Laser Level Core Structure for Impact-Resistant Leveling Pins
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laser levels are prone to damage, particularly to the core structure and leveling pins, due to impacts such as drops or debris, leading to reduced durability and accuracy.
Innovation Solution
The laser level incorporates a core structure with leveling pins that utilize pin retainers and specific dimensions to distribute impact forces across multiple pins, reducing deformation and enhancing durability by spreading the load.

Engineering Contradiction Analysis
1Reliability
If conventional laser levels are used without enhanced core structure, then device complexity is low, but durability and resistance to impact damage are poor
Solution Approach 1:
The core structure is segmented into multiple leveling pins (first core retaining pin, second core retaining pin, biasing component retaining pin, and motor leveling pin) that are distributed to handle impact forces independently. This segmentation allows the structure to absorb and distribute impact energy across multiple discrete elements rather than relying on a single monolithic component.
Solution Approach 2:
A biasing component is pre-installed between the biasing component retaining pin and the second core retaining pin to provide beforehand cushioning. This biasing component acts as a pre-loaded energy storage element that absorbs impact forces before they reach critical levels, protecting the core structure from damage during drops or debris impacts.
2Reliability
If impact forces are concentrated on single leveling pins, then device complexity is low, but deformation and damage to pins increase
Solution Approach 1:
Pin retainers are introduced as intermediary components that connect and coordinate the leveling pins. The pin retainers distribute impact forces across multiple pins by providing a structural framework that transfers loads between pins, preventing any single pin from bearing the full brunt of impact forces.
Solution Approach 2:
Multiple leveling pins are merged into a coordinated system through the pin retainers, creating a unified force distribution network. The retainers combine the functionality of multiple pins into a single structural system that collectively resists impact forces, reducing deformation through shared load-bearing.

AI summary
Various laser level designs including an improved core structure are shown. In one example, the laser level includes housing, a core structure, and a laser generator positioned within the cores structure and/or the housing. The core structure further includes a plurality of leveling pins allowing for leveling in one or more directions and one or more pin retainers coupled to and extending between the leveling pins.
