. The laser ranging assembly and laser projecting assembly are first fixed on the optical bracket, and then the optical bracket is assembled to the shell. This segmentation reduces assembly complexity by creating modular sub-assemblies.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The optical bracket serves as an intermediary component between the shell and the laser assemblies. It provides a standardized mounting interface that simplifies the connection process and reduces the number of direct fastening operations required between the shell and multiple laser components.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If more functional modules are integrated into the tape measure, then multifunctionality is improved, but volume increases and portability decreases

Engineering Contradiction:
ImprovemultifunctionalityVSAvoidvolume
Core Design Contradiction:
Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The optical bracket is designed to accommodate multiple laser assemblies (laser ranging assembly and laser projecting assembly) in a compact arrangement. By providing standardized fixing positions, it enables multiple functions to be integrated into a single device without proportionally increasing volume.

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

Solution Approach 2:

The optical bracket extends radially from the tape measure assembly, utilizing the radial dimension to position laser components. This allows the laser assemblies to be arranged in a compact three-dimensional configuration that minimizes the overall volume while maintaining all required functions.

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

3Adaptability or versatility

If laser ranging assembly and laser projecting assembly are fixed separately on the shell, then multifunctionality is achieved, but assembly time increases and productivity decreases

Engineering Contradiction:
ImprovemultifunctionalityVSAvoidassembly efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The laser ranging assembly and laser projecting assembly are pre-fixed on the optical bracket before being installed into the shell. This preliminary assembly action allows for standardized, repeatable mounting operations that reduce assembly time and improve productivity during final installation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

By segmenting the assembly into the optical bracket sub-assembly and the shell assembly, the patent enables parallel assembly operations. The optical bracket with pre-installed laser components can be prepared separately and then quickly mounted to the shell, improving overall assembly efficiency.

Inventive Principle:
Principle #1Segmentation
