Solution Overview
Problem
Conventional angle adjustment mechanisms for electronic devices are complex, expensive, and difficult to assemble and disassemble, leading to increased costs and usability issues.
Innovation Solution
A compact and simple angle adjustment apparatus featuring a base with an engagement portion and a leg support that can be rotated to three positions: parallel, first inclination, and second inclination, with an auxiliary plate to stabilize each position, allowing easy assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional angle adjustment mechanism is used, then multiple inclination positions can be achieved, but the structure becomes complex and expensive
Solution Approach 1:
The angle adjustment mechanism is divided into separate functional components: a leg support with rotation axis for inclination adjustment, and a separate auxiliary plate with engagement projections for position stabilization. This segmentation allows each component to perform its specific function with a simple structure, avoiding the need for a complex integrated mechanism.
Solution Approach 2:
The leg support serves multiple functions: it provides the rotation axis for angle adjustment, supports the auxiliary plate, and enables transition between different inclination positions. The auxiliary plate similarly serves multiple functions including position stabilization and engagement with the base. This multi-functionality reduces the overall number of components needed.
2Reliability
If a conventional angle adjustment mechanism is used, then angle positioning can be achieved, but assembly and disassembly become difficult
Solution Approach 1:
The mechanism is segmented into independently assembleable components: the base, the leg support with rotation axis, and the auxiliary plate with engagement projections. These segmented components can be easily assembled by connecting them through the rotation axis and engagement projections, and disassembled by reversing the process, without requiring complex tools or procedures.
Solution Approach 2:
The auxiliary plate acts as an intermediary component that simplifies assembly and disassembly. Its engagement projections interact with the base structure to provide stable positioning while allowing easy attachment and detachment of the leg support from the base without requiring complex fastening mechanisms.
3Measurement precision
If additional components are added for angle stabilization, then positioning accuracy improves, but the device size increases
Solution Approach 1:
The stabilization function is merged into the existing leg support and auxiliary plate structures rather than adding separate stabilization mechanisms. The engagement projections on the auxiliary plate are integrated with the base structure, providing positioning accuracy without requiring additional space-consuming components.
Solution Approach 2:
The auxiliary plate uses a thin, flat structure with engagement projections that provide stabilization functionality without adding significant volume. This thin-film approach allows the stabilization component to be integrated into the existing device footprint without increasing overall device size.

AI summary
An angle adjustment apparatus for an electronic device according to the present invention can be inexpensively formed by a compact and simple structure and readily assembled and disassembled. When a telephone set as an electronic device is in a small inclination position, auxiliary plates are substantially in parallel to supports of a leg. Tips of the auxiliary plates are brought into abutment against right surfaces of the first projections. Click portions of the supports are brought into abutment against left surfaces of the second projections. Accordingly, the supports cannot be further rotated counterclockwise with respect to the base. When the telephone set is in a large inclination position, the auxiliary plates are perpendicular to the supports. The tips of the auxiliary plates are brought into abutment against the engagement portions of the base. The click portions of the supports are located between the first projections and the second projections. Accordingly, the supports cannot be further rotated counterclockwise with respect to the base.
