Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current insect screen solutions with net guiding chains face difficulties in easy assembly, alignment adjustments during installation, and increased friction and wear due to misalignments, making them challenging for both skilled and unskilled personnel to install and maintain.
Innovation Solution
An insect screen system with a vertical box containing a winding roller, a horizontally sliding handlebar, and a net guiding chain, featuring a comb-like backing plate for alignment, sliding adjustment device, and friction-reducing sections to facilitate assembly, alignment, and reduce wear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a net guiding chain is used in the insect screen, then the net can be guided horizontally during operation, but the assembly becomes complex and alignment adjustments are difficult
Solution Approach 1:
The patent introduces an intermediary alignment system consisting of a comb-like alignment plate with positioning teeth that engages with corresponding positioning elements on the box and upper guide. This intermediary mechanism mediates between the complex net guiding chain and the installation structure, providing automatic alignment and positioning that simplifies assembly while maintaining the horizontal guidance function.
2Stability of the object's composition
If the box and upper guide are rigidly fixed, then the structure is stable, but alignment adjustments during installation are impossible
Solution Approach 1:
The patent implements a dynamic alignment system where the upper guide can be temporarily positioned and adjusted during installation using the comb-like alignment plate, and then fixed in the correct position. The system transitions from a static rigid structure to a dynamic installation process that allows adjustment, and finally locks into a stable fixed position once aligned.
Solution Approach 2:
The comb-like alignment plate with positioning teeth performs preliminary alignment action before the final fixed installation. The positioning teeth engage with corresponding elements to pre-position the box and upper guide in the correct alignment, making subsequent installation easier and ensuring proper positioning before permanent fixation.
3Ease of manufacture
If misalignment occurs during installation, then the structure can be assembled, but friction and wear increase during operation
Solution Approach 1:
The patent replaces the reliance on manual alignment skill with a mechanical alignment system. The comb-like alignment plate with positioning teeth provides automatic mechanical positioning that ensures correct alignment regardless of installer expertise, thereby preventing misalignment-induced friction and wear while maintaining assembly feasibility.
