Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laser levels can only produce one laser horizontal point and one laser horizontal line, limiting their ability to meet requirements for measuring or correcting objects in the horizon direction.
Innovation Solution
A laser level design incorporating a housing with a laser, a laser fixing plate, a front cover plate, a sliding block, and both minus-shaped and cross-shaped laser beam splitters, allowing for the conversion of laser output into mutually perpendicular cross laser lines and a minus-shaped laser line through the use of sliding block pushers and positioning components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional laser levels use a fixed single laser source, then the device structure remains simple, but the device can only produce one laser horizontal point and one laser horizontal line, limiting measurement capability
Solution Approach 1:
The patent implements a sliding block mechanism that allows dynamic repositioning of the laser source along the optical axis. This dynamic adjustment enables the single laser source to occupy different positions, thereby producing both cross laser lines and parallel laser lines, resolving the contradiction between measurement versatility and device simplicity.
Solution Approach 2:
The patent makes the single laser source perform multiple functions by enabling it to generate different types of laser lines (cross and parallel) through positional adjustment. The laser source serves universally for both measurement modes, eliminating the need for separate laser sources while maintaining measurement versatility.
2Adaptability or versatility
If multiple laser sources are used to produce both cross and parallel laser lines, then measurement versatility improves, but the device complexity and size increase
Solution Approach 1:
The patent employs a single laser source that can function in multiple modes by changing its position along the optical axis. This universal approach allows the device to produce both cross laser lines and parallel laser lines without requiring multiple separate laser sources, thereby maintaining compact device size while achieving measurement versatility.
Solution Approach 2:
The sliding block mechanism provides dynamic repositioning capability, allowing the single laser source to be moved to different positions along the optical axis. This dynamic adjustment enables the device to switch between producing cross laser lines and parallel laser lines, eliminating the need for multiple fixed laser sources and reducing overall device volume.
