Spring-Retained In-Frame Bicycle Display for Tool-Free Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic displays on bicycles, particularly electric bicycles, require fasteners for installation, which can detract from appearance, require tools for removal, compromise structural integrity, and increase manufacturing costs, while also posing a risk of moisture ingress.
Innovation Solution
A fastenerless display assembly is mounted within a bicycle tube using a housing with springs that constrain the display in multiple directions, including longitudinal, vertical, and lateral, providing secure retention without visible fasteners, suitable for various tube thicknesses and tolerances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fasteners are used to mount the display assembly, then the display can be securely retained, but the appearance is compromised, structural integrity is reduced, and manufacturing costs increase
Solution Approach 1:
The patent removes fasteners from the mounting system entirely, extracting the problematic element that compromised appearance and structural integrity. The display assembly is retained through the spring mechanism alone, eliminating visible fasteners and associated damage to the tube structure.
Solution Approach 2:
The patent changes the mounting mechanism from rigid fasteners to compliant springs, altering the physical parameters of the retention system. This allows the display to be securely held while accommodating tube thickness variations and maintaining aesthetic appearance.

AI summary
A display assembly for a bicycle includes: a housing; a plurality of springs attached to the housing and configured to maintain the housing in an installed position with respect to an opening, wherein at least one spring of the plurality of springs is configured to engage an inner edge of a portion of a wall surrounding the opening to provide a biasing force configured to at least partially bias the housing in a direction substantially orthogonal to an insertion direction, and wherein an upper portion of the housing is shaped to extend along at least the second direction beyond the inner edge, such that the housing is configured to only be insertable into the installed position from a position external to the internal cavity of the first tube; and a display coupled to the housing.
