U-Shaped Shelf Support Structure for Adjustable Load Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shelf apparatuses either allow for free vertical position adjustment but suffer from staggering and excessive exposure of attachment parts, or they prevent vertical adjustment at the cost of increased manufacturing expenses.
Innovation Solution
A support apparatus featuring a U-shaped pillar with sloped chip portions and a detachable support member that allows for free vertical positioning of loads while minimizing staggering and attachment part exposure, and reducing manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If multiple engagement claws are used to attach the bracket to the pillar, then the attachment strength is improved, but the attachment part becomes greatly exposed and staggering occurs
Solution Approach 1:
The invention extracts the attachment function from multiple separate engagement claws and consolidates it into a single integrated support member with engagement protrusions. This single support member engages with the chip portions to provide sufficient attachment strength while eliminating the multiple exposed claws, thus reducing attachment part exposure and staggering.
Solution Approach 2:
The invention merges multiple engagement claws into a single integrated support member structure. The support member incorporates engagement protrusions that interact with multiple chip portions simultaneously, combining the attachment function of multiple claws into one unified component, thereby reducing exposure and staggering while maintaining attachment strength.
2Adaptability or versatility
If multiple load support members are provided to allow free vertical position change, then the adaptability is improved, but the manufacturing cost increases
Solution Approach 1:
The invention makes the support member universal by enabling it to engage with multiple chip portions at different vertical positions. The support member can be positioned at any height by engaging with different combinations of chip portions, providing free vertical adjustability without requiring multiple different support members, thus maintaining adaptability while reducing manufacturing cost.
Solution Approach 2:
The invention introduces dynamic positioning capability where the support member can be freely positioned vertically by engaging with different chip portions. The detachable engagement mechanism allows the support member to be moved to different heights and securely attached, providing adaptability without requiring multiple fixed-position support members, thereby reducing manufacturing cost.
3Strength
If the engagement portion is inserted deeply into the hollow hole for secure attachment, then the attachment strength is improved, but the support member cannot be detached
Solution Approach 1:
The invention incorporates preliminary positioning features where the engagement protrusions are designed to align with and engage into the chip portions at predetermined positions. This preliminary alignment ensures secure attachment when engaged, while the modular design maintains detachability by allowing the support member to be removed and repositioned to other chip portions.

AI summary
A fixture member includes: a pillar having a substantially horizontal sectional shape that is a U-shape; a plurality of chip portions fixed in the pillar; and an opening formed by a lower surface of one chip portion, an upper surface of another chip portion, and opposed inner side surfaces of the pillar. A support member is detachably attached to the opening. A receiving member is fixed to the support member. The chip portion has an upper slope surface, a first horizontal surface, and a lower slope surface. The support member has: a first contact surface to contact with the lower slope surface; a second contact surface to contact with the upper slope surface; a third contact surface to contact with the first horizontal surface; and a fourth contact surface and a fifth contact surface to contact with the opposed inner side surfaces of the fixture member.
