Solution Overview

Problem

Existing radio-control transmitters with trigger-type configurations cause discomfort and pain due to high finger pressure when operating the brake lever, especially at the nail and skin boundary, leading to reduced operational ease.

Innovation Solution

A radio-control transmitter design featuring a brake lever that extends in a direction intersecting the imaginary plane, providing a larger contact area and reducing pressure on the finger, along with an adjustable rotation range and exchangeable brake lever structures for left- and right-handed users, to minimize discomfort and enhance operational ease.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the brake lever is designed to extend along the imaginary plane (parallel to the first lever), then the structure is simple and compact, but the contact area with the finger is small causing high pressure and pain

Engineering Contradiction:
Improvecomfort of brake lever operationVSAvoidstructure complexity of brake lever
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The brake lever is designed to extend in a direction intersecting the imaginary plane rather than parallel to it, adding a dimensional component that increases the contact area with the finger. This spatial reorientation distributes pressure more effectively across the finger surface, reducing pain and improving operational comfort without significantly complicating the overall structure.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If the brake lever is made fixed and non-adjustable, then the structure is simple and reliable, but it cannot be adapted to different hand sizes and finger thicknesses of operators

Engineering Contradiction:
Improveadaptability to different hand sizesVSAvoidcomplexity of adjustable mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The brake lever is designed with adjustable characteristics, allowing it to be modified according to different operators' hand sizes and finger thicknesses. This dynamic adaptability enables the same device to accommodate various users comfortably, transforming a static component into a user-customizable element without requiring complex adjustment mechanisms.

AI summary

A radio-control transmitter is provided which includes a trigger which has a throttle lever and a brake lever, wherein the throttle lever is capable of freely rocking with respect to a rotation shaft along an imaginary plane orthogonal to the rotation shaft and has a longitudinal direction parallel to the imaginary plane, and wherein the brake lever is integrated with the throttle lever and extends in a direction intersecting the imaginary plane.
