Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current flip chip systems for modifying bicycle geometry require complete disassembly of the rear suspension connection, making it difficult and impractical to change configurations during a ride, especially in mountainous terrain where handling small parts with gloves and multitools is challenging.
Innovation Solution
A novel flip chip system design that allows changing the chip position without completely extracting the screw, using sockets with cam-like cavities and chips with elongated bodies that can slide between positions, enabling geometry adjustments by loosening the screw and applying weight to the rear wheel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complete disassembly of the rear suspension connection is required to change chip position, then the connection is secure and reliable, but the operation becomes difficult and time-consuming
Solution Approach 1:
The connection system is segmented into modular components: the socket remains fixed in the frame, while the chip can be independently moved between positions. The screw serves as a separate fastening element that secures the chip in place. This segmentation allows the chip to be repositioned without requiring complete disassembly of the entire connection assembly, resolving the contradiction between maintaining connection reliability and enabling easy operation.
Solution Approach 2:
The chip is nested within the socket structure, with the screw passing through both components to secure them together. The elongated body of the chip fits within the cavity of the socket, creating a nested arrangement. This nesting allows the chip to be contained and secured within the socket while still permitting easy removal and repositioning by simply loosening the screw, without requiring complete disassembly of the connection.
2Adaptability or versatility
If the screw is completely extracted to change chip position, then the chip can be freely repositioned, but the operation becomes complex and requires multiple steps
Solution Approach 1:
Instead of completely extracting the screw to change chip position, the system uses partial action: the screw is simply loosened enough to allow the chip to be slid to a different position within the socket's cavity, then retightened. This partial action approach maintains the screw's securing function while enabling easy repositioning, significantly reducing operation complexity compared to complete extraction and reinstallation.
Solution Approach 2:
The elongated body of the chip is designed to self-guide within the cavity of the socket, allowing it to slide smoothly between positions without requiring manual manipulation or complex tools. The chip's own geometry facilitates its movement and positioning, reducing the complexity of the repositioning operation while maintaining adaptability.
3Adaptability or versatility
If traditional flip chip systems are used, then geometry modification is possible, but the process is impractical during rides in mountainous terrain
Solution Approach 1:
The system transitions from a static, fixed-connection design to a dynamic, easily adjustable design. The chip can be quickly repositioned between high and low positions by simply loosening and retightening the screw, allowing cyclists to adapt their bicycle geometry in response to changing terrain conditions during rides. This dynamic adjustability makes the system practical for use in mountainous terrain where conditions vary frequently.
Solution Approach 2:
The system enables easy change of the geometric parameter (chip position) by allowing the chip to be slid between predefined positions in the socket. This simple parameter change mechanism, achieved through the elongated chip body and cavity design, allows cyclists to modify their bicycle's geometry without complex procedures, making field adjustment during rides in mountainous terrain entirely practical.

AI summary
The invention discloses a flip chip type system (1) for changing the geometry of a bicycle by modifying the position of a connection of the rear suspension mechanism. However, the system (1) of the present invention differs from conventional flip chip systems in that the change in position can be carried out without extracting the connection screw completely. Thereto, the system (1) comprises, in a first component (3), sockets (32) having a cavity (34) defined by walls (35) provided around the hole (33) of each socket (32), and it also comprises chips (2) comprising a body (22) fitting into said cavity (34). However, unlike in conventional flip chip systems, the shape of the body (22) is configured in such a way as to alternate between said at least two positions by sliding against the walls (35) without exiting the cavity (34).
