Eyewear Temple Resilient Assembly with Adjustable Retaining Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional eyewear temples are difficult to assemble and have a challenging combination strength adjustment due to complex assembly processes that can lead to potential damage during the assembly of the guide member and connecting rod.
Innovation Solution
The eyewear temple features a temple body with a chamber and retaining hole, incorporating a resilient assembly with a guide member, connecting rod, and spring, where the connecting rod is inserted through an opening and recess of the guide member, and a retaining part is inserted into a threaded or pyramidal hole, allowing for easy assembly and adjustable combination strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the connecting rod is screwed into the guide member adjacent to the shaft hole, then the conjunction is strong, but the large force applied may damage the conjunction between the connecting rod and guide member
Solution Approach 1:
The patent divides the connecting rod into two separate components: the connecting rod itself and the retaining element. The connecting rod provides the necessary strength for conjunction, while the retaining element positioned at the distal end provides damage resistance by engaging with the retaining hole in the temple body, away from the high-stress shaft hole area. This segmentation allows each component to optimize its function without compromising the other.
2Ease of manufacture
If the connecting rod is inserted through the side opening and recess of the guide member, then the assembly is easier, but the combination strength between the temple body and connecting rod is difficult to adjust
Solution Approach 1:
The patent makes the combination strength adjustable by allowing the retaining element to be positioned at different locations along the connecting rod. The distance between the retaining element and the shaft hole can be varied to adjust the lever arm length, thereby dynamically adjusting the combination strength. This dynamic adjustment capability is achieved while maintaining the simple insertion assembly process through the side opening and recess.
3Use of energy by moving object
If the connecting rod is forced during pulling to compress the spring, then the resilient function is achieved, but the conjunction adjacent to the shaft hole is applied with large force that may cause damage
Solution Approach 1:
The patent extracts the function of preventing damage from the conjunction near the shaft hole by introducing a separate retaining element. The retaining element engages with the retaining hole in the temple body at a location distal from the shaft hole, where forces are lower. This separates the spring compression function (performed by the connecting rod) from the damage prevention function (performed by the retaining element), allowing the harmful force concentration near the shaft hole to be avoided while maintaining the resilient function.

Function Achieved in This Case
This design simplifies the assembly process and allows for convenient adjustment of the combination strength between the temple body and connecting rod, reducing the risk of damage and making the assembly more efficient.
Implementation Method 1
The spring 87 is mounted around the connecting rod 86. Two ends of the spring 87 are connected to the connecting rod 86 and the seat 84 respectively.

AI summary
The eyewear temple has a temple body and a resilient assembly. The resilient assembly is mounted in the chamber of the temple body and has a guide member and a connecting rod. The guide member has a recess, a shaft hole, an opening and a through hole. The recess is axially formed in the guide member. The shaft hole is radially formed through the guide member. The opening is formed on a front surface of the guide member. The through hole is formed in a rear surface of the guide member. The connecting rod is easy to be directly inserted through the opening and the recess of the guide member, and is connected to the temple body. Therefore, the resilient assembly is easy to be assembled on the temple body, and the combination strength between the temple body and the connecting rod is easy to be adjusted.
