Shock-absorbing Heel with Elastic Spring and Fastening Cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional high heel shoes with shock-absorbing features face manufacturing difficulties, complex mounting structures, poor durability, and inconvenience in replacing or repairing parts, leading to economic losses and reduced stability and comfort due to noise from moving elastic springs.
Innovation Solution
A heel design featuring an outer heel with an inner elastic spring, a replaceable top piece, and a cylindrical protection cap, combined with a fastening cover that limits the elastic spring's movement and distributes impact force, while allowing easy attachment and detachment for maintenance and design changes, and includes a lubricant to prevent noise and leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a shock absorbing member is installed inside the sole of conventional shoes, then shock absorption function is improved, but manufacturing complexity and mounting difficulty increase significantly
Solution Approach 1:
The heel is divided into separate components: outer heel, inner heel, elastic spring, top piece, and fastening cover. This segmentation allows each component to be manufactured independently and assembled later, simplifying the manufacturing process while maintaining the shock absorption function.
Solution Approach 2:
The inner heel with the elastic spring is nested inside the outer heel, creating a compact structure. The fastening cover then encloses both the inner heel and elastic spring, further nesting components within each other. This nesting approach reduces overall complexity while preserving the shock absorption mechanism.
2Stability of the object's composition
If conventional shock absorbing heels use fixed structures, then structural stability is improved, but ease of replacement and repair deteriorates
Solution Approach 1:
The heel structure transitions from a fixed design to a dynamic, adjustable system. The replaceable top piece and detachable fastening cover allow the structure to be modified, repaired, or updated without replacing the entire heel assembly, thereby improving ease of repair while maintaining structural stability during use.
Solution Approach 2:
The design allows worn or damaged components (top piece, fastening cover) to be easily discarded and replaced with new ones, while the main heel structure and elastic spring are recovered and retained. This extends the overall lifespan of the heel and simplifies maintenance.
3Adaptability or versatility
If the elastic spring is freely movable inside the outer heel, then shock absorption flexibility is improved, but noise and stability deteriorate
Solution Approach 1:
The fastening cover acts as an intermediary component that encloses the elastic spring and inner heel. It provides a confined space that allows the spring to move freely for shock absorption while preventing it from contacting the outer heel walls directly, thereby reducing noise generation while maintaining flexibility.
4Ease of manufacture
If the lower end of the inner heel is exposed to the outside, then ease of assembly is improved, but durability and aesthetic appearance deteriorate
Solution Approach 1:
The protection cap is nested over the lower end of the outer heel, creating a protective enclosure. This nested structure protects the inner heel's lower end from external damage and dust ingress, improving durability and aesthetics while maintaining assembly ease through the modular design.

AI summary
The present invention relates to a shock-absorbing heel provided with a shock absorber for mitigating the load applied to the sole of a foot when walking and, more specifically, to a shock-absorbing heel provided with a shock absorber and attached to a high heel, the shock-absorbing heel comprising, an outer heel fixedly mounted to the rear surface of the sole of a high heel (shoe), an inner heel which has an elastic spring mounted to the upper side thereof and is coupled to the inside of the outer heel, and a bottom heel which is fixedly mounted to a lower end portion of the inner heel so as to be replaceable, wherein a cylindrical protective cap which is inserted so as to prevent the lower end portion of the inner heel from being exposed to the outside is provided on a lower end portion of the outer heel, and a fastening cover coupled to the inner heel above the elastic spring is inserted into the outer heel. Thus, the outer heel slides up and down by virtue of the elastic spring to mitigate shock when walking.
