Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional electronic devices with elevating mechanisms require a large number of parts and a larger support base to accommodate the mechanism, which increases complexity and space requirements.

Innovation Solution

The proposed elevating mechanism incorporates a rotational fastening element with wedging components and a twist force device, reducing the number of parts and optimizing space by using a support base with a rotating fastening element that engages the elevating element at different positions, allowing for height adjustment with fewer components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a conventional elevating mechanism with press switch and spring is used, then the elevating function is achieved, but the number of parts increases and the support base area becomes larger

Engineering Contradiction:

Improveelevating functionVSAvoidnumber of parts

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the press switch and spring into a single integrated fastening element. This fastening element includes a pressing portion that directly compresses the spring and a fastening portion that engages with the elevating element, eliminating the need for separate components and reducing overall part count while maintaining the elevating function

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The fastening element serves multiple functions: it acts as both the pressing mechanism (replacing the press switch) and the spring housing (replacing the separate spring component). The pressing portion compresses the spring to store energy, while the fastening portion with engagement protrusions secures the elevating element at different height positions, making one component perform the work of multiple parts

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If a conventional elevating mechanism with press switch and spring is used, then the elevating function is achieved, but the support base area becomes larger

Engineering Contradiction:

Improveelevating functionVSAvoidsupport base area

Core Design Contradiction:

ReliabilityVSArea of stationary object

Solution Approach 1:

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The spring is nested within the fastening element housing. The pressing portion of the fastening element directly compresses the spring which is contained within the same component structure, creating a compact nested arrangement that minimizes the space required on the support base while maintaining the energy storage and fastening functions

Inventive Principle:

Principle #7Nested doll (Nesting)

3Device complexity

If the number of parts is reduced, then the mechanism is simplified and space is saved, but the fastening reliability may be compromised

Engineering Contradiction:

Improvenumber of partsVSAvoidfastening reliability

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The fastening element is segmented into distinct functional portions: a pressing portion for compressing the spring and a fastening portion with engagement protrusions for securing the elevating element. This segmentation within a single component ensures that each function is properly executed while maintaining overall component integration and reliability

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The engagement protrusions on the fastening element and corresponding engagement grooves on the elevating element use curved surfaces that provide smooth engagement and disengagement. The curved geometry ensures reliable mechanical interlocking while allowing for easy operation, maintaining fastening reliability despite the reduced number of parts

Inventive Principle:

Principle #14Spheroidality (Curvature)

AI summary

An electronic device with an elevating mechanism includes a body and the elevating mechanism connected with the body. The elevating mechanism includes a support base, an elevating element, and a fastening element. The elevating element capable of moving between a first position and a second position relative to the support base is connected with both the support base and the body. The elevating element includes a first wedging component. The fastening element disposed around the second position relative to the support base is rotatable between a third position and a fourth position. The fastening element includes a second wedging component. When the fastening element is rotated to the fourth position, the second wedging component is wedged on the first wedging component for fastening the elevating element at the second position.
