Resin Hammer Handle Without Core Prevents Silicon Impurities
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing hammers used for shape processing of silicon blocks, particularly those with a synthetic resin-coated core, face issues where silicon block fragments can enter the space between the core and resin, leading to scraping off of the core and resin, resulting in impurities entering the processed silicon piece.
Innovation Solution
A hammer design featuring a handle made of resin with a specific configuration, including a handle with a prismatic protrusion and a hammer head fixed to the handle using a pressing screw, ensures that no core is present inside the handle, preventing impurities from entering the silicon piece during processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a core is coated with synthetic resin to form a handle, then the handle structure is improved and manufacturing is easier, but silicon block fragments can enter the space between the core and resin causing scraping and impurity generation
Solution Approach 1:
The invention removes the core component from the handle structure, using only the synthetic resin material. This extraction of the core eliminates the space between core and resin where silicon fragments could enter and cause scraping, thereby preventing impurity generation while maintaining the handle's functional properties
Solution Approach 2:
The invention uses synthetic resin as a standalone material for the handle, eliminating the need for a core-resin composite structure. This single-material approach prevents the interface problems between different materials while maintaining the desired handle properties
2Strength
If a core-resin composite structure is used in the handle, then structural strength is improved, but the complexity of preventing fragment entry increases
Solution Approach 1:
The core component is removed from the handle structure, simplifying the design to a single synthetic resin piece. This eliminates the complexity of managing the core-resin interface and preventing fragment entry, while the resin itself provides sufficient structural strength for handle applications
3Object-generated harmful factors
If the handle is made of solid resin material, then impurity prevention is improved, but impact resistance may be reduced
Solution Approach 1:
The invention modifies the physical parameters of the resin material, specifically its hardness and elasticity, to achieve optimal balance between impurity prevention and impact resistance. By selecting resin with appropriate hardness (R90-R130) and elastic properties, the handle prevents fragment entry while absorbing impact forces effectively
