Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing weed removing tools fail to effectively eliminate weed roots, leading to regrowth and inefficiencies due to over-heating and turbulence issues, with limited development resources and precision in heating.
Innovation Solution
A weed removing tool with a cover body and support frame that forms a heat dissipation gap, adjustable heat dissipation port, and a root burning probe, allowing precise heating and soil loosening, while preventing over-heating and enhancing user safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the cover body is coated over the heating object without timely removal, then the heating effect is enhanced, but the entire heating object is over-heated and burned
Solution Approach 1:
The cover body is designed to be movable rather than fixed, allowing the operator to dynamically adjust its position and timing of removal based on the heating process requirements. This enables the cover body to remain in place long enough to achieve effective heating while being removable before over-heating occurs, thus resolving the contradiction between enhancing heating effect and preventing burning damage.
2Ease of operation
If the cover body is held manually during heating, then the heating operation can be controlled, but the force applied by hands increases the working load
Solution Approach 1:
The support frame provides mechanical support that counteracts the weight of the cover body, eliminating the need for the operator to manually hold it. This reduces the force and working load on the operator's hands while maintaining control over the heating operation through the support frame's stabilization mechanism.
3Measurement precision
If the air speed at the air outlet is adjusted, then the heating precision can be improved, but turbulence is caused during adjustment
Solution Approach 1:
The air speed adjustment mechanism is designed to enable smooth, progressive changes in air flow velocity. By allowing dynamic adjustment rather than abrupt changes, the system can optimize heating precision through controlled air speed variations while minimizing turbulence that would disrupt stable heating conditions.
4Productivity
If the heating device operates without precise positioning, then the device structure is simpler, but the heating efficiency is reduced
Solution Approach 1:
The support frame acts as an intermediary component that provides positioning functionality without requiring complex positioning mechanisms. It stabilizes the cover body at appropriate distances from the heating object, enabling precise heating positioning through a relatively simple mechanical support structure rather than complex adjustment mechanisms.

AI summary
A cover body for weed removing tool includes a heat dissipation port for heat dissipation. A cover sheet for regulating a size of the heat dissipation port is arranged at a position on the cover body corresponding to the heat dissipation port, and the cover sheet is connected to the cover body, and is subject to displacement relative to the cover body.
