Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laser rangefinders lack a means to securely attach to metal frames, leading to inconvenient operation and potential measurement inaccuracies due to hand shaking.
Innovation Solution
Integration of a magnet device that allows the laser rangefinder to be attached to metal frames via magnetic suction, ensuring stable positioning and reducing hand-induced measurement errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the laser rangefinder is held manually during measurement, then the device can be operated, but the measurement accuracy deteriorates due to hand shaking
Solution Approach 1:
The patent introduces a magnet device as an intermediary between the laser rangefinder and the metal frame. This magnet device enables the rangefinder to be attached to the metal frame without manual holding, thereby eliminating hand shaking while maintaining ease of operation. The magnet device acts as a mediator that transfers the attachment function from human hand to the metal frame surface.
2Measurement precision
If the laser rangefinder is attached to the metal frame using a magnet device, then measurement convenience and accuracy are improved, but the device complexity increases
Solution Approach 1:
The magnet device serves multiple functions: it provides attachment to the metal frame, enables stable positioning during measurement, and eliminates the need for manual holding. By integrating this single component to achieve multiple objectives, the patent reduces overall system complexity despite adding the magnet device.
Solution Approach 2:
The magnet device enables the laser rangefinder to attach itself to the metal frame autonomously without requiring additional fixing mechanisms or complex assembly procedures. The magnetic attachment is self-aligning and self-securing, simplifying the overall device structure while improving measurement stability.
