Laser Distance Meter Slide Control for Measurement Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electro-optical distance meters, such as laser distance meters, are complex and difficult for users to operate due to multiple keys and functions, leading to uncertainty and measuring errors, especially for unpracticed users, and often go underutilized as users primarily use only basic functions.
Innovation Solution
A hand-held laser distance meter with a single slide-based operating element for triggering measurements, which simplifies operation and reduces the device's size while allowing multiple functions to be implemented without the need for multiple key presses, and includes a second operating element for stopping or restarting continuous measurements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple keys and functions are provided on the distance meter, then more functions can be implemented, but the device becomes complex and difficult to operate
Solution Approach 1:
A single operating element is designed to perform multiple functions including triggering distance measurements, selecting measurement modes (single/continuous measurement), and initiating area/volume calculations. This multi-functional design reduces the number of physical keys while maintaining comprehensive operational capability through context-sensitive function activation.
Solution Approach 2:
Multiple operational functions that would traditionally require separate keys are merged into a single operating element. The element combines measurement triggering, mode selection, and calculation initiation into one unified interface, simplifying the user interaction model while preserving all necessary measurement capabilities.
2Adaptability or versatility
If multiple keys are provided on the distance meter, then more functions can be implemented, but the device size increases
Solution Approach 1:
A single operating element is designed to perform multiple functions including triggering distance measurements, selecting measurement modes (single/continuous measurement), and initiating area/volume calculations. This multi-functional design reduces the number of physical keys while maintaining comprehensive operational capability through context-sensitive function activation.

3Adaptability or versatility
If multiple keys and functions are provided on the distance meter, then more functions can be implemented, but measuring errors increase due to user uncertainty
Solution Approach 1:
The operating element incorporates automatic function determination capability, where the system autonomously selects the appropriate measurement mode based on the current operational context and previously stored measurement data. This self-service approach eliminates the need for users to manually select modes, reducing selection errors and ensuring consistent measurement procedures.
Solution Approach 2:
The device provides visual feedback through a display unit that shows the currently active measurement mode and measurement status. This feedback mechanism helps users understand the device's current state and confirms proper operation, reducing uncertainty and improving measurement accuracy by ensuring users are aware of the measurement context.

AI summary
A distance measuring device, in particular a hand-held laser distance meter, includes a housing, transmission unit, receiving unit, and first operating unit. The first operating unit is arranged on the housing and configured to trigger at least one distance measurement, and includes a disk element. The transmission unit is arranged in the housing and is configured to transmit a measuring radiation in a direction of an object to be measured. The receiving unit is configured to receive measuring radiation returning from the object. A method for operating the distance measuring device includes starting at least one first distance measurement by moving the first operating element from a first a second position at which the device is deactivated to a first position, in particular along a measurement axis, to trigger the measurement, or in particular a sequence of continuous distance measurements.
