Solution Overview

Problem

Smart electronic devices, such as smartphones and personal computers, lack a convenient method for securely storing a pencil used for touch operations on touch panels, leading to inconvenience and potential loss.

Innovation Solution

A receiving device comprising a casing, guiding member, rotation member, key, and pushrod is designed to securely hold a pencil, featuring a receiving groove that can be opened and closed by the rotation member, preventing the pencil from falling out and allowing easy insertion and removal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a pencil is kept on an electronic device, then it is easily accessible for touch operations, but it may fall out or be lost

Engineering Contradiction:

ImproveAccessibility of pencilVSAvoidSecurity of pencil storage

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The receiving device is divided into a casing with a receiving groove and a rotation member that can rotate between covering and uncovering positions. The pencil is segmented from the storage space by the rotation member, which acts as a movable barrier. This segmentation allows the pencil to be securely held when the rotation member covers the groove, while still allowing easy access when rotated away.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The rotation member provides dynamic control over the pencil storage. It can rotate between a first position (covering the groove for secure storage) and a second position (uncovering the groove for easy access). This dynamic mechanism resolves the contradiction by allowing the system to switch between security and accessibility states as needed.

Inventive Principle:

Principle #15Dynamics

2Reliability

If a pencil is securely held in a fixed position, then it prevents loss, but it cannot be easily removed when needed

Engineering Contradiction:

ImproveSecurity of pencil storageVSAvoidEase of pencil removal

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The rotation member acts as an intermediary between the pencil and the external environment. When in the first position, it mediates by covering the groove to prevent accidental removal. When rotated to the second position, it mediates by exposing the groove to allow intentional removal. The guiding member further mediates by guiding the pencil during insertion and removal operations.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Adaptability or versatility

If a receiving device is added to an electronic device, then pencil storage is provided, but the device structure becomes more complex

Engineering Contradiction:

ImprovePencil storage capabilityVSAvoidStructure of receiving device

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The receiving device merges multiple functions into a single integrated structure. The casing with its receiving groove combines storage functionality, while the rotation member integrates both security (covering) and access (uncovering) functions. The guiding member combines guidance during insertion with prevention of lateral movement. This merging reduces overall complexity compared to having separate mechanisms for each function.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The rotation member serves multiple functions: it acts as a cover to secure the pencil, a door to allow access, and a indicator of the device state. The guiding member simultaneously guides pencil insertion, prevents lateral movement, and assists in pencil removal. This multi-functionality reduces the number of separate components needed, thereby reducing overall device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A receiving device includes a casing, a guiding member, a rotation member, a key, and a pushrod. The casing includes a baseboard, a first side plate, a second side plate, and a receiving member. The guiding member is received in the receiving member and defines a receiving groove. The rotation member rotatably covers the receiving groove and defines a bump element. The bump element is mounted on the first side plate through a first spring. The key is movably arranged in the casing. The pushrod includes a first end, a second end, and a spindle. The key is driven by an external force to drive the pushrod to rotate about the spindle, and the pushrod drives the rotation member to rotate until the receiving groove is no longer covered, thus the receiving groove is opened.
