Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pedaling measurement systems lack a reliable and efficient mechanism for attaching signal processing circuitry to a cycle's crank, which hinders accurate data collection and transmission of pedaling parameters.
Innovation Solution
A casing with a protrusion is designed to be attached to a cycle's crank, providing mechanical support and an electric connection to the spindle's measurement circuitry, enabling precise processing and transmission of pedaling data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a casing is attached to the crank to house signal processing circuitry, then measurement functionality is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple functions into a single integrated casing: housing signal processing circuitry, providing mechanical support for the spindle, and establishing electrical connections. This merging approach improves measurement capability while limiting complexity growth through functional integration rather than separate components.
Solution Approach 2:
The casing serves multiple purposes simultaneously: it acts as a protective housing for electronics, a mechanical mounting structure for the spindle, and an electrical connection interface. This multi-functionality resolves the contradiction by achieving enhanced measurement capabilities without proportionally increasing device complexity.
2Reliability
If a protrusion is added to provide mechanical support and electrical connection, then reliability of signal transmission is improved, but manufacturing complexity increases
Solution Approach 1:
The protrusion integrates mechanical support and electrical connection functions into a single structural element. By combining these functions in one component rather than separate parts, the patent improves reliability of signal transmission while avoiding the manufacturing complexity that would arise from assembling multiple separate components.
Solution Approach 2:
The protrusion acts as a multi-functional element providing both mechanical positioning/support and electrical connectivity. This universal design resolves the contradiction by achieving reliable signal transmission without requiring complex multi-step manufacturing processes.
3Stability of the object's composition
If the casing is securely attached to the crank, then measurement stability is improved, but ease of installation decreases
Solution Approach 1:
The protrusion is pre-formed as an integrated feature of the casing during manufacturing. This preliminary action creates a built-in alignment and attachment mechanism that ensures stable installation while simplifying the installation process itself, as the pre-formed structure guides proper positioning and securing to the crank.
