Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle cup holders with wireless charging capabilities have insufficient space for mounting a cup due to their structural design, and the charging efficiency is compromised by abrasion and foreign material introduction through traditional charging cables.
Innovation Solution
A vehicle cup holder with a rotatable mounting member that can change angles for wireless charging, incorporating a wireless power transmission module and operation mechanism to accommodate both charging and cup-holding functions, minimizing load and allowing user-adjustable terminal orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a wireless charging device in the form of a cup is inserted into the cup holder, then wireless charging function is provided, but the space for mounting an actual cup is insufficient
Solution Approach 1:
The mounting member is designed to be rotatable between a first state (inclined at an acute angle for wireless charging) and a second state (parallel to the side surface for cup accommodation). This dynamic reconfiguration allows the same space to serve different functions at different times, resolving the contradiction between providing wireless charging capability and maintaining sufficient cup mounting space.
Solution Approach 2:
The solution transitions from a static two-dimensional occupancy problem to a three-dimensional temporal solution. By adding the rotational dimension and time element, the mounting member can occupy different spatial configurations - when rotated to the first state it enables wireless charging, when rotated to the second state it provides full cup accommodation space.
2Productivity
If a charging cable is used to charge a portable terminal, then charging function is provided, but charging efficiency is degraded due to abrasion of charging port or introduction of foreign materials
Solution Approach 1:
The patent replaces the mechanical connection system (charging cable physically plugging into the charging port) with a wireless power transmission system. The wireless power transmission module transmits power through electromagnetic fields without physical contact, eliminating the mechanical wear and foreign material introduction problems associated with cable-based charging.
3Adaptability or versatility
If the mounting member is made rotatable to enable state conversion between wireless charging and cup accommodation, then functional versatility is improved, but load on rotation shaft increases
Solution Approach 1:
The rotation shaft is divided into multiple segments or sections with intermediate support structures. This segmentation distributes the mechanical load across multiple bearing points rather than concentrating it at a single shaft, reducing the stress and wear on each individual segment while maintaining the rotatable functionality.
4Device complexity
If the mounting member is fixed in a specific orientation, then structural simplicity is maintained, but user ability to adjust terminal orientation is limited
Solution Approach 1:
The mounting member transitions from a fixed static structure to a dynamically adjustable structure that can rotate between defined states. This controlled dynamics allows the member to maintain structural simplicity when in either the first or second state, while providing operational flexibility when users need to switch between wireless charging mode and cup accommodation mode.
