Adjustable Laser Level Meter for Extended Levelling Height Range
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laser levels have a limited levelling height range, typically restricted to around 1.5 to 3.5 meters, which is insufficient for many practical applications that require levelling heights between 1 to 6 meters.
Innovation Solution
An improved laser level design incorporating a reference laser light source and an additional laser light source with an adjustable attitude, enabled by a rotatable pedestal, allows for the projection of a laser light line at adjustable angles, expanding the levelling height range beyond the conventional self-levelling height by adjusting the attitude of the additional laser light source to achieve horizontal alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If a conventional laser level structure with fixed laser light source height is used, then the structure is simple and easy to manufacture, but the levelling height range is limited to about 1.5 to 3.5 metres
Solution Approach 1:
The patent applies the dynamics principle by making the laser light source height adjustable rather than fixed. The level body can be positioned at different heights along the telescopic rod, allowing the laser light source to achieve different projection heights dynamically. This resolves the contradiction by enabling the levelling height range to reach 6 meters or more while maintaining a relatively simple structure through the use of a telescopic rod mechanism.
2Length of moving object
If the adjustable base (tripod) is used to adjust the laser light source height, then the structure remains simple, but the adjustment range is limited to a small amount within a limited extent
Solution Approach 1:
The patent replaces the limited-adjustment tripod with a telescopic rod that provides extensive height adjustment capability. The level body can be positioned at multiple heights along the telescopic rod, transforming the static height limitation into a dynamic adjustment system that achieves a levelling height range of 6 meters or more.
Solution Approach 2:
The telescopic rod structure divides the height adjustment function into segments, allowing the level body to be positioned at different heights along the rod. This segmentation enables fine adjustment of the laser light source height while maintaining structural simplicity.
3Length of moving object
If a telescopic rod is used to extend the levelling height range to about 3.5 metres, then the height range increases, but the structure becomes more complex and the maximum height is still insufficient for applications requiring 6 metres or more
Solution Approach 1:
The patent enhances the telescopic rod mechanism to provide even greater height adjustment capability, enabling the levelling height range to reach 6 meters or more. The level body can be positioned at different heights along the extended telescopic rod, dynamically adjusting the laser projection height to meet higher application requirements while maintaining structural simplicity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively increases the levelling height range to 6 meters or more, enhancing the practicality and application scope of the laser level by allowing precise adjustment of the laser light line to achieve desired levelling heights through manual or electronic control.

Data Source
AI summary
A laser level includes a level body, the level body including a body housing and a laser light source contained in the body housing, the laser light source configured to emit a laser light beam plane so as to project a laser light line on a target surface, the laser light beam plane configured to form an adjustable angle relative to a horizontal plane, and the laser level including a fixing structure configured to fix the laser light source such that the laser light beam plane projected therefrom is fixed at an adjusted angle, the laser light line providing a levelling height when in a horizontal state. The laser level further includes an adjustment means configured to adjust the attitude of the laser light source when the laser light line projected onto the target surface from the laser light source from a non-horizontal state to a horizontal state.
