Solution Overview

Problem

Existing bicycle storage compartment lids face challenges in achieving watertight engagement and easy opening/closing due to complex shape requirements and thickness variability of bicycle tubes, particularly in carbon fibre and aluminium frames, often necessitating a plastic frame for adjustment, which limits suitability and watertightness.

Innovation Solution

A lid design featuring tracks and rotating arms that ensure watertight closure by pressing against the compartment edge, with an actuator mechanism allowing easy opening and closing, eliminating the need for a frame at the compartment mouth and accommodating varying tube thicknesses.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a plastic frame is added to the compartment mouth to accommodate thickness variability and provide desired shape, then adaptability to different tube thicknesses is improved, but device complexity increases and watertightness is compromised

Engineering Contradiction:

Improveadaptability to tube thickness variabilityVSAvoidcomplexity of compartment structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The lid incorporates an adjustable mechanism that allows the sealing surface to adapt to different tube thicknesses by changing its position or orientation, eliminating the need for a complex plastic frame while maintaining both adaptability and watertightness

Inventive Principle:

Principle #35Parameter changes

2Manufacturing precision

If a plastic frame is added to the compartment mouth to provide desired shape, then shape accuracy is improved, but manufacturing complexity increases

Engineering Contradiction:

Improveshape accuracy of compartment mouthVSAvoidease of frame fabrication

Core Design Contradiction:

Manufacturing precisionVSEase of manufacture

Solution Approach 1:

The invention removes the plastic frame component entirely, integrating the shape-providing function directly into the lid structure or the compartment opening, thereby simplifying manufacturing while maintaining shape accuracy

Inventive Principle:

Principle #2Taking out (Extraction)

3Reliability

If a complex closing system with multiple components is used to ensure watertightness, then sealing reliability is improved, but ease of operation deteriorates

Engineering Contradiction:

Improvewatertightness of compartmentVSAvoidease of opening and closing

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The lid integrates the sealing function and the opening/closing mechanism into a single unified structure, where the actuator directly controls the lid's movement while maintaining watertight engagement, eliminating the need for separate complex closing components

Inventive Principle:

Principle #5Merging (Combining)

AI summary

The invention discloses a lid (1) for a compartment in the frame of a bicycle. The lid (1) comprises: two tracks (4) provided on an inner face (2i) of a plate (2) in an elevated position with respect to said inner face (2i) and finishing in respective drops (4e) towards respective lengths (2t) of a perimetral band (2p) of the inner face (2i) located at opposite sides of said plate (2); and a rotating body (6) provided on the inner face (2i) and comprising two arms (6b) continuously biased towards the inner face (2i). When the body (6) is rotated by actuating the actuator (3), the ends of the arms (6b) follow the tracks (4) until arriving at a fastening position where they fall down the drops (4e) towards the respective lengths (2t) of the perimetral band (2p), thereby fastening the lid (1) in the closed position.
