Spring Biased Bicycle Handgrip With Wing Shape
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bicycle grips are uncomfortable due to cylindrical shapes that cause fatigue, and materials like softer plastics decompose from perspiration, while the spring effect is minimal, leading to twisting issues and unsightly dirt deposits.
Innovation Solution
A bicycle grip with a wing shape featuring a support part, holding element, and a torque-proof spring element that allows rotational movement, using materials like wood or dense plastic, allowing for adjustable spring force and reduced dirt accumulation, with an ergonomic design that separates the spring effect from the material properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a cylindrical grip shape is used, then the grip can be easily manufactured, but the hand experiences fatigue and discomfort over time
Solution Approach 1:
The patent applies asymmetry by transitioning from a conventional cylindrical grip shape to an ergonomic wing shape with a support part for the ball of the hand. This asymmetric design provides a larger surface area for hand contact and proper anatomical positioning, significantly improving hand comfort and reducing fatigue during operation.
2Ease of operation
If softer plastic material is used for the grip, then comfort is improved, but the material decomposes due to hand perspiration and accumulates dirt
Solution Approach 1:
The patent employs composite materials by combining a firm plastic layer providing structural integrity and resistance to perspiration with a soft plastic layer providing comfort. This composite structure allows the grip to maintain durability while offering comfortable contact, resolving the contradiction between soft material comfort and material durability.
3Device complexity
If the grip is simply pushed onto the handlebars without a clamp, then the structure is simple, but the wing twists under load and becomes unusable
Solution Approach 1:
The patent applies segmentation by dividing the grip into distinct functional components: a gripping element, a support part, a holding element, and a spring element. This segmentation allows each component to perform its specific function - the holding element secures the grip to the handlebar while the spring element prevents twisting, maintaining stability without excessive complexity.
4Stability of the object's composition
If composite material is used to prevent twisting, then the wing position is stable, but the spring effect is small and hardly perceptible
Solution Approach 1:
The patent applies dynamics by introducing a spring element that provides active rotational movement capability. Unlike static composite materials, the spring element dynamically responds to applied forces, allowing the grip to twist and return smoothly. This creates a perceptible spring effect while maintaining positional stability through the torque-proof connection of the spring element to the holding element and gripping element.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides enhanced comfort and durability by allowing greater leverage and adjustable spring action, reducing fatigue and dirt issues, while enabling the use of previously unsuitable materials, and allowing individual adjustment of the spring force for customizable grip comfort.
Implementation Method 1
a spring element (5), which is connected in a torque-proof manner to the holding element (6) and to the gripping element (1), such that when a force is applied to the support part (3) against a spring force of the spring element (5), a rotational movement of the gripping element (1) about the central tube axis of the handlebar tube (12) can be carried out
