Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional scanners face issues with cumbersome assembly and structural instability due to loose or shifted carbon fiber and metal components, affecting the stability and reliability of marker arrangements.
Innovation Solution
A scanner with an integral frame structure and embedded marker modules, where the frame is formed as an integral structure using a mold, incorporating interconnected struts and connecting portions for stable mounting of marker modules, ensuring consistent marker visibility and improved structural strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the frame is assembled from multiple carbon fiber plates and metal pieces, then the scanner can be constructed with available components, but the assembly process becomes cumbersome and structural stability deteriorates due to loose or shifted components
Solution Approach 1:
The patent merges multiple separate components (carbon fiber plates and metal pieces) into a single integrated frame structure. The frame is designed as one unified piece that incorporates all structural elements, eliminating the need for assembly of multiple parts. This resolving the contradiction by combining components to improve structural stability while maintaining ease of manufacture through integral construction.
2Adaptability or versatility
If markers are disposed on the outer periphery of an assembled frame, then the scanner can be constructed with modular components, but the stability and installation reliability of markers deteriorates due to frame component loosening or shifting
Solution Approach 1:
The patent combines the frame structure into a single integral piece, which provides a stable and consistent mounting surface for markers. By eliminating the assembled nature of the frame, the markers can be reliably installed on the outer periphery without concerns about frame components loosening or shifting, thus improving marker installation reliability while maintaining the ability to construct the scanner with available components.
3Strength
If the frame is formed as an integral structure, then structural strength and stability are improved, but manufacturing complexity increases requiring mold incorporation
Solution Approach 1:
The patent incorporates the frame structure and marker module mounting features into a single mold during the manufacturing process. By preparing the mold with integrated features beforehand, the integral frame structure can be manufactured in one process step, avoiding the need for complex post-assembly operations. This resolves the contradiction by performing preliminary mold preparation that enables integral structure manufacturing without excessive complexity.
