Solution Overview

Problem

Existing clamping holders for mobile devices require two-handed operation or are prone to insensitive induction, making them inconvenient for one-handed use and susceptible to damage.

Innovation Solution

A clamping holder with a mechanical structure comprising a clamping mechanism, reset mechanism, and limiting mechanism, allowing for one-handed operation by using a sliding connector, reset spring, and locking assembly to securely clamp and release the device without electronic induction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a clamping structure is used, then the mobile device can be securely clamped, but two hands are required to operate it

Engineering Contradiction:
Improveclamping securityVSAvoidhands required for operation
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The reset mechanism automatically returns the clamping tabs to the released position after clamping, eliminating the need for manual operation to reset the device. The system serves itself by using the elastic restoring force to automatically return to the initial state, enabling one-handed operation while maintaining secure clamping

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The clamping mechanism transitions from a static two-handed operation to a dynamic one-handed operation by introducing a reset mechanism that automatically returns the clamping tabs to the released position. This dynamic system allows the user to clamp with one hand while the mechanism automatically resets without requiring the other hand

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If an inductive structure is used, then one-handed operation is enabled, but the electronics are susceptible to damage or insensitivity

Engineering Contradiction:
Improvehands required for operationVSAvoidelectronic sensitivity
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent replaces the electronic inductive structure with a mechanical reset mechanism that uses elastic restoring force. This mechanical substitution eliminates the sensitivity and damage issues associated with electronic induction while still enabling one-handed operation through automatic reset functionality

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The reset mechanism uses simple mechanical components including elastic elements and sliding connectors that are more durable and less susceptible to damage than electronic induction sensors. The mechanical system provides reliable operation without the fragility of electronic components

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Ease of operation

If the clamping tab moves freely, then the operation is simple, but the device may fall off due to insufficient clamping force

Engineering Contradiction:
Improveclamping operation simplicityVSAvoiddevice retention
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent merges the clamping function with a limiting mechanism that combines the simplicity of free movement with the security of restricted positioning. The limiting mechanism integrates multiple functions: allowing free movement during clamping operation while preventing excessive movement that would cause device drop-off

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The limiting mechanism acts as an intermediary between the freely moving clamping tab and the device being held. It mediates the movement by allowing necessary motion for clamping while restricting motion that would lead to device fall-off, thus maintaining both operational simplicity and device retention

Inventive Principle:
Principle #24Intermediary (Mediator)
