Bicycle Transport Case Retaining Device for Panel Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bicycle transport cases require users to carefully manage the orientation and extraction of bicycle frames to prevent damage during packing and unpacking, as they often rely on gravity to keep panels closed, which can lead to accidental opening and potential damage to wheels.
Innovation Solution
A bicycle transport case with a retaining device featuring a pivotally and detachably connected main guide rail and retaining stands that allow the bicycle frame to be securely positioned at various angular orientations, including upright, using quick release clamps and joint mechanisms to maintain stability and prevent panel collapse.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the container is opened and closed using gravity-based panel retention, then the structure is simple, but the panels may accidentally open and cause damage to the bicycle wheels
Solution Approach 1:
A retaining device is introduced as an intermediary mechanism between the container panels and the bicycle frame. This retaining device includes a guide rail and retaining stand that actively secure the panel in a closed position, preventing accidental opening while maintaining relative structural simplicity. The intermediary mechanism bridges the gap between simple gravity-based retention and complex active retention systems.
2Ease of operation
If the bicycle frame is retained upright for wheel extraction, then wheel removal is facilitated, but the frame orientation cannot be adjusted to various angles
Solution Approach 1:
The retaining stand is designed with movable and adjustable components that allow the bicycle frame to be secured in multiple orientations. The guide rail system enables the retaining stand to be positioned at different locations and angles, transforming the static upright retention into a dynamic system that can adapt to various frame orientations including upright, tilted, and horizontal positions.
Solution Approach 2:
The retaining device serves multiple functions: it can retain the bicycle frame in upright position for wheel extraction, secure the frame at various angular orientations for different packing configurations, and provide stable support during container opening and closing operations. This multi-functional design eliminates the need for separate mechanisms for different retention needs.
3Adaptability or versatility
If the retaining device is pivotally connected to allow various orientations, then frame positioning flexibility is improved, but the device complexity increases
Solution Approach 1:
The retaining device is segmented into distinct functional components: a guide rail system for positional adjustment, a retaining stand for frame support, and pivotal connection points for orientation flexibility. This segmentation allows each component to perform its specific function independently, simplifying the overall design while achieving complex retention capabilities. The modular structure reduces complexity by breaking down the retaining function into manageable, interchangeable parts.

AI summary
A bicycle transport case includes a container adapted to be opened and closed. The container includes a first outer side and a second outer side and has a chamber for receiving a bicycle frame defined by interior sides of the first and second outer sides. A retaining device configured to retain the bicycle frame at various angular orientations is pivotally and detachably connected to the container. The retaining device includes a main guide rail pivotally connected to the container about an axis and at least one retaining stand for retaining the bicycle frame movably mounted on the main guide rail and adapted to be locked in various positions on the main guide rail.
