Saddle-riding Vehicle Storage Box Layout with Antilock Brake Control Unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing saddle-riding type vehicles face challenges in increasing the storage box capacity due to interference with seat rails and the layout of the antilock brake control unit, which affects the compactness and efficiency of the vehicle's components.
Innovation Solution
The design includes a seat supporting frame that crosses the fuel tank and supports the riding seat, allowing the antilock brake control unit to be positioned above the engine unit and covered by the seat supporting frame, enabling a more compact arrangement that increases storage box capacity without interfering with other components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of stationary object
If the storage box is disposed behind the head pipe and above the engine unit with the rear part above the front part of the seat rails, then the storage box can be positioned in the conventional layout, but the capacity of the storage box is limited due to interference with the seat rails
Solution Approach 1:
The patent applies dimensional change by repositioning the antilock brake control unit from a conventional horizontal layout to a vertical arrangement above the engine unit. This spatial reconfiguration in the vertical dimension allows the storage box to extend further rearward without interfering with seat rails, thereby increasing storage capacity while maintaining compact overall vehicle layout.
2Volume of stationary object
If the antilock brake control unit is disposed above the engine unit, then the storage box capacity can be increased, but the layout structure becomes more complex
Solution Approach 1:
The patent merges the antilock brake control unit with the engine unit mounting structure by positioning the control unit directly above the engine unit and integrating it with the existing frame structure. This consolidation approach increases storage box capacity while minimizing the addition of separate mounting structures, thereby reducing overall layout complexity.
3Strength
If the seat supporting frame crosses the fuel tank to support the riding seat, then the riding seat can be properly supported, but the fuel tank layout becomes more constrained
Solution Approach 1:
The patent segments the seat supporting frame into multiple sections, with the frame crossing the fuel tank in a controlled manner. This segmentation allows the fuel tank to be positioned in optimal locations while maintaining adequate seat support structure, thereby preserving both structural strength and fuel tank positioning flexibility.

AI summary
A saddle-riding type vehicle has a storage box disposed behind a head pipe and above an engine unit, a fuel tank disposed behind the storage box and obliquely above and behind the engine unit, and a riding seat disposed above the fuel tank. A seat supporting frame 77 extending rearward and upward from rear parts of a pair of left and right main frames 13 and crossing a front part of a fuel tank 19 is provided between the pair of left and right main frames 13 with an upper end of the seat supporting frame 77 supporting a front part of a riding seat 20, and an antilock brake control unit 37 is disposed at a position covered with the seat supporting frame 77 from above. This allows the antilock brake control unit to be provided without affecting the capacity of the storage box
