String Pinsetter Modular Assembly for Fast Bowling Lane Relocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing string-operated pin-setting apparatuses for bowling lanes are difficult and expensive to move due to fixed installations, requiring complex and time-consuming on-site assembly, which limits their versatility and application in temporary setups.
Innovation Solution
The apparatus features modular, dimensionally accurate structural parts with removable fasteners and pre-defined fastening holes, allowing for easy disassembly and reassembly without on-site machining, enabling quick and cost-effective relocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If fixed installation methods (welding, screws, glue) are used to assemble the pin-setting apparatus, then structural strength and stability are improved, but mobility and relocation ease deteriorate
Solution Approach 1:
The pin-setting apparatus is divided into modular components (pinsetter, backend, ball return unit, sidewalls) that can be independently assembled and disassembled. Each module contains standardized fastening interfaces that enable quick connection and separation without permanent attachment methods.
Solution Approach 2:
The fastening system transitions from static permanent connections (welding, glued joints) to dynamic reversible connections (removable fasteners). This allows the structure to adapt between fixed and mobile states, enabling easy relocation while maintaining structural integrity during operation.
2Manufacturing precision
If complex on-site assembly (welding, machining, precise alignment) is required, then assembly precision and structural integrity are improved, but installation time and cost increase
Solution Approach 1:
All dimensional precision requirements are satisfied during factory pre-assembly. Fastening holes, alignment features, and structural dimensions are precisely manufactured before shipment. This eliminates the need for on-site machining, measuring, and adjustment, reducing installation to simple fastener insertion.
Solution Approach 2:
Complex mechanical assembly operations (welding, on-site machining, precision alignment procedures) are replaced by pre-engineered mechanical interfaces with standardized fasteners. The precision is built into the components themselves rather than achieved through complex assembly processes.
3Strength
If permanent fastening methods (welding, riveting, nails) are used, then joint strength is improved, but disassembly ease and relocation capability deteriorate
Solution Approach 1:
The fastening system is designed to be dynamic rather than static. Removable fasteners provide permanent-level strength during operation but can be quickly removed for relocation. This dual-state capability resolves the contradiction between strong joints and easy disassembly.
Solution Approach 2:
The design allows for easy recovery and reuse of all structural components. Instead of permanent attachment that destroys or damages components during separation, the removable fastener system enables complete recovery of all parts for relocation or reuse at another site.
