Bicycle Saddle Through-Hole Handle for Balanced Lifting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bicycle saddles lack an effectively placed and ergonomic handle for lifting and maneuvering, often compromising comfort, balance, and aesthetic appeal, with prior solutions being uncomfortable, unbalanced, or aesthetically detracting.
Innovation Solution
A bicycle saddle with a through-hole configured as a handle, positioned forward of the rear end, providing a secure grip and balanced control by allowing fingers to wrap around, maintaining aesthetic appeal and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a handle is added outside the standard seating area (behind or below the seat), then lifting capability is improved, but the bicycle balance becomes unbalanced and the handle position is not ergonomic
Solution Approach 1:
The opening in the saddle serves dual purposes: it provides clearance for soft tissue during riding and functions as a handle for lifting the bicycle. This multi-functional design eliminates the need for separate external handles while maintaining lifting capability and proper balance.
Solution Approach 2:
The lifting function is merged into the existing saddle structure by creating an opening that serves both as a tissue clearance feature and as a graspable handle. The bridge portion of the saddle forms an integrated handle rather than being a separate component.
2Area of stationary object
If the opening is positioned far forward of the rearward end, then seating surface area is improved, but the bridge portion becomes too long and narrow to be easily grasped
Solution Approach 1:
The opening dimensions are specifically configured with a lateral width greater than longitudinal length, creating a bridge portion with optimal width-to-length ratio for easy grasping. The opening size and shape parameters are adjusted to simultaneously provide adequate seating surface area and ergonomic handle dimensions.
3Ease of operation
If a pronounced ledge or extending handle is added to the saddle, then lifting capability is improved, but the aesthetic appeal is greatly reduced
Solution Approach 1:
The lifting function is integrated into the existing saddle contours through the opening design, eliminating the need for external handles or pronounced ledges that would compromise aesthetics. The bridge portion formed by the opening maintains the saddle's streamlined appearance while providing effective lifting capability.
4Area of stationary object
If the opening has insufficient lateral width, then seating surface area is maximized, but finger clearance for a firm grip is inadequate
Solution Approach 1:
The opening lateral width is specifically increased to exceed its longitudinal length, creating sufficient clearance for multiple fingers to wrap around the bridge portion for a secure grip. This parameter adjustment optimizes both seating surface area and grasping comfort simultaneously.

AI summary
A seat for a bicycle comprising: a seating surface having a longitudinal length, a longitudinally forward portion, a longitudinally rearward portion, and a lateral width between a first lateral end and a second lateral end laterally opposed to the first lateral end; an underside surface below the seating surface; an opening extending through the seating surface and the underside surface; where the opening has an opening length between a longitudinally forward periphery and a longitudinally rearward periphery and an opening width between a first lateral periphery and a second lateral periphery laterally opposed to the first lateral periphery; where the seating surface includes a bridge portion longitudinally located between the opening and the rearward portion of the seating surface; and where the opening has a lateral width greater than its longitudinal length.
