Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Spectacle temples are prone to unrecoverable deformation and random directional shaking due to vertical loads, affecting aesthetics and comfort, and existing solutions fail to effectively manage multi-directional loads.
Innovation Solution
A temple assembly featuring a guide member, first and second temple cores, and pivots that provide elastic force along the lengthwise direction, limiting swing positions and directions to absorb vertical loads and allow 360-degree rotation, preventing deformation and random sway.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the spectacle temple is connected to the front face via an elastic hinge for elastic closure and expansion in the horizontal direction, then the temple can achieve elastic opening and closing function, but the temple is prone to unrecoverable deformation when subjected to vertical forces outside the horizontal direction
Solution Approach 1:
The temple assembly is divided into multiple functional segments: a guide member that constrains movement to the horizontal plane, and a separate elastic hinge that provides elastic closure. This segmentation allows the guide member to prevent vertical deformation while the elastic hinge maintains its closing function, resolving the contradiction between adaptability and reliability.
Solution Approach 2:
The guide member acts as an intermediary component between the temple and the front face, mediating the movement constraints. It allows horizontal elastic movement while blocking vertical forces, thereby protecting the elastic hinge from damaging vertical loads while preserving the elastic closure function.
2Adaptability or versatility
If the temple allows multi-directional rotation for flexibility, then the temple can adapt to different wearing positions, but the temple produces random directional shaking that affects user experience
Solution Approach 1:
The system transitions from completely rigid constraints to dynamic constrained movement. The guide member allows controlled dynamic movement in the horizontal plane while preventing uncontrolled movement in vertical directions, achieving a balance between adaptability and stability for better user experience.
3Strength
If the temple structure is made rigid to prevent deformation, then the temple maintains structural integrity, but the temple loses elastic closure and expansion functionality
Solution Approach 1:
The temple assembly is segmented into a rigid guide member that maintains structural integrity and prevents deformation, and a separate elastic hinge component that provides the necessary flexibility for elastic closure. This segmentation allows both rigidity and elasticity to coexist in different parts of the system.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The temple assembly effectively absorbs vertical loads, prevents deformation, and enhances user experience by allowing smooth multi-directional rotation while extending the life of the hinge shaft, reducing random sway and maintaining frame aesthetics.
Implementation Method 1
a spring; wherein an end of the spring abuts against the fixing member, and the other end thereof abuts against the movable member; the movable member is reciprocally movable along the lengthwise direction of the spectacle temple body
Implementation Method 2
the guide member is in elastic abutment against the spectacle temple body and is configured to limit a swing position of a spectacle temple
Implementation Method 3
the first connecting end being pivotally connected with an end piece of a rim or an end hinge of a spectacle temple via the first pivot; the second connecting end being pivotally connected to the second temple core via the second pivot; the first pivot and the second pivot are arranged perpendicular to each other

AI summary
A temple assembly for a pair of spectacles, including a spectacle temple body (12), a guide member (13), a first temple core (14), a second temple core (15), a first pivot (16); and a second pivot (17); wherein the second temple core (15) is elastically connected with the spectacle temple body (12) and configured to provide an elastic force transmitted along a lengthwise direction of the spectacle temple body (12), the guide member (13) is sleeved on a periphery of the first temple core (14), and the first temple core (14) includes a first connecting end (141) and a second connecting end (142) disposed opposite to each other, the second connecting end (142) is pivotally connected to the second temple core (15) via the second pivot (17), the first connecting end (141) is pivotally connected to an end piece (110) of a rim (11) or an end hinge (18) of a spectacle temple via the first pivot (16); the first pivot (16) and the second pivot (17) are disposed perpendicular to each other; and the guide member (13) is in elastic abutment against the spectacle temple body (12). When the spectacle temples are subjected to loads in two different directions from a horizontal direction and a vertical direction, the spectacles temple cause to produce an elastic bend or an elastic swing of different directions at a front end and a rear end of the guide member spectacle temple body (13), and the present application avoids the feeling of random sway caused by elastic bending or elastic swing in two directions in the same portion of the spectacle frame spectacle temple body (10), the user experience that the temples can be rotated 360 degrees is better.
