Spectacle Temple Hinge with Clicking Feedback Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing temple adjustments for spectacles lack a mechanism for fine-tuning the angle while providing tactile feedback, making the adjustment process less intuitive and potentially uncomfortable for users.
Innovation Solution
A temple adjustment system featuring a hinge member with a first set of saw teeth and a connecting seat with a second set of saw teeth, which create a clicking sound when adjusted, allowing for precise angle adjustments with auditory feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a temple adjustment mechanism is provided without tactile feedback, then the adjustment process is simpler, but the user cannot intuitively sense the adjustment status
Solution Approach 1:
The patent applies the feedback principle by incorporating a clicking mechanism that provides tactile and auditory feedback to the user during temple adjustment. The first set of saw teeth on the hinge member engages with the second set of saw teeth on the connecting seat, creating distinct clicks that inform the user of the adjustment status and position, thereby improving ease of operation without excessive complexity.
Solution Approach 2:
The adjustment mechanism is segmented into distinct components: the hinge member with its first set of saw teeth, the connecting seat with its second set of saw teeth, and the pivot pins. This segmentation allows each component to perform a specific function while collectively providing the feedback mechanism, resolving the contradiction between simplicity and intuitiveness.
2Loss of information
If a clicking mechanism is added to provide tactile feedback, then user feedback is improved, but the device becomes more complex
Solution Approach 1:
The clicking mechanism provides immediate feedback about the adjustment status through tactile and auditory signals. The engagement and disengagement of the saw teeth sets create distinct clicks that inform the user of the temple's angular position and adjustment state, eliminating information loss while adding minimal complexity through the use of existing mechanical elements.
Solution Approach 2:
The patent merges the feedback function with the existing hinge and connecting seat structures. The first and second sets of saw teeth are integrated into the hinge member and connecting seat respectively, combining the adjustment function with the feedback function in a unified mechanism rather than adding a separate complex feedback system.
3Measurement precision
If the temple angle is adjusted without auditory confirmation, then the adjustment process is faster, but the user cannot confirm the precision of adjustment
Solution Approach 1:
The clicking mechanism provides auditory confirmation with each adjustment step, allowing the user to precisely sense the angular position and confirm the precision of adjustment. The distinct clicks occur at specific angular positions, enabling the user to quickly verify the adjustment status without adding significant time to the adjustment process.
Solution Approach 2:
The adjustment mechanism produces periodic clicking sounds corresponding to the engagement of the saw teeth sets at regular angular intervals. This periodic feedback pattern allows the user to quickly determine the precision of adjustment by counting and listening for the clicks, maintaining fast adjustment while providing confirmation of precision.

AI summary
A adjustment sound-generating temple includes a hinge member, a connecting seat and a temple. The hinge member has a first set of saw teeth and a pivot pins on one surface, the first set of saw teeth on the hinge member has an arc-shaped recess on the backside; the connecting seat is provided with an insert slot on one end and an extension rod on the other, which has two second set of saw teeth on each of its inner side. The temple is assembled by combining the hinge member and the connecting seat. The completed temple is then connected to the frame, forming a spectacle that makes clicking sounds when adjusting the temple's angle. The clicking sounds help to enhance the quality of the spectacle as a whole.
