Electronic Apparatus Support Leg Parallel Folding Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing supporting devices for electronic apparatuses, such as those disclosed in Japanese Patent Application Publication No. 2004-266087, are inferior in usability due to the far-apart rotary supporting points of the stand and arm, leading to a long arm that overlaps with the stand when folded, compromising user convenience.
Innovation Solution
A supporting device with a leg and support mechanism rotatably attached to the back surface of the electronic apparatus, allowing for adjustable standing angles and folding in parallel without overlapping, utilizing a U-shaped leg and support with saw-tooth patterned sections and elastic engagement for secure positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the rotary supporting points of the stand and arm are placed far apart to provide structural stability, then the supporting strength is improved, but the arm becomes long and overlaps with the stand when folded, reducing usability
Solution Approach 1:
The patent changes the folding dimension from radial (overlapping) to linear (parallel alignment). By arranging the stand and arm to fold in substantially parallel to the back surface, the components utilize the depth dimension rather than overlapping in the radial plane, eliminating the overlap problem while maintaining structural stability.
Solution Approach 2:
The patent employs a rotatable support mechanism that allows dynamic adjustment of the leg angle with respect to the back surface. This dynamic capability enables the structure to transition between different configurations (folded and extended states) while maintaining stability in the extended state and compactness in the folded state.
2Stability of the object's composition
If the arm is made long to accommodate the receiving portion for the stand, then the structural integrity is improved, but the folded size increases, reducing portability
Solution Approach 1:
The patent reorients the folding motion so that the arm and stand fold parallel to the back surface rather than radially inward. This dimensional change allows the components to achieve a compact folded state without requiring excessive arm length, reducing the overall folded volume while maintaining structural integrity.
3Volume of moving object
If the stand and arm are designed to fold compactly, then the portability is improved, but the structural stability may be compromised
Solution Approach 1:
The rotatable support mechanism provides dynamic stability by allowing the leg angle to be adjusted and locked at different positions. When extended, the structure achieves optimal stability; when folded, it achieves compact volume. The rotational joints maintain structural integrity throughout the transition between states.
Solution Approach 2:
The use of rotatable joints and curved folding paths allows the structure to transition smoothly between extended and folded states while maintaining structural stability. The rotational motion enables the components to follow optimal geometric paths that preserve structural integrity during folding.

AI summary
For installing an apparatus body of an electronic apparatus at a standing state on a supporting surface, the supporting device includes a leg and support. The leg is rotatably provided on a back surface of the apparatus body at the standing state and is used for holding the apparatus body supported by the supporting surface. The support is rotatably provided on the back surface and engaged with the leg for defining an angle of the leg with respect to the back surface. The leg and the support are foldable in substantially parallel to the back surface without overlapping with each other.
