Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Measuring the strength of a tree in a forest environment is labor-intensive due to the difficulty in accessing the measurement object, increasing the effort required for workers.
Innovation Solution
A cable-based measuring system that includes support posts, a winding device, a hoisting device, and a measuring device capable of moving in the air, which uses a pair of measuring terminals to detect the strength of a tree by outputting and detecting sonic waves, reducing the need for manual effort and enabling remote measurement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a worker moves to the position of the measurement object for measurement, then the measurement can be performed directly, but the effort of the worker increases and accessibility becomes difficult in forest environments
Solution Approach 1:
The patent introduces an overhead moving device as an intermediary carrier that transports the measuring device to the measurement location. The device includes a holding device to grip the tree and a measuring device to assess tree strength, both suspended from a cable system. This intermediary system eliminates the need for workers to physically access difficult terrain while maintaining measurement capability.
Solution Approach 2:
The patent replaces the manual mechanical approach of workers carrying measurement equipment with an automated cable-suspended system. The winding device winds the cable to move the overhead moving device horizontally, and the hoisting device hoists it vertically, substituting human physical effort with mechanical automation.
2Measurement precision
If workers manually transport measurement equipment to forest locations, then measurement can be performed, but the effort and time required increases significantly
Solution Approach 1:
The patent replaces manual transport of measurement equipment with an automated cable-based overhead moving device. The winding device and hoisting device work together to rapidly position the measuring device at the target tree location, eliminating the time-consuming manual carrying process through automated mechanical operation.
Solution Approach 2:
The overhead moving device is designed with dynamic positioning capabilities, allowing it to be moved horizontally by the winding device and vertically by the hoisting device. This dynamic system can quickly adapt to different measurement locations in the forest, reducing the time required to reach each measurement point compared to static manual transport methods.
