Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric motor-assisted bicycles face challenges in efficiently positioning multiple electronic devices on the handlebars without interference, particularly in a compact manner, due to limited space and visibility issues.
Innovation Solution
A display apparatus with a tubular connecting pipe and a display extending radially from the pipe, featuring a button orientation perpendicular to the pipe axis, allowing for adjustable positioning and miniaturization, and incorporating a connection port with perpendicular insertion/removal direction to simplify load-bearing structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If multiple electronic devices are mounted on the handlebars in a compact arrangement, then space efficiency is improved, but visibility and operational accessibility deteriorate
Solution Approach 1:
The display is positioned to extend radially outward from the steering axle in a direction perpendicular to the axial direction, utilizing the radial dimension to improve visibility and accessibility without occupying additional axial space on the handlebars. This dimensional reorientation allows the display to be compactly integrated while maintaining operational ease.
2Ease of operation
If the button is oriented with a larger perpendicular component for depression operation, then ease of operation is improved, but structural complexity increases
Solution Approach 1:
The button is designed with asymmetric orientation where the depression direction has a larger component perpendicular to the connecting pipe axis rather than parallel to it. This asymmetric configuration optimizes ergonomic operation while the connecting pipe's tubular structure provides inherent load-bearing capability that simplifies the overall support structure.
Solution Approach 2:
The connecting pipe serves multiple functions: it provides structural support for axial loads, positions the display radially outward, and accommodates the button's perpendicular depression operation. This multi-functionality reduces the need for additional separate structural components.
3Illumination intensity
If the display extends radially from the connecting pipe, then visibility is improved, but device complexity increases
Solution Approach 1:
The display extends in the radial direction perpendicular to the axial direction of the connecting pipe, utilizing the radial dimension to maximize visibility. This orientation allows the display to be clearly visible to the rider without requiring additional mounting structures or complex positioning mechanisms.
Solution Approach 2:
The connecting pipe acts as an intermediary structure that simplifies the mounting of the display. By providing a pre-formed tubular structure that can be mounted on the steering axle, it eliminates the need for complex mounting brackets or additional support structures, thereby reducing overall device complexity while maintaining radial extension for visibility.

AI summary
A display apparatus for an electric motor-assisted bicycle includes a tubular connecting pipe to allow a member coaxial with a steering axle of the electric motor-assisted bicycle to be inserted therein, and a display extending outward from the connecting pipe in a radial direction of the connecting pipe. The display includes a display surface to display a state of the electric motor-assisted bicycle and a button located on a surface of the display different from the display surface. A component of a depression direction of the button in a direction perpendicular to an axis of the connecting pipe is larger than a component in a direction of the axis of the connecting pipe.
